TECHNICAL FIELD [0001] The invention disclosed herein generally relates to heatingsystemsacross gas fuel (LPG, Natural Gas, Bio-Methane or any Combustible Gas). More particularly, the invention disclosed herein relates to an internal combustion system on natural air draught configured to generate intense heat without the generation of soot through a newly designed radiant heat burner system. Further, the internal combustion system on natural air draught generates intense heat while consuming lower quantities of gas fuel.

BACKGROUND [0002] Energy consumption of a nation refers, in general, to the energy used by the population of a country. The energy consumed may be in the form of electrical energy,fossil fuel energy, renewable energy from wind, solar or waste management, energy for power generation, energy for cooking purposes, energy for manufacturing processes, energy for industrial applications, etc. It is widely acknowledged that the energy consumption of a nation is related to its economic growth. Further, factors such as population, demographics, industrial growth, etc., are also involved in the increase or decrease of energy consumption. In India, sectoral demand for energy arises mainly from lighting and cooking in the household sector, irrigation and other operations in the agriculture sector, and fuel input requirements and transport of freight in the industrial sector. With economic growth predicted to increase in developing nations, for example, India, energy requirements and energy consumption are set to grow by 4.5% per year by 2035, faster than all major economies of the world. In this regard, innovation in appliances or devices that are used frequently by a significant percentage of the population is imperative to bring down expenditure and consumption of energy. Furthermore, the innovation must seek to eliminate or reduce pollution generated by existing devices.

[0003] Currently, a significant percentage of Indian households depend on non- renewable resources, for example, wood, charcoal, etc., for their cooking requirements. Additionally, all over the world, fossil fuel and charcoal is depended on as the major source of energy to meet energy requirements. Over the years, several solutions have been proposed to reduce dependence on coal, wood, charcoal, etc., as their use contributes to increasing levels of Carbon dioxide in the atmosphere. For cooking, heating using advanced technologies such as microwave and induction heating has been in use. However, these technologies are expensive. Additionally, cooking using charcoal provides a distinctive taste due to the intense heat generated and the uniform heating of food. For example, the traditional tandoor requires intense heat about 480°C for extended periods to properly cook foods using radiant heat or convection heat. In such cases, massive quantities of fuel are required. Moreover, using charcoal or wood generates undesirable byproducts, for example, soot, carbon dioxide, etc. Consequently, vessels or utensils exposed to such heating systems are harder to clean and require additional quantities of water and cleansing chemicals. A system, which generates intense heat without generation of soot, is required. Moreover, a system, which generates intense heat for prolonged periods using smaller quantities of fuel, is required.

[0004] Additionally, conventional tandoors are a major cause of pollution as reported in a recent study commissioned by the Delhi government. According to the study, there are approximately 9000 restaurants in Delhi using coal fired tandoors. Such coal fired tandoors emit substantial amounts of Particulate Matter (PM) in the form of fly ash contributing to air pollution. According to the report, coal and fly ash are the largest contributors to PM 10 and PM 2.5 in the summers. Of the 37,171 kg/day and 18,369 kg/day of PM 10 and PM 2.5, the report shows 3,493 kg/day and 1,758 kg/day of the same particulate matter is from hotel and restaurant emissions. As such, the study states that under commercial activities, diesel generators and tandoors in restaurants are the highest contributors to air pollution in the city. Furthermore, the study suggests that about 67 per cent reduction of PM10 (2,142 kg/day) and PM2.5 (1,083 kg/day) emission from tandoors can be achieved by stopping uses of coal. Innovative technologies that eliminate the usage of coal are therefore a necessity to bring down pollution.

[0005] Anotherfundamentalrequirement of combustion in heating systems is air fuel mix. Typically, the air fuel mix is easy for heating systems using external combustion, asenough air is freely available. However, for heating systems using internal combustion need forced draught where air is pumped inside with the help of mechanical or electrical energy. Heating systems using internal combustion to achieve peak temperatures (more than 600°C) at the surface of the burner, invariably need forced air draught for combustion. Existing heating systems, for example, bio-mass stove, which is an external combustion stove, using fuel-wood or bio-mass pellets as the fuel source do not generate heat more than 500-600 °C in the combustible material. Additionally, these stoves require a fan backed by power to supply air for combustion. By taking this stove as an example for combustion one can realize how much artificially pumped air will be necessary if the same stove uses internal combustion. A system, which generates intense heat (greater than 600°C) at the surface of the burner without forced air draughts, is required.

[0006] Hence, there is a long felt but unresolved need for a system, which generates intense heat without generation of soot. Moreover, there is a need for a system, which generates intense heat for prolonged periods using smaller quantities of fuel. Furthermore, there is a need for a system, which generates intense heat (greater than 600°C) at the surface of the burner without forced air draughts.

OBJECTS OF THE INVENTION [0007] It is an object of the invention to provide a system, which generates intense heat without generation of soot. [0008] Yet another object of the invention is to provide a system, which generates intense heat for prolonged periods using smaller quantities of gas fuel.

[0009] Another object of the invention is to provide a system, which generates intense heat (greater than 600°C) at the surface of the burner without forced air draughts.

[0010] Another object of the invention is to provide a new radiant heat burner designed in a desired shape which gives fuel feeding from below instead of side. These burners can be clipped to expand to any size and the direction of fuel feeding can be turned to any direction. Where heat also can be stripped for balancing the heat which usually accumulates at the center for uniform heat transfer. The new design is especially configured for internal combustion for right air-fuel mix from below or above so that right air fuel mix can be calibrated & configured from above through the vent system for internal combustion on natural air draught.

SUMMARY OF THE INVENTION

[0011] This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter. [0012] The internal combustion system on natural air draught, disclosed herein, addresses the above-mentioned need for a system, which generates intense heat without generation of soot. Moreover, the invention addresses the need for a system, which generates intense heat for prolonged periods using smaller quantities of gas fuel. Furthermore, the invention addresses the need for a system, which generates intense heat (greater than 600°C) at the surface of the burner without forced air draught.

[0013] The internal combustion system on natural air draught for heating one or more target objects comprises a support structure, a mother base, and one or more radiant heat burners. The support structure comprises a first opening and a base platform. The first opening is positioned on a top surface of the support structure. The base platform is configured to house the one or more radiant heat burners and the support structure is configured to house themother base. The mother baseis positioned on the base platform of the support structure and comprises a top opening, an interior cavity, and a bottom opening. The top opening is configured to conform to the first opening of the support structure. The interior cavity extends between the top opening and a bottom opening of the mother base. Further, the interior cavity is configured to receive heat generated by the one or more radiant heat burners and supports the one or more target objects. The bottom opening of the mother base isconfigured vertically over the one or more radiant heat burners. The one or more radiant heat burners are configured to receive a fuel and a natural draught of air. A vent supplies the natural draught of air to ignite the fuel to generate heat for heating the one or more target objects.

[0014] The internal combustion system on natural air draught can attain peak temperatures higher than 600 °C at the surface of burner with natural air draught mechanism. Handling peak temperatures are an extremely challenging task as there are considerable safety risks. The internal combustion system on natural air draught has better energy efficiency as these devices do not produce any carbon soot. Generation of carbon soot is the major problem in present technologies working with charcoal and gas fuels. The generation of carbon soot is an indication that the fuel is not being combusted properly, hence combustion efficiency is not optimum. Theinternal combustion system on natural air draught allows heating using all the valuable properties of charcoal while mitigating all the problem areas associated with charcoal. The value property of charcoal is the generation of convection cum radiant heat, which gets generated by burning charcoal as it contains Far Infra-Red Rays (FIRR). These rays operate at a frequency of 300 GHz to 30THz, whereas Microwave and Induction Rays operate at a frequency of 300 MHZ to 300GHz. FIRR is a very potent energy as it produces uniform heat across the target object. Whereas the bad properties of charcoal including longer preparation time for combustion, emission of smoke, fly ash, non-regulatable heat, skill in handling the charcoal and not amenable to automation are mitigated. The above innovation completely addresses the problem areas of charcoal and provides only the valuable property of charcoal. Further, theinternal combustion system on natural air draught reduces the ambient heat not only by bringing energy efficiency but without producing any carbon soot. Thus, the innovation qualifies again to become the clean energy in this sector. These features take the application beyond Tandoori Oven as the temperatures generated is compatible for melting metals, producing heated air inside by drawing the air from outside instead of using the air from inside based on natural air draught.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] FIG. 1 exemplarily illustrates a perspective view of an internal combustion system on natural air draughtlOO. The internal combustion system on natural air draughtlOO for heating one or more target objects comprises a support structure 101, a mother basel02, and one or more radiant heat burners 103. As used herein, the term "target objects" refer to edible foods, metals, water, etc. The internal combustion system on natural air draughtlOO, disclosed herein, essentially works on radiant heat generated from multiple fuel sources, for example, gas fuels like liquefied petroleum gas (LPG), Natural Gas, Bio- Methane/Bio Gas, other combustible gases, etc. Further, the internal combustion system on natural air draughtlOO works on a supply of natural draught of air rather than forced air draught. As used herein, "forced air draught" refers to a process where a fan powered by a motor pumps external air into a system. In combustion, this system is used as air containing oxygen is the essential component for combustion of a solid, liquid, and gas fuel. Further, as used herein, "natural air draught" refers to a process where available air is supplied to a system with or without a vent system. Natural air draught is preferred in external combustion as air is readily available. Alternately, in an internal combustion application, forced air draught is preferred but consumes more power or sometimes requires supply of pressurized oxygen. Since the internal combustion system on natural air draughtlOO works on natural air draught and generates heat greater than when compared to applications using forced air draught, power savings are huge.

[0032] In existing gasfuel burners, combustion leads to flame which is blue in color, when enough oxygen is available in the air, or else, it turns into reddish orange color with carbon soot, which is a sign that fuel is not utilized to optimum level as its falling short of oxygen level. In an embodiment, the support structure lOlof the internal combustion system on natural air draughtlOO comprises a first opening 101a and a base platform 101b. The first opening 101a is positioned on a top surface 101c of the support structure 101. The base platform 101b is configured to house one or more radiant heat burners 103. The support structure 101 is configured to house themother basel02.In an embodiment, the mother basel02 is a cylindrical or cuboidal oven or furnace.As used herein, the "mother base" 102 is a heat resistant chamber externally coated with one or more insulation layers. As such, the "mother base" is configurable in different shapes and sizes based on the application requirement. For instance, the mother base 102 may be configured as a cooking range, a Hot Plate, Braising/Tilting Pan, Pizza Oven, Tandoor, Barbeque, Multi-Purpose Barbeque, Idli Steamer, Coffee Bean Roasting Machine, Steam Boiler, Heat Treatment Booth, Combi-Oven, Bakery Oven, Thermic Fluid Heater, Furnace, etc. [0033] The "mother base" device is provided with a radiant heat gas burnerl03 and vent system 104 which can be fitted into any device of any dimension and size, from any side. The installation of the mother base 102 transforms a gas burner system from external combustion to internal combustion of gas fuel. The mother basel02 is so potent that it has potential to use the available natural air draught as far as possible and the balance needed air-fuel mix can be fed with least forced draught if necessary. For most applications, the required heat is generated using natural air draught. The motherbasel02 is the base platform, which can get fitted to cooking range, hot plate, steam boiler, Heat Treament booth, etc., and transform an external combustion heat format to internal combustion heat format on gas fuel. While working on the mother base 102 into any system one can experience, while combustion, the phenomenon of rigid air and warm air moving inside and outside in the same vent systeml04. This phenomenon is not only capable of entrapping heat but also increases the energy efficiency by reducing heat dissipation. In the preferred embodiment, the support structure 101 comprises multiple legs with each leg having castor wheels for easier transportation of the internal combustion system on natural air draughtlOO. The radiant heat burner 103 is as defined in patent application 3397/CHE/2012 dated 17th August 2012 and patent application 2180/CHE/2014 dated 30th April 2014and incorporated herein by reference in its entirety. In an embodiment, the internal combustion system on natural air draughtlOO has option to be based on external combustion with obstruction or internal combustion with or without obstruction, where it is fitted with a non-return valve for improved safety and efficiency.

[0034] The external combustion with obstruction is a process where the radiant heat burners 103 derive its air-fuel mix from the open atmosphere. Alternately, the internal combustion is with or without obstruction where the radiant heat burners 103 are placed inside a closed chamber, and air fuel system is based on natural air draught by means of a vent 104 as exemplarily illustrated in FIG. 1. The radiant heat burners 103 have a higher thermal efficiency and generate convection cum radiant heat just like heat generated by charcoal.The mother basel02 is positioned on the base platform 101b of the support structurelOl vertically above the outlet of the radiant heat burners 103. The interior of the mother basel02 receives the heat generated by the radiant heat burners 103. The interior of the mother basel02 is heated to temperatures as high as 600°C at the surface of the burner. Any target object, for example, foods, metals, etc., can be heated as required. The heat within can be varied as per the target object being heated or according to the preference of the operator. The natural draught of air is supplied by a vent 104 to ignite the fuel supplied to the radiant heat burners 103 as disclosed in the patent application 3397/CHE/2012 dated 17th August 2012 and patent application 2180/CHE/2014 dated 30th April 2014.

[0035] The size and shape of the ventl04 varies from application to application. The vent 104 is configured in, for example, a rectangular, square, circular, irregular, or other configuration depending on heat format which need to be given. Alternately, the vent 104 may also assume a venturi configuration, a reverse venturi configuration, a convergent configuration, a divergent configuration, etc. As used herein, "Venturi" refers to a principle to drag air from big parcel to a small area either by forced draught or natural draught which is there in combustion process for a burner. There are no tubes at the bottom except for theradiant heat burners 103 placed in an airtight environment. The internal combustion of gas fuel in the radiant heat burners 103 is horizontal flame instead of vertical flame. Further, the radiant heat through gas fuel is flameless, smokeless, noiseless which is evenly spread across, whereas the blue flame is pressurized centric flame. The gas pressure used in the radiant heat burners 103 are very low compared to existing heating systems which work at high pressure. This lowers the risk factor and allows the internal combustion system on natural air draughtlOO to generate intense heat albeit safely. [0036] The thermal efficiency of commercial LPG radiant heat burnersl03 under IS 14612 is at 68.9% as against the existing burners ranging between 36- 45%. The shape and size of the ventl04 is created based on a mathematical model which considers different parameters, for example, pressure of gas, specific gravity of gas, surface area of burning, calorific heat needed, air fuel-mix balance, maximum - minimum heat cut of balance, design and shape of burner needed, placing of burner at top, bottom or at sides, etc. Depending on the requirement of a user the design of the ventl04 based on said mathematical model is created. The gas inlet for the radiant heat burners 103 is placed inside the chamber at top, bottom, side or at any angle. The vent 104 provides a perfect air-fuel mix on natural draught for optimum consumption to reach a desired temperature when ignited. In an embodiment, the vent 104 is positioned at a distance from the internal combustion system on natural air draught 100. The vent 104 may be positioned at such a place that the internal combustion system on natural air draught 100 does not extract and use air from the same room where cooking is done.

[0037] FIG. 2 exemplarily illustrates a perspective view of radiant heat burners 103 housed in a supporting structure 101 of an internal combustion system on natural air draughtlOO. In an embodiment, the support structure 101 is a cuboidal structure made of 20G Stainless Steel sheets. The frame of the support structure 101 without the stainless-steel sheets are shown in FIG. 2. The base platform 101b is configured to house the radiant heat burners 103. In an embodiment, the radiant heat burners 103 are of dimensions 20mmX6mm. The support structure 101 is configured to house themother basel02, exemplarily illustrated in FIGS. 1 and 3. In an embodiment, the height of the support structure is approximately 900mm, the length is about 950mm, and the width is about 780mm. In an embodiment, the mother basel02 is configured in multiple geometrical configurations, for example, hollow cuboidal configuration, hollow cylindrical configuration, hollow spherical configuration, etc., based on user preference or application requirements. For ease of transportation of the internal combustion system on natural air draughtlOO, the apparatus is provided with heavy duty castor wheels lOld having brakes as exemplarily illustrated in FIG. 2. [0038] In an embodiment, the radiant heat burner 103 is made up of a metal casing. Further, a metal mesh or a ceramic material is provided on a top surface of the radiant heat burner 103 for efficient heating. The size and geometrical configuration of the radiant heat burner 103 may be varied based on user preference or the intended application. For instance, the size of the radiant heat burner 103 may be made equivalent to the size of the mother basel02. Additionally, the radiant heat burners 103 may be of a cuboidal configuration, cylindrical configuration, etc. The radiant heat burner 103 may be fitted with accessories, for example, flame failure device, auto ignition device, timer and temperature control device, etc., based on the application or user preference. The internal combustion system on natural air draught 100 may also be fitted with sensors and data transmission devices for use in internet of things (IoT) applications,whose functioning can be monitored and controlled remotely using smartphones or other electronic devices.

[0039] FIG. 3 exemplarily illustrates a perspective view of a mother basel02 of an internal combustion system on natural air draughtlOO. As shown, the mother basel02 comprises a top opening 102a, an interior cavity 102b, and a bottom opening 102c. The top opening 102a is configured to conform to the first opening 101a of the support structure 101, exemplarily illustrated in FIG. 1. The interior cavity 102b extends between the top opening 102a and a bottom opening 102b of the mother basel02. The interior cavity 102b is configured to receive heat generated by the one or more radiant heat burners. Further, the interior cavity 102b is configured to support the one or more target objects. The bottom opening 102c of the mother basel02 is configured vertically over the one or more radiant heat burners 103 as exemplarily illustrated in FIG. 1. The one or more radiant heat burners is configured to receive a fuel and a natural draught of air. The mother basel02 is made of materials, for example, clay, metal, ceramic, etc. The mother basel02 is first covered with a layer of heat resistant material. A metal mesh or other suitable material holds the heat resistant material which is built around the mother basel02.

[0040] A metal sheet covers the mother basel02 with a gap to fill the mother basel02 with materials which prevents dissipation of heat. The mother base is totally insulated and retains heat efficiently. Moreover, the mother basel02 is further enclosed by the support structure 101 as exemplarily illustrated in FIG. 1. The heat entrapped inside the mother basel02 can be used for making Indian kebabs, Indian breads, etc. This format is also useful for other industrial heat applications, for example, smelting of metals, forging, blacksmith, etc. In an embodiment, the heat can be measured and controlled by automatic timer & temperature control system. It is also amenable for modern smart technologies, in which temperatures of the mother basel02 can be monitored remotely or on an electronic device, for example, a smart phone, a tablet, a mobile device, a computer, a laptop, etc. the internal combustion system on natural air draught 100 can also be configured to have an auto ignition feature which can be actuated remotely or at a preset time. In another embodiment, a flame failure device may be installed as an accessory. The flame failure device is configured to disconnect gas supply if the flame goes off accidentally or if there is a gas leakage from the gas supply. The internal combustion system on natural air draught 100 also finds applications in central heating systems and district heating systems in the air conditioning sector.

[0041] FIG. 4 exemplary illustrates a perspective view of a mother base configured as a heat treatment booth 400. FIG. 5 exemplary illustrates an exploded view of the mother base configured as a heat treatment booth400. The heat treatment booth 400 comprises a door 401 and a vacuum tube 402. The top, front, side, and rear panels 403 are provided to house the perforated sheets 405. The vent 404 provides a continuous supply of natural draught air to the heat treatment booth 400. Conventional commercial heat equipment working on gas fuels, for example, a Cooking Range, Hot Plate, Steam Boiler, HeatTreatment booth etc. works on external combustion producing vertical or linear blue flame. In such cases, the heat equipment derives the air-fuel mix from atmosphere either by forced draught or natural draught with thermal efficiency ranging from 30-45% under IS 14612. The first innovative heat equipment on gas fuel like a Cooking Range, Hot Plate, Steam Boiler, Heat Treatment booth etc. works on external combustion producing horizontal radiant heat, from any direction, deriving its air- fuel mix from atmosphere by natural draught with thermal efficiency higher than conventional burner system under IS 14612. The radiant heat from these devices can be obstructed without creating backfiring. The internal combustion system on natural air draught 100 converts existing heat equipment on gas fuel like a Cooking Range, Hot Plate, Steam Boiler, Heat Treatment booth etc., which earlier worked on external combustion to a heating equipment working on internal combustion thereby producing horizontal radiant heat, from any direction, deriving its air-fuel mix from the atmosphere by natural air draught. As such, the thermal efficiency of the present innovation is higher than conventional burner system under IS 14612. Furthermore, the radiant heat from these devices can be obstructed without creating backfiring.
