However, this action results in a severe rise in the temperature of the gaseous projectile. The heat exchanger [HRSG] works on the one 55 hand to absorb the temperature and evaporate its water content and produce [Superheated] steam, and on the other hand it cools the dry gas and raises the capacity to higher pressure values. This led to formation of (conventional steam combined cycle) for energy recovery. 4- According to the claim element (3), the (combined steam cycle) consists of: - Superheated working medium; - Steam turbine; - Heat exchanger [HR]; - Control unit; and - Generator. 5- According to the claim element (4) the heat exchanger [HR] works to condense the steam from the turbine on the one hand, and to heat and adjust the temperature of the frozen dry gas entering the primary compressor on the other hand.

GENERATING ELECTRICAL ENERGY USING COOLED AND FROZEN DRY GAS MEDIUM DRIVEN BY KINETIC ENERGY
FIELD OF THE INVENTION
Electricity generation using science (gases and motion).
The target entity is the electric power stations.
This invention is concerned with the production and generation of economic electric power according to an engineering system different from traditional power stations, we mean here (steam) specifically, which is based mainly on the elements of heat mainly and steam as an intermediate only; And replacing that with the element of cooling and freezing, the medium used is “Dry Air” frozen and driven by kinetic energy; To move the turbines of a specially designed. With the addition of the combined cycle feature to recover energy.
BACKGROUND OF THE INVENTION
The science of energy production is based on the conversion of energy from one form to another. Various media are used in the power transmission process; For example, dam energy uses water as a medium, and thermal energy uses steam as a medium; In this new research, we will use cooled and frozen dried air as a medium to move the turbine.
Many innovations systems work to reduce the costs of energy production, and some of them are at the expense of the environment, such as coal energy; Others are clean but do not possess the driving force of the economy and industry; oscillating controlled by special conditions such as sun and wind energy; Others are governed by the supply and demand market, such as oil, instead of negative aspects such as carbon emissions; As for uranium, it is not easily accessible, not to mention the safety costs of irradiation residues.
Reducing the negative effects that accompany the old operations such as calcification, necrosis, cavitation and irradiation. Instead of the negative impact on the environmental and economic aspects resulting from the treatment of traditional fuel waste and the high cost of the cooling bill with the succession and convergence of periods of time for periodic maintenance operations. All of this had a great impact on the high bill of the basic energy industry.
In previous sciences, the traditional (single) cycle was used in the production of electrical energy, and the energy was very expensive. Then came the combined (steam) cycle to recover the wasted energy in the form of heat, which reduced a good amount of cost. What is new in our research is the combined cycle (using dry frozen air) in energy recovery and production.
Where the frozen gaseous medium is characterized by reducing the rates of negative effects associated with the old system in bulk, in addition to reducing harmful environmental emissions, and raising the economic efficiency of the facility by reducing the costs of electricity production, and even its ability to work in places with difficult natural resources, such as those that lack natural resources or suffer from their scarcity; This is because of the benefits of using the two composite cycles along with an isolated system, and energy cycling inward.
ADVANTAGEOUS EFFECTS OF INVENTION
The development of two systems in the generation of electricity:
The first: It is considered the least negative of the rate of carbon emissions, and the most abundant in energy productivity among similar power plants. The second: He is the most fortunate. Where it employs flow science and industrial control; And the use of the combined cycle (steam) along with the combined cycle (for frozen dry gas) to raise the efficiency of energy production.
And both methods run real energy that moves the wheel of the economy. (The impact of the two economic mechanisms will be shown in a table at the end of the research).
SUMMARY OF THE INVENTION - From the industrial reality, the generator to be operated and invested commercially is inspected. (Main station).
- Studies are carried out and analyzed carefully; And find out the operating mass of its volume (active mass).
- The active mass is divided into parts.
- These parts are distributed to small sub-stations in which the two combined cycles (conventional steam / frozen dry gas - new) are used:
- Steam sub-station (conventional).
-Pelton sub-station (will be explained).
It contains the main physical elements:
• Pressure values. P
• The area of the flow opening for the pressure unit A.
• The size of the compensating generator and its mechanism of action (will be explained).
• Efficient flow system . η
• Amount of suction volume from compressors. Q
• flux density, p
• Temperature flow . T
• Mass flow rate . m
2 - The type of working medium is dry, icy air. 3- First, the air is compressed after filtering and drying under high pressures, taking into account the rest of the main components in adjusting the mass flow rate.
4- A small-scale power substation is designed and structured. (Belton dry gas substation) The sum of these stations constitutes a major nucleus in the operation of the main power station to be invested.
The goal of the station is:
- Ensure the full flow of the gaseous mass affecting and operating the main station. Recovering the values of electricity consumed in the manufacture of gaseous projectiles.
- The station uses a gas flow system (that is not exhausted to its full potential) and this method of flowing is called [Underexpanded].
- The gaseous ejecta (the flow) is in the form of a linear (tangential) that contacts the line of the wheel of the Pelton turbine. (Fig. 1,2,3). The turbine design is similar to the Pelton hydro turbine, except that the design works with dry gas flow according to the flow conditions and many elements have been taken into account in it. (will be explained)
- min = mout
As for what it produces (Pelton Substation for Electricity) goes to the national public grid [inward] (gas combined cycle system); In a process to raise the efficiency of the produced energy by recovering the energy that was consumed during the operation of compressors and others for the manufacture and preparation of the gaseous projectile.
- The process of drawing energy from the public network and returning it is simultaneous (at the same time) after completing the precise initial operating procedures. 5- Then comes sizing. Finally, the number of Pelton substations is summed, each of which has a partial amount of the main mass flow rate; In a comprehensive and harmonious engineering design (Fig. 9), a single mass ratio is formed.
6- During the release of the gaseous projectile, a sharp drop in temperature results. It is used in the process of gas drying and cooling, which reduces operating costs and raises the efficiency of the energy produced.
7- The system can be isolated in certain locations to ensure the stability of the flow characteristic.
The system is characterized by a closed cycle of dry gas (reversible flow characteristic); So that there is no need to spend more energy in drying the gas again. It uses the same gas, it is controlled and prepared at its exit from the main turbine of the main investment station at a certain temperature, sucked through compressors and then pressed towards the Pelton sub-station for electricity again... and so on.
The system is characterized by a closed cycle of cold water (reversible flow characteristic); Where water tanks are developed in which very low temperatures are used and cold water is transferred and distributed to the entire project tools. This procedure will not affect the flow quality inside the tubes; Because the cooling that occurs inside the tubes is caused by the factors of pressure dissociation and the rapid expansion of gas molecules, and this means continuity.
Air drying (freezing) is a highly efficient method. Where the particles of water droplets carried by the air fall and are thrown out of the system through techniques (traps) as if they are dust, so that the medium becomes dry and suitable for operation. In special places in the pipes where the temperature drops, heat exchangers will be used to control the characteristic of the gaseous projectile on the one hand, and to complete the work of the first (steam) combined cycle on the other hand, and the combined gas cycle on the other.
The industrial solutions in the field of control are wide. High speeds can be controlled by fixed air guides; It can also prevent the formation of shock wave lines by installing mesh filters in studied locations. And many, many more.
* In meeting these specifications means raising the production capacity of the main investment station.

The element [1] represents the unit for filtering and drying air for introduction into the working tubes and tools of the system; This system will not be needed only in the first hours of operation. Later the circuit will be closed and isolated.
The two elements [2-4] (they are the main compressors operating on dry gas; their goal is to give the gas a laying energy and then release the energy and give the gas a speed equivalent to the freezing that occurs; which keeps the gas dry and provides the appropriate dry icing stream through which the mass is made and the recipe of the projectile The gaseous.

1- The primary compressor. ( LP )- STC-GV type.
2- Secondary compressor. ( HP )-BCL type.
- The ability of compressors to eject a mass rate of [m = 139.9 kg/sec] was studied. -Temperatures were calculated for each stage.
- The pressure rates and the amount of pressure drop after cooling were calculated in a process to raise the compressor capacity and perform the required pressure requirement.
- Calculating the efficiency of compressors η when polytropic. * Calculate the efficiency of η compressors.

Calculate Efficiency for the Primary Compressor: (Q1)
Calculate Efficiency for the Secondary Compressor: (Q2) * Compressor design equations and gas stream characterization. Gas specifications before entering the primary compressor Specifications after leaving the primary compressor
Specifications after exit from the heat exchanger Specifications after exit from the second compressor element [5] It is the substation of the electricity (Pelton), which is a compensating station whose objective is to recover the energy that was consumed in the manufacture of gaseous projectiles, and then return it to the main provider of the facility [the National Public Electricity Network] simultaneously and immediately, to raise the efficiency of energy production and raise the economic value of the electrical system as a whole, (to be proven) element [6] It is a (Pelton) turbine named by it because it is similar to the Pelton water turbine, except that it works by gas flow and its thrusters are designed to withstand a pressure of 300 bar. The Pelton turbine is exposed to the gas stream flowing from the compressors, under high pressure and then passing through a nozzle-like passage, and the gas expands without depleting its full potential (Underexpanded flow); At the exit appears some residual pressure values. The Residual Stream is used in the manufacture and refrigeration of the gas stream flowing and driving the turbine of the main investment power station. Pelton turbine design (Pelton wheel): see Figure (2), and Figure 1-2, and we will return to it for more details.
Analyze and compare the two working systems (steam vs. dry air) and mass splitting and load distribution to arrive at the size of the Pelton generator: * Design of the generator of the Pelton power station in its final size: - Here we have the features of the "combined dry frozen gas cycle" where:
# 0.74433% of the value of the electricity spent in the manufacture of gaseous projectiles was recovered to raise economic efficiency.
(see table) element [7] It is the gas pipeline outlet of the Pelton turbine. (The conveyor tube is similar to a nozzle. It causes the gas to expand very quickly, thus producing the required cooling; it is governed by controls that impose storm current instead of shock current; using special filters that allow the flow of the current and never obstruct it; but these filters prevent the formation of shock wave lines) .
The coldness inside this duct is never affected by the drop in its values. This is due to the continuous rapid expansion process inside the tube. Which means the continuity of the cooling process and the possibility of using continuous tubes in the cooling process on the heat exchangers.
The gas expansion process will stop only when the velocity decreases and the pressure (potential energy) inside the tube is exhausted and equal to the atmospheric pressure. This takes place from inside the Expander base station to the inlet of the primary compressor. element [3] It is a heat exchanger (HSRG) that absorbs heat from gas compressors and converts it into ( steam ) . At the same time, the main gas stream flowing from the compressors is cooled. To combine with the elements of the traditional [combined cycle] in the conventional steam power plant is an element [10], Compensating a difference from the cost of manufacturing pressure (manufacturing the adjective gaseous adjective).. element [13]
It is a cold water tank with a temperature of up to (5C°) that supplies the heat exchanger.
The condensed steam from the power plant turbine is transmitted through a steam trap (trap) to pump the hot water to another heat exchanger (HR) to cool it. element[12]
It is a heat exchanger (HR) that receives hot water condensing from steam due to its depletion of its potential energy. The gas stream coming from the turbine of the main investment station is heated (from -160 C° to -28 C°) in a process to adjust the density for the manufacture of the gaseous ejecta mass (rh = 139.9 kg/ sec). Then the cooled water is pumped back into the tank.
Here we show an approximate value of the traditional steam combined cycle.
Waste heat from compressors was reused and recycled in energy production, which contributes to raising energy efficiency and offsetting the costs of the pressure industry. Operational specifications of the steam plant (combined cycle): element [8] It is the main investment power station operating with a combined turbine. element [8-1] It is the expander composite mam power plant [Axial + panki]. The horizontal thrust current and the vertical suction current are received. See Figure (8).
- Dry gas is never subjected to liquefaction because it has not gone through all the critical conditions of dry air. Approximate overall scheme of the system: * Suction pressure rate from (industrial table).

It acts as a positive drag for the turbine fans (the direction of drag is in the same direction as the flow). Multiplied by 21 stations, which means 73.5 bar. As in Figure (8). Forming the suction force of the fans. 5 - (7.3 bar) is the result of the remaining total pressure residues operating at the
Pelton substation (300 bar), where its expansion was used in the freezing of gas (Frozen gas) and the manufacture of the main thrust force (thrust force) striking the expansion of the (turbine) of the main investment power station . Multiply at 21 stations which means 153.3bar making up the thrust for the fans. 0 (will be demonstrated) as in Figure (8). 7- Analysis of the thrust and positive drag forces at the Pelton gas turbine.

Thrust force: Suction speed made by primary compressor:
The compressor works on suctioning the air strongly (especially if it is cold and high in density), which speeds up the process of expanding and decompressing the compressed gas.
And we'll call this positive air drag because it's in the same direction as the thrust. Drag Force:

This answer is positive; The torque is completely covered, starting from 1.42 meters, and the greater the diameter from this threshold, the greater the torque on the turbine.
This ensures the smooth flow and safety of the facility's work continuity
