WASTED ENERGY SAVER FOR SHIP'S ENGINE
TECHNICAL FIELD
The present invention relates to the reduction of waste heat energy, in particular the reduction of waste heat energy produced from engines of ships.
PRIOR ART
It is well known that enormous amount of heat energy comes out of ships engines through exhaust chambers, with temperatures reaching above 300° . C. there were many significant inventions done in the last 15 years to get benefit of this wasted energy, through transferring this energy to steam boilers, and transferring it to electrical energy.
In this invention, the use of this wasted energy is more significant, because it will be used to take the maximum possible benefit of water physical properties, in order to reduce water drag significantly, and also to produce self-motivated energy from sea water. These advantages will improve energy consumption, top speed, and reduce C0 2 emissions from marine ships engines.
SUMMARY OF THE INVENTION
This invention is considered a significant improvement in reducing heat wasted energy from ships engines. It is preferred to take advantage from enormous heat energy which comes out from ships engines through exhaust chambers, and to preferably transfer this heat to the front edge of the ship, in order to raise the heat of the sea water in contact with the said edge surface, to reach temperatures exceeding 100° ό C, and to preferably take advantage of the physical properties of water, and the significant drop of its density when its temperature exceeds 100 ' C, this will reduce the drag significantly, which will reduce energy consumption for the ship's engine. Besides that, it is preferred to use the self- pushing force from water (from higher density water in the rear edge of the ship) due to water physical phenomena, besides drag reduction, which will increase the top speed of the ship significantly. All the mentioned advantages will reduce C0 2 emissions, and therefore will be considered environment friendly.
In one embodiment of this invention, the wasted energy coming out from marine ships engines through exhaust chambers, and which exceed 300°ό C, is transferred through metal heat transfer coils, to a pressure steam boiler, to control and enlarge heat as needed, and then this heat energy is transferred to the front edge of the ship. This heat energy is then transferred to sea water in contact with the ships front edge below water level. This heat energy will raise the said sea water temperature to reach above 100°ό C. At this stage water density is reduced significantly. This density reduction will reduce drag, and consequently increase ships speed and reduce energy consumption. Besides that, water will induce lateral force from the cold high density rear edge to the hot low density water at the front edge. This induced force will add to the propeller's moving force which also saves more energy. Less C0 2 emissions due to less petrol consumption will make this invention environment friendly.
Further embodiments of the invention are laid down in the dependent claims.
BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments of the invention are described in the following with reference to the drawings, which are for the purpose of illustrating the present preferred embodiments of the invention and not for the purpose of limiting the same. In the drawings,
Fig. 1 shows a longitudinal cross section of the marine ship.
DESCRIPTION OF PREFERRED EMBODIMENTS Figure 1 shows a longitudinal cross section of the marine ship. In this figure, the main engine 1 is shown, which the exhaust chamber 7 transferring exhaust gases to the chimney 8. A metal coil 2 is fixed surrounding the said exhaust chamber, and is connected to a metal heat transfer rod 3. The said rod is insulated by ceramic insulator 4. The said metal rod transfers heat energy to a steam boiler 6. The said boiler enlarges heat energy, and controls heat transfer through the insulated metal rod to a metal sheet 5 fixed on the front edge of the ship.
That is to say, Fig (1) shows a cross sectional view of the ship, where 1 is the main ship's engine, 7 is the exhaust chamber transferring hot gas emissions to chimney 8. A metal heat transfer coil 2 surrounding the said exhaust chamber and in contact to its surface, transfers the heat to metal heat transfer rod 3 which will transfer the heat to a pressure steam boiler 6. The said metal rod is insulated by heat insulator from ceramic material 4. The heat is transferred through the insulated metal rod to a special metal sheet fixed on the lower part of the ship's front edge 5, which is in contact of sea water opposing ships lateral movement causing drag. This heat transfer will increase the temperature of the sea water in contact to the said metal sheet 5 to reach the required and controlled temperatures. This increase in the said water temperature will lead to significant reduction to its density, which will lead to getting all the advantages explained before.
