This invention relates to improvements in system for utilizing fluid pressure and latent heat in condensed steam for pressure purposes.

In the ordinary power plants only a small percentage of the heat units of the common power, and the balfuels are converted into ance of power of the units is lost through the stack gases, exhaust steam, friction, radia-;

tion, etc. a

It is one of the objects of the present invention to overcome the before mentioned objectionable featuresand provide a system of utilizing fluid pressure in which the pressure medium or heat units are used a plurality of times to extract all of the heat and pres- A further object of the invention is to provide a system for utilizing fluid pressurein which boilers, engines, an air compressor, a steam condenser, an air heater, a super heater and a pump are connected together in a manner to utilize a larger percentage of thepowusual in common practice.

A further object of the invention is to provide system of utilizing fluid pressure which is very simple, is easily carried out, and is well adapted for-= the purpose described.

With the above and other objects in view, the invention consists of the improved system for utilizing fluid pressure and its parts and combinations as set forth in the claims,

and all equivalents thereof. 4

The accompanying drawing shows a diagrammatic view of the system for utilizing fluid ressure.

Re erring to the drawing, the numeral 5 indicates a main steam boiler, and 6 a super heater which may be of any ordinary type for super-heating steam for useQin an engine 7. The engine 7 is connected to the super heater 6 and the boiler 5 by a pipe 8 cons trolled by a valye 9. The steam in passing from the boiler to the engine 7 flows through thesuper heater 6 and is super-heated thereby. An exhaust pipe 10 connected to the exhaust opening .of the engine 7 extends and is connected to a closed type condenser 11 and the water of condensation from said condenshaust steam,

er flows through a pipe 12 a pump l3. The

operation of the pump will force the. water of condensation through the pipe 14 back to the boiler 5. n I

A heat exchanger 15 of the closed-typeis connected,by means of a pipe 16, to the pipe 14 or pump 13, and'receives water of condensation therefrom which is vaporized in said heat exchanger 15 and returns to the super heater 6 b a pipe '17. A check valve so 16 .is interp'ose between portions of said pipe 17 to prevent the return of steam to the heat exchanger 15. Valves 14' and 16' are provided for controlling the flow of water from the pump 13. i

air compressor 19 heats air or any inertnon-inflammable gas, which is preferably free. from moisture, by compression and forces said heated and compressed air through the pipe 20 andinto the heat ex- 7 changer 15 and 'vapori zes the hot condensed water within the tubes of theheat exchanger. The hot compressed airimparts sufficient heat to the hot water to vaporize it, "and then flows through a valved pipe 15 from the heat exchanger into an air engine -21, and the pressure of'the air is utilized to drive said air engine or other device. The air in passing through the heat exchanger 15 will lose av part of its heat, and in expanding in the air 9 7 engine will become comparatively cooI, and from the engine will pass through the pipe 22 to the condenser 11 and serve as the cooling medium for the exhaust steam passing through thetub'ular portion of the condenser 11. In passing through the condenser, the air or other fluid absorbs heat from the exand by means of the pipe 23, the partly heated air flows from the condenser to the air, compressor 19 before mentioned. Supplemental pipes 24 are connected to the'pipe 23 and include an air heater 25 to. permit additionally heating the air if desired. Valves 26 and 27 provide for controlling theflow of air from thecondenser diretly to the'air compressor or to the .air heater and then to the air compressor, or the valves m'ay be left open topermit part of the air to flow to the heater before entering the compressor. The super heater 6 and the air heater 25 are preferably placed in the chim ney flue 28 of the boiler 5 to receive heat from the hot gases of combustion from the heating means of the boiler 5.

"In use, the steam from the boiler 5 will actuate the engine 7, and the exhaust steam from the engine will flow through the condenser and be condensed by the cool exhaust air from the air engine. The Water of condensation will be returned to the boiler 5 and heat exchanger 15 by the pump 13. The cooling air after absorbing heat from the exhaust steam will be further heated in the heater and-will then be further compressed and heated by the compressor 19. The hot compressed air is then directed into the heat exchanger 15 to utilize the heat in the air to heat the water therein and generate steam which will supplement the steam of the boiler 5. The pressure of the compressed air after it has imparted its heat to the water in the heat exchanger 15 is utilized to drive the air engine 21. Furthermore, the air is quickly expanding in the air engine will become comparatively cool and this coolness is utilized in' the condenser as before described. Part of the water of condensation from the condenser 11 will be forced by the pump into the heat exchanger 15, turned into steam and the steam will flow to the boiler 5 or the super heater 6 for use in the engine 7 or any other power producing unit. The powerfrom the main and secondary engine may be used in any manner desired.

From the foregoing description it will be seen that the system for utilizing fluid pressure is very simple and is well adapted to utilize a large amount of the heat and pressure developed in the system.
