PCT No. PCT/US93/10280 Sec. 371 Date Apr. 26, 1994 Sec. 102(e) Date Apr. 26, 1994 PCT Filed Oct. 27, 1993 PCT Pub. No. WO94/10427 PCT Pub. Date May 11, 1994A vapor-air steam engine is described which operates at high pressure and utilizes a working fluid consisting of a mixture of compressed uncombusted air components, fuel combustion products and steam. In the new cycle described, working fluid is provided at constant pressure and temperatures. Combustion air is supplied adiabatically by one or more stages of compression. Fuel is injected at pressure as needed. At least about 40% to all of compressed air is burned. Inert liquid is injected at high pressure to produce steam and thus provide an inert high specific heat diluent vapor required for internal cooling of an internal combustion turbine or other type system. The use of extensive liquid injection inhibits the formation of pollutants, increases the efficiency and horsepower of an engine, and reduces specific fuel consumption. The new cycle may also be operated open or closed; in the latter case, the liquid may be recouped via condensation for regenerative reuse. When salt water is injected into the system potable water is recovered from the steam exiting the power turbine and sterile sea salt is recovered from the combustion chamber. |
