A combination internal combustion and steam engine (10) includes a cylinder (12) having a piston (14) mounted for reciprocation therein with an internal combustion chamber (34) and a steam chamber (44) in the cylinder (12) adjacent the piston (14) and at least one steam exhaust port (50) positioned to communicate with the steam chamber (44) through the wall (12a) of the cylinder (12) for exhausting steam at a location in the cylinder wall (12a) adjacent to an engine cylinder cap surface (20) that is heated externally to assist in reducing chilling or condensation of steam entering the steam chamber (44) from a boiler (100) fired by waste combustion heat. The invention also permits steam admitted from a steam chest (46) jacketing the cylinder cap (20) to be exhausted from the engine (10) when the steam chamber (44) is in an expanded state whereupon residual steam is then recompressed prior to admitting the next charge of steam with the stream in the steam chamber (44) being heated directly by the combustion chamber (34) as well as by heat from the steam chest (46). An I.C. exhaust (37) powered heater (104) is a part of an I.C. exhaust manifold which functions as an afterburner with supplemental air injection (146) for promoting combustion of unburned exhaust constituents to superheat steam that is piped through it to the steam chest (46). The invention provides valves for balancing steam engine (10) displacement with boiler (100) output and for cylinder (12) compounding with a boiler (100), heat exchange (106, 108) and control (305) arrangement for efficiently recovering waste heat. | ||||||

In an energy conversion method and a thermal power plant for converting heat into mechanical or electric energy using a working medium, a vapor state in the working medium is generated at a first pressure in a steam generator. The vaporized working medium is expanded to a lower second pressure in a steam expanding device. An energy obtained by the expansion process is discharged. The expansion of the steam state is carried out using a saturation line of the working medium. The working medium is thereby separated into a non-condensed portion and a condensed portion in a separating device. The non-condensed portion is then compressed into a compressed non-condensed portion in a compressor. The compressed non-condensed portion is cooled and condensed into a compressed condensed portion. The compressed condensed portion and the initially condensed portion are then heated, and both portions are returned to the steam generator together. | ||||||
