<p>ENERGY CONVERSION METHOD AND SYSTEM A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200.degree.-400.degree.C. The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam. The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection. The compressor is driven by a heat engine whose reject heat is collected and upgraded as well. The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone. In cases where an aqueous feed medium is available at temperatures ranging from warm to hot, water vapor generated from the medium in initial evaporation stages may be delivered directly to a mechanical compressor without thermo-compression. Steam ejection may be dispensed with entirely if below-tepid temperature cooling capacity is not required from the system.</p> |
