Abstract
A new method, system and apparatus for power system utilizing wide temperature range heat sources and a multi-component working fluid is disclosed including a heat recovery vapor generator (HRVG) subsystem, a multi-stage energy conversion or turbine (T) subsystem and a condensation thermal compression subsystem (CTCSS) and where one or more of the streams exiting the stages of the turbine subsystem T are sent back through different portions of the HRVG to be warmed and/or cooled before being forwarded to the next stage of the turbine subsystem T. The turbine subsystem T includes at least a high pressure turbine or turbine stage (HPT) and a low pressure turbine or turbine stage (LPT) and preferably, an intermediate pressure turbine or turbine stage (IPT).
