Abstract : The patent relates to a supercritical thermal power system including components conventionally included in a Rankine cycle, using a portion its own combustion gases as its only working fluid. The system recirculates all the combustion gases, cools them, and purges the excess amounts from the system. The cooled remainder portion is reheated to conserve energy and mixed with oxygen and fuel in the combustion chamber to lower the temperature of the burning gases. Cooler combustion gases are passed to a turbine for minimizing failure otherwise due to excessive heat in the system. By using a portion of the system's own combustion gases as the only working fluid, the system's overall efficiency is significantly increased over contemporary systems.
