Power system with enhanced thermodynamic efficiency and pollution control

摘要

An elevated pressure power plant (100) for cleanly and efficiently oxidizing, gasifying or combusting a fuel. The fuel is oxidized or gasified in a reaction chamber (210) at a pressure range from approximately 700 psia to 2000 psia, or from approximately 850 psia to 1276 psia. Products of combustion from the chamber may be passed to a heat exchanger (224). A portion of the condensed water may be recycled to the products of combustion upstream of the heat exchanger. Also, before being passed to the reaction chamber, the coolant may be routed through the heat exchanger in a two-step pressure fashion.
