Method and means for increasing energy output and thermal efficiency of an energy cycle such as the Rankine steam cycle

摘要

Multi-stage extraction steam is taken at varying pressures from a mixed pressure turbine and sequentially charged into closed path conveyor compartments to progressively increase the pressure of steam within the compartments. The highest pressure stage of extraction steam is then used to displace the steam from the compartments through a reheater and back to an injection station at the turbine, thereby repressurizing and reheating effluent turbine steam and returning it to the turbine for reuse without incurring the heat losses of condensation.
