Method and apparatus for combined-closed-cycle magnetohydrodynamic generation

摘要

A method and apparatus for magnetohydrodynamic (MHD) generation of a combined-closed-cycle type using an MHD generator and a gas turbine-generator unit. A heater heats ooperative fluid to introduce the heated operative fluid into an MHD generator for power generation. The operative fluid is passed from the MHD generator to a compressor through a first portion of a heat exchanger. The compressed operative fluid is introduced from the compressor to a gas tubine-generator unit through a second portion of the heat exchanger, so that the gas turbine-generator unit generates power by the compressed operative fluid. The heat exchanger recovers heat energy of the operative fluid between the first and second portions thereof. After power generation, the operative fluid is returned to the heater form the turbine-generator unit to complete a combined-closed-cycle of the operative fluid.
