Abstract

In open cycle MHD generators operated by combustion gas, only thermal ionization in equilibrium is employed to make the gas conductive, where initial temperature of working gas must be over 3000°C and the efficiency, when combined with steam turbine generators, is expected to be approximately 55%. On the other hand, in closed cycle systems operated by monoatomic gas, it is possible to use nonequilibrium conduction by elevating only electron temperature and to reduce the initial temperature of gas, alleviating the difficulties of high temperature materials. On these considerations, discussions were made on the overall thermal efficiency of a relatively low temperature MHD generator combined with a given steam power plant in connection with the effects of operating parameters of MHD generator, and it was concluded that at the initial temperature of about 2000°C it is possible to get almost the same efficiency with that obtainable at a higher temperature.
