The objective of the present paper is to demonstrate availability of high performance coal-fired MHD-steam power plant. (1) Thermal efficiency of 50% can be obtained with 1, 000MW thermal input when 15m Faraday channel designed with up-to-date low temperature walls is used together with 1, 620K air heater. (2) Higher cycle efficiency of 55.5% can be obtained when the thermal input increases to 2, 000MW even when the MHD channel is designed with low temperature wall. (3) If higher temperature for air heater, 2, 100K and for channel wall, 2, 200K can be realized, very high cycle efficiency of 61.0% can be obtained.
