An MHD Engineering Test Facility design concept is analyzed. A 500 MWt oxygen enriched MHD topping cycle integrated for combined cycle operation with a 400 MWe steam plant is evaluated. The MHD cycle uses Montana Rosebud coal and air enriched to 35 mole percent oxygen preheated to 1100/sup 0/F. The steam plant is a 2535 psia/1000/sup 0/F/1000/sup 0/F reheat recycle that was scaled down from the Gilbert/Commonwealth Reference Fossil Plant design series. Integration is accomplished by blending the steam generated in the MHD heat recovery system with steam generated by the partial firing of the steam plant boiler to provide the total flow requirement of the turbine. The major MHD and steam plant auxiliaries are driven by steam turbines. When the MHD cycle is taken out of service, the steam plant is capable of stand-alone operation at turbine design throttle flow. This operation requires the full firing of the steam plant boiler. The MHD compressors are steam turbine driven instead of electric motor driven which minimizes shifts in main steam turbine flow when operation changes from combined cycle to stand-alone service. A preliminary feasibility assessment is given, and results on the system thermodynamics, construction scheduling, and capital costs are presented. (WHK)
