Specifics of heat exchanger design for a 2000-MWt dual cycle, MHD Topping-Steam Bottoming power plant
Abstract
An MHD topping cycle puts extreme demands and premiums on the design of heat exchangers. Efficient transfer of energy is essential at temperatures far above those in conventional plants. In addition, the atmosphere is highly corrosive and very erosive with condensation and precipitation of seed and slag under reducing and oxidizing conditions. Caustic seed, as well as high concentrations of alkali and sulfur create an extremely severe test on MHD heat exchanger metal. The paper describes heat exchanger design considerations for a 2000-MWt input MHD Topping-Steam Bottoming open cycle plant and is based on use of Sub-Bituminous Rosebud Montana Coal with maximum drying (94 percent by weight of the total moisture is removed).
