Crucial and limiting engineering and naterials problems associated with the design of an MHD steam bottoming plant are discussed. Existing experimental and theoretical results ori corrosion, fouling and deposits, potassium seed recovery and regeneration, are reviewed. The state of knowledge regarding the design of heat recovery and seed recovery units for coal-fired MHD plants is inadequate at the present time. nones ^ fORTIONS OF THIg_gEPOgT^RE ILLEGIBLE.
