System considerations of MHD by the utility

Magnetohydrodynamics (MHD) is described as a promising coal technology and is now attracting increasing attention, both in the government and private sectors. This paper describes the conceptual design process that led to a configuration maximizing the chances of success of the retrofit installation. Design options such as new versus existing steam generator, gas versus steam tie-in, oxygen enrichment versus separately-fired air preheaters are discussed. 3 refs
