MHD power generation is very expensive. We have to deal with very difficult concepts here. The origin of this type of power generation is Faraday’s theory of electromagnetic induction. The fields of both MHD and nuclear fusion depend on harnessing high temperatures and man has not yet shown progress in these fields. Now the MHD power generator is used as the aid for nuclear power generation, thanks to LMFBR. Modern MHD systems use dried and pulverized coal, with minimal ash content (below 20%). This coal is carefully injected at the input end through coal-injection equipment. Air is compressed and heated before being fed to the combustor utilizing heat in the exhaust gases of the MHD generator. MHD research oriented systems prefer argon and helium gases. But for large scale power production, this is not sufficient.
