摘要
Disclosed is a gaseous fossil fuel fired, indirectly heated, Brayton closed cycle comprising an alkali metal seeded noble gases that is rendered non-equilibrium, electrically conducting in a magnetohydrodynamic (MHD) electric power generator with zero emissions from the combustion products, including physical separation and sequestration of the carbon dioxide (CO2) what is emitted from the fossil fuel, with said cycle combined with a Rankine steam turbine bottoming cycle to compress the noble gas, while another optional new or existing Rankine steam cycle is placed in parallel and separate from the MHD cycle, and it is fired by the solid char remaining if the MHD cycle is fired with the devolatilized coal, and/or with solid coal culm, and/or unburned carbon in coal power plant waste ash, in order to achieve high efficiency at low capital, low operating, and low fuel costs.
