Bozzuto, C R

An atmospheric pressure coal gasifier is combined with an MHD generator and a vapor generator to provide an entirely coal-fueled power generating system. The combustible low btu gas formed in the gasifier is passed through a gas cleaner wherein particulate matter, gaseous sulfur compounds, and char are removed to produce a clean combustible low btu gas. A first portion of the clean combustible low btu gas and the char are passed to the burner of the MHD generator as a source of fuel. A second portion of the clean combustible low btu gas is passed to a direct-fired air heater as a source of fuel for preheating the combustion air supplied to the burner of the mhd generator.
