Abstract
A power generating system for processing and converting low grade coal to electrical power comprises apparatus for grinding a stream of coal into fine powder, separating the coal into high grade coal and low grade coal, a suspension burner for burning the high grade coal and generating heat for powering a gas turbine, a circulating fluidized burner for burning the low grade coal for generating heat, and a combination of heat exchangers combining a portion of the heat from the suspension burner with the heat from the circulating bed burner for generating steam for powering a steam turbine.
