A power system for separating coal into clean and dirty coal and separately burning the fuel in different type combustors and combining the energy output

摘要

A power generating system for processing and converting low grade coal to electrical power comprises apparatus (14) for grinding a stream of coal into fine powder for separating the coal into high grade coal and low grade coal, a suspension burner (16) for burning the high grade coal, a recirculating combustor burner (22) for burning the low grade coal, and a combination of heat exchangers and turbines (20) for converting the heat energy to electrical power.
