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.
