POWER GENERATING SYSTEM USING LOW QUALITY COAL

摘要

A power generating system (A) using low quality coal is provided with: a low quality coal upgrading plant (3) for heating and upgrading low quality coal (2) to high quality coal (4); a CO2 capture plant (6) for recovering CO2 from exhaust gas (7) generated by upgrading the low quality coal (2) in the low quality coal upgrading plant (3), while using steam (8) generated from upgrading the low quality coal (2) in the low quality coal upgrading plant (3); and a power plant (5) for generating power using, as fuel, the high quality coal (4) obtained by upgrading the low quality coal (2) in the low quality coal upgrading plant (3).
