Title:
CO2回収型コージェネレーション・システム及びその運転制御方法
Document Type and Number:
Japanese Patent JP5372848
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized and highly efficient COrecovery type cogeneration system allowing CO-free cogeneration while separately recovering it without discharging COin an exhaust gas into the atmosphere.SOLUTION: A stratified air-fuel mixture consisting of pure oxygen or a mixture of the pure oxygen with a fuel at the center within a cylinder, and a circulating EGR gas on an outer peripheral part of the cylinder is burned to generate the exhaust gas consisting of only COand steam, and COis recovered at a high concentration by removing the steam while recovering heat by a heat exchanger. Downsizing and efficiency improvement of a device are promoted by directly using engine power in compression of the recovered CO.
