An Integrated Combined Cycle System using Coal Combustion and Gasification in a Pressurized Circulating Fluidized Bed Reactor

摘要

PURPOSE: A complex electric power generating system using combustion and gasification in pressure circulating fluidized bed is provided to simplify the whole process. CONSTITUTION: A system includes a descending pipe(42) moving gasified gas generated by pyrolysis and gasification of supplied fuel to a gas refiner(14); an ascending pipe(40) moving high pressure combustion gas generated by burning remaining char not gasified in the descending pipe to the gas refiner, and circulating remaining char not burnt to the descending pipe again; and a water cooled tube(46) generating hot steam using combustion heat generated in the ascending pipe, and moving to a high pressure steam turbine(24).
