    摘要: Upon cold startup of a gasification facility, a fluidized air 10 is supplied to a combustion furnace 9 to fluidize a combustion-furnace fluidized bed 11 while a preheating fuel 22 is supplied to the combustion furnace to preheat the fluidized bed 11 up to an autoignition temperature of coal. Then, a coal 23 is charged to the combustion furnace 9 to heat the fluidized bed 11 and bed material is circulated between the combustion and gasification furnaces 9 and 1 for heating. Upon startup and shutdown of the gasification facility, steam 2 from an exhaust heat recovery boiler 20 in heat exchange with an exhaust gas 15 from the combustion furnace 9 is supplied to the gasification furnace 1 to purge the gasification furnace 1 and a lead-out passage 6 with the steam 2 utilizing the exhaust heat.
