摘要: A fluidized bed gasification furnace has a fluidized bed formed and a freeboard section F above a bed material so as to produce a produced gas by a reaction of raw material with a gasifying agent and take out the produced gas through the freeboard section. Upon shutdown of the furnace, inert gas is fed from below to the furnace for purging of gas in the fluidized bed with inert gas while steam is supplied to a freeboard section above the fluidized bed to purge a gas in the freeboard section with steam.

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.

摘要: A gasification furnace 2 is divided into a plurality of gasification furnace units 2a and 2b each of which has an inlet 15a, 15b on a lower portion at a longitudinally upstream end in a direction of travel of raw and bed materials and has an outlet 16a, 16b on an upper portion at a longitudinally downstream end in the direction of travel. The outlet 16a is connected to the inlet 15b. The inlet 15a is fed with a raw material and a hot bed material from a materials separator 8. The inlet 15b is also fed with the hot bed material from the material separator 8. The outlet 16b is connected to a combustion furnace 5.
