    Abstract: A device for converting a fuel including solid components, known as a solid fuel, into a gaseous fuel, includes a pyrolysis zone (2) for pyrolyzing solid fuel, having pyrolysis elements that are capable of decomposing the solid fuel into a pyrolysis gas and into a solid pyrolysis residue, known as coke, and a combustion zone (3), which is distinct from the pyrolysis zone (2), for burning the pyrolysis gas and having combustion elements (31, 32, 33). The device also includes elements for circulating pyrolysis gas from the pyrolysis zone (2) to the combustion zone (3), which is surrounded by the pyrolysis zone (2).

    Abstract: 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.
