摘要:
A waste treatment facility 100 is constructed in vicinity of a cement production facility 200. This comprises: a gasification furnace 1 for gasifying waste to generate a pyrolysis gas; and a gas transport line 6 for transporting the pyrolysis gas generated in the gasification furnace 1 to a calciner 20 or the like in the cement production facility 200 while containing entrained char and ash, The flow rate of the pyrolysis gas from the gasification furnace 1 is limited to a level below a predetermined flow rate ratio over the flow rate of the exhaust gas from the calciner 20 to reduce the fluctuation of the temperature in the calciner 20, so that the stability in the operation of the cement production facility 200 is ensured. The pyrolysis gas may be introduced to the calciner 20 from the gas transport line 6 so as to swirl along the peripheral wall section 23.

摘要:
In a fluidized bed type gasification furnace 1 for thermally decomposing wastes, a temperature of a fluidized bed 1a is maintained within a preferable range, even if the wastes containing a dewatered sludge having higher water content than the conventional wastes is processed. A waste treatment facility 100 is constructed in vicinity of a cement production facility 200. The apparatus comprises the fluidized bed type gasification furnace 1 for gasifying the wastes to generate a pyrolysis gas, and a gas transport line 6 for transporting the generated pyrolysis gas with entrained char and ash to a preheater 10 or a calciner 20 for cement. The apparatus also comprises a temperature elevating device such as a gas air heater 41 and the like, which elevates the temperature of the estimated value that is supplied to the gasification furnace 1 by utilizing waste heat of the cement production facility 200
