<p>A pressurized fluidized bed incinerator is equipped with: a pressurized fluidized bed incinerator (1); a supercharger (2) having a turbine (2a) and a compressor (2b); a fan (49_1) that supplies combustion air to the pressurized fluidized bed incinerator (1) when combustion begins in the pressurized fluidized bed incinerator (1); and a supercharger air bypass valve (CV3) that directs the air discharged by the fan (49_1) from the air inlet side to the air outlet side of the compressor (2b) when combustion begins in the pressurized fluidized bed incinerator (1), and that, after combustion has begun in the pressurized fluidized bed incinerator (1) and the pressure on the air outlet side exceeds the pressure on the air inlet side, circulates a portion of the combustion air (supplied from the compressor (2b) to the pressurized fluidized bed incinerator (1)) from the air outlet side to the air inlet side, in accordance with the pressure on the air outlet side.</p> |
