摘要： PURPOSE: To prevent the generation of the local heating of the equipment at the rear stage of a pressurized fluidized bed boiler and the breakage by the thermal stress of the equipment by providing a unburnt combustibles burning part to burn the unburnt combustibles in the combustion gas between a combustion gas outlet of the pressurized fluidized bed boiler and a dust removing equipment. CONSTITUTION: An unburnt combustibles burning part 11 to burn the unburnt combustibles in the combustion gas 45a is provided between a pressurized fluidized bed type boiler 2 and a dust removing equipment 24. The inner wall of the unburnt combustibles burning part 11 is heated with the high temperature gas generated by burning the propane gas 49 with the help of the air 50a to re-heat the combustion gas 45a brought into contact with the inner wall. In addition, oxygen 51 is fed as the oxidizing agent to burn the unburnt combustibles. The combustion gas 45b whose unburnt combustibles are re-heated is >=99% in the combustion efficiency at the outlet. This gas is passed through a cyclone 25 and a high temperature filter 31 constituting a dust removing equipment, and the ash of 10 micron in grain size is successively removed by the equipment of each dust removing equipment in the order of the larger grain size.

CONSTITUTION:Collected garbage is supplied to a garbage pit 1 from a garbage loading port 12 and temporarily stored therein until it is burnt in an incinerator 1. Then, the garbage is sequentially thrown into the incinerator 2 by a garbage crane 10 and a bucket 11 and burnt. The burnt ash 21 is collected in the lower part of the incinerator 2. Combustion gas 28 is guided to a boiler 3 to generate steam and the steam is guided to a steam turbine 7 to generate electricity by a generator 8. The steam flowing out of the steam turbine 7 is returned to the boiler 3 through a condenser 9 and reused. This return steam is fed to the garbage pit 1 to be directly heat exchanged with the garbage. Further. the combustion gas 28 is exhausted as combustion exhaust gas 29 from a funnel 5, so that a system can be effectively employed.
