PURPOSE: To feed combustibles dusts as well as raw waste materials and sewage discharged from a city region to each of processing plants, recycle energy gener ated when each of the processing plants performs the processing to the city region, perform the energy recycling operation and make an effective utilization of it.
CONSTITUTION: Digestive gas is generated with a digestive gas generating plant from the raw garbages and sewage muds discharged from city regions. Combustible dusts discharged from the city regions are ignited with a dust combustion boiler of a dust incineration and power generating plant so as to produce steam. The digestive gas is used for igniting dusts and as driving fuel for a gas turbine of a power generating plant. Combustion discharged gas from the gas turbine is injected and guided to an over-heater. The combustion discharging gas of high temperature of the gas turbine is fed out to the super heater, the steam from the dust incineration boiler is converted into an super heated steam and the steam turbine is driven by a super heated steam.
