Facility scale (t/day)Basic Concept or Summary
Burnable refuse in the refuse
pit is incinerated with air
supply through the stoker-type
grate.
The steam boiler recovers heatfrom the high-temperature
generated gas of about 800
degrees.
Steam generated in the boiler
is sent to the steam turbine
and used to generate power.
The exhaust gas after heatrecovery is processed in theexhaust gas treatment facilities
to clear the environmental
standards. Then the gas isreleased to the atmosphere.
The incinerated refuse isdischarged as ash with
reduced volume in about 1/10of the original refuse and thenburied.

The Shinagawa Garbage Processing Plantof Tokyo not only generates power of
15,000kW but also supplies incineration
heat to more than 5,000 households in theneighboring Yashio Housing Complex
mainly for heating and boiling water.
