Name of the Project
Kita incineration plant rebuild.

Location
Kita City, in Tokyo, Japan.

Project Owner/s
Clean Authority of Tokyo.

Project Description
The Kita municipal solid waste incineration plant, with a disposal capacity of 600 t/d, has been in operation since 1998 and has become superannuated.

The project involves the rebuild of the plant.

The new plant will comprise two stoker incinerators, each with a disposal capacity of 300 t/d, and a power generation equipment.

The plant will also incorporate high-efficiency power generation using heat energy produced during the incineration process, and provide excess heat for nearby city facilities.

The V-type stokers to be installed have an optimised stoker structure and incinerator shape, with the surface of the stoker directed at the centre of the flame during drying, combustion and post-combustion.

The main benefits of this design are the efficient use of radiant heat, as the waste is combusted, helping to stably burn and reduce the volume of waste, which varies in terms of characteristics and conditions; and the reduced proportion of unburned combustibles in the post-combustion ash (unburned waste), contributing to a lower environmental load.
