Mitsubishi Heavy Industries Environmental & Chemical Engineering Co. (MHIEC) has received an order from the City of Yokohama, Japan to rebuild the Hodogaya Waste Incinerator Plant.
The contract, which was awarded following a competitive bidding process, includes the dismantling and removal of the currently closed Hodogaya Plant and the construction of a new facility, with handover scheduled for March 2031.
The new waste-to-energy facility will consist of three stoker incinerators, each with a disposal capacity of 350 tons per day, for a total capacity of 1,050 tons per day.
The stokers to be used are V-type stoker waste incinerators developed by MHIEC to optimize the drying and combustion process. The plant will also use the heat energy generated during the incineration process to efficiently generate electricity.
According to MHIEC, the V-type stokers have an optimized stoker structure and incinerator shape, with the surface of the stoker directed toward the center of the flame during drying, combustion and post-combustion.
The main advantage of this design is the ability to efficiently utilize radiant heat during waste combustion, which contributes to more stable waste combustion and volume reduction, and reduces the proportion of unburned combustibles in the post-combustion ash (unburned waste), contributing to lower environmental impact.
