Name of the Project
Matsumori waste-to-energy plant refurbishment.

Location
Mitagi Prefecture, Japan.

Project Owner/s
Sendai City (Miyagi Prefecture).

Project Description
The project entails the refurbishment of the Matsumori waste-to-energy plant, an incineration plant for municipal solid waste.

The project targets stable combustion and operation over the long term through replacing the plant’s ageing core components, including equipment involved in combustion, combustion gas cooling, flue gas treatment, waste heat recovery, ventilation and ash removal, as well as electrical instrumentation.

The contract calls for the renovation of the facility’s three stoker-type incinerators, capable of processing 600 t/d, to extend the plant’s service life and enhance its energy efficiency to reduce its carbon emissions.

The thermal efficiency of the boiler will be enhanced by replacing the steam-type soot blower, which removes dust adhering to the boiler pipes, with a pressure wave-type unit.

The adoption of high-efficiency electrical equipment, combined with optimised combustion control logic, enabled by upgrading the distributed control system, will reduce carbon emissions by more than 8% a year.
