Mitsubishi Heavy Industries Environmental & Chemical Engineering Co. (MHIEC) received an order from Kanazawa, Ishikawa Prefecture, to refurbish the core equipment of the city’s East Environmental Energy Centre, a municipal solid waste (MSW) incineration plant. The modification work calls for revamping of a stoker furnace type incinerator with a processing capacity of 250 tons per day (tpd), with the dual aims of extending the plant’s operational life and boosting its energy-saving capability. The refurbishing work is slated for completion in March 2017.
The newly ordered work is to consist of replacement and revamping of the plant’s core equipment, including facilities for waste heat utilisation, incineration, incinerator flue-gas cooling and waste gas treatment. MHIEC’s patented combustion control method, which contributes to stable combustion, reduces the volume of waste gas through high-temperature combustion technology and low-air-ratio operation, enables consumption of less energy. Energy is further conserved through the adoption of various high-efficiency motors. Together these features enable a greater than 8% (approx. 277 tons) reduction in carbon dioxide (CO2) emissions per year, contributing to curbing global warming.
