Japan-headed Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC) has announced that it has received an order from Sagamihara City to refurbish core components of the 2.5 MWe Kita Waste-to-Energy (WtE) plant, a facility for incinerating municipal solid waste (MSW).
Japan-headed Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC) has announced that it has received an order from Sagamihara City to refurbish core components of the 2.5 MWe Kita Waste-to-Energy (WtE) plant, a facility for incinerating municipal solid waste (MSW).
According to a statement, the order calls for the refurbishment of three stoker type incinerators with a total waste treatment capacity of 450 tonnes per day (tpd) and a bulky waste shredder with a capacity of 85 tpd. The project will extend service life to 2036 and increase energy efficiency. The order is valued at JPY6.3 billion (≈ US$59 million) and is scheduled for completion in March 2021.
The 2.5 MWe Kita Incineration Plant was originally designed and built by MHI in 1991, consisting of a bulky waste treatment facility and MSW incineration plant. The plant’s three stoker type incinerators have each a capacity of 150 tpd.
The order covers replacement and upgrading of superannuated components including equipment for refuse feeding, incineration, combustion gas cooling, flue gas treatment, ventilation, ash handling and water supply, as well as electrical and other instrumentation.
Energy efficiency will be enhanced through the application of MHIEC’s proprietary ‘New Combustion Control System’, which contributes to stable combustion, as well as more efficient ventilation equipment, and high-efficiency motors and inverters. In addition, carbon dioxide (CO2) emissions will be reduced by approximately 10 percent annually by increasing the output of the steam turbine to 2.625 MWe.
