Mitsubishi Heavy Industries Environmental & Chemical Engineering Co (MHIEC) has been awarded a contract by the Clean Authority of Tokyo, to renovate core components at the Ariake waste-to-energy plant in Tokyo.
The contract for the refurbishment of stoker type incinerators will help to extend the service life and enhance energy efficiency of the waste-to-energy plant.
Valued at JPY3.2bn ($29.2m), the project is scheduled for completion in February 2020. The plant was designed and built by MHI, and concluded in December 1995.
It comprises two stoker incinerators each with capacity of 200 tpd, and can generate up to 5,600 kilowatts of electricity.
Under the contract, MHIEC will be responsible for the replacement and upgrading of superannuated components at the facility, such as equipment for refuse feeding, ash treatment, waste water treatment, draft fan, duct, and dust collection, as well as electric instrumentation and water supply systems.
Additionally, the project will also improve energy efficiency through the use of an exhaust gas treatment system, which includes MHIEC's technologies to lower power consumption by decreasing the load of bag filters, as well as the use of high-efficiency motors and inverters.
Once implemented, these measures will help to slash total annual CO2 emissions by more than 3%.
