Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC), a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), has recently received its first order for a newly developed energy-independent sludge incinerator consisting of a binary power generation system* incorporated into a conventional sludge incinerator. This configuration enables the incineration equipment’s power needs to be met entirely through the use of waste heat. The order was placed by the Tokyo Metropolitan Government’s Bureau of Sewerage, which provided the technical certification for the system. Plans call for the new incinerator, which has a processing capacity of 250 tons per day (tpd), to be completed by March 2020 at the Shingashi Water Reclamation Center in Itabashi-ku, Tokyo. Widespread adoption of this innovative apparatus going forward is expected to contribute significantly to energy savings and the curbing of global warming.
The newly received order represents phase 2 of a project to reconfigure the sludge incineration facilities at the Shingashi Water Reclamation Center. The new incinerator will be built to replace the existing, outdated incineration equipment. Besides the incinerator and power generation system, the order also calls for installation of equipment relating to dewatered sludge supply, heat exchange, ash treatment, white plume prevention and flue-gas treatment.
