Sumitomo Heavy Industries, Ltd. (Head Office: Shinagawa-ku, Tokyo; Representative Director, President, and CEO: Shinji Shimomura) secured an order from Tosoh Corporation (Representative Director, President: Mamoru Kuwada) for a 74 MW-class wood biomass and recycled fuel-fired boiler (planned construction site: Nanyo Complex, Shunan City, Yamaguchi Prefecture) based on the EPC (engineering, procurement and construction) contract.
This facility is a boiler for a biomass power plant toward energy decarbonization that is planned by Tosoh Corporation. It is a high-efficiency biomass-fired boiler that uses wood-based fuel as its primary fuel and employs the reheating system.*1 The type of boiler to be used—a circulating fluidized bed (CFB) boiler—has a large share of the high-efficiency biomass power plant sector. The SHI Group has supplied more than 530 CFB boilers in Japan and abroad.*2 Tosoh Corporation’s high regard for SHI’s delivery record and project proposal were leading factors in its decision to use a SHI CFB boiler in its project.
SHI will continue pursuing exceptional fuel diversity in CFB boiler technology and supplying high-efficiency power facilities with the aim of effectively utilizing resources and reducing environmental impact. SHI will contribute to the stable supply of electric power and utilities and the realization of a decarbonized society.
Boiler type: Circulating fluidized bed (CFB) boiler (reheating system)
Maximum evaporation: 270 t/h
Fuel type: Wood-based fuel, etc.
Scheduled start-up year: 2026
*1: Reheating system: A technology that makes high-efficiency power plant possible by sending steam that was expanded in a steam turbine back to the boiler, reheating it, and then sending it back to the steam turbine.
*2: SHI Group: Sumitomo Heavy Industries, Ltd. and Sumitomo SHI FW (SFW), a subsidiary. The figure provided includes CFB technology licensees of the SHI Group.
