Sumitomo Heavy Industries, Ltd. (Head office: Shinagawa-ku, Tokyo, Japan; Representative Director, President and CEO: Toshiro Watanabe; hereinafter referred to as “SHI”) completed the construction of a 74 MW-class woody biomass and recycled fuel-fired power boiler (hereinafter referred to as “the boiler”) for which it received an order from Tosoh Corporation (Head office: Chuo-ku, Tokyo, Japan; Representative Director, President: Mamoru Kuwada; hereinafter referred to as "Tosoh"), and delivered the boiler to Tosoh.

As the manufacturer of core pressure parts for this boiler, our company SHI FW Power Machinery Co., Ltd. ( Address: Jiangmen, Guangdong, China; hereinafter referred to as “SFWPM”) supplied Economizer, Furnace, WW Evap., Compact Separator, Convection Cage, PRH HDR & Coil, PRH Module, Intrex RH Module, PSH HDR & Coil, PSH Module, SSH HDR & Coil, SSH Module, Intrex SH Module, etc. Production ran from May 2023 to July 2024, and shipment was completed in July 2024. The boiler commenced operation in April 2026.

The boiler accommodates the use of a variety of fuels including construction waste-derived fuel and RPF(*1) in addition to woody biomass fuels such as white pellets.

In recent years, energy-intensive industries, including the chemical industry, have faced the critical challenge of addressing fuel procurement risks while also advancing decarbonization. The operation of the boiler is expected to contribute significantly to reducing the Tosoh Group’s CO2 emissions (*2) while simultaneously helping to stabilize fuel procurement and curb fuel conversion costs.

Power plants utilizing woody biomass and recycled fuels are leading decarbonization solutions capable of delivering benefits at an early stage, based on mature technology that has already been applied practically or commercialized.

The SHI Group has a delivery record of over 560 circulating fluidized bed (CFB) boilers within and outside Japan(*3), and holds a significant share of the high-efficiency biomass power generation market. SFWPM, as a key manufacturer within the Group, has supplied  pressure parts for numerous CFB boiler projects, contributing to this outstanding track record. Going forward, SHI will continue to contribute to the stable supply of electricity and utilities and to the realization of a decarbonized society by further enhancing the superior fuel flexibility of its CFB boiler technology and providing high-efficiency power plants that contribute to the effective use of resources and the reduction of environmental impact. SFWPM will remain committed to supporting these efforts with its high-quality pressure part manufacturing.
