Valmet to deliver boiler, equipment to biomass plant in Japan

By Erin Voegele | June 08, 2018

On June 7, Valmet announced it will supply a biomass-fired 75 MWe CFB boiler and flue gas cleaning system to Air Water & Energia Power Onahama Corp.’s Onahama Plant in Japan. The plant will be primarily fueled by wood pellets and palm kernel shells and produce more than 5 million kWh of electricity annually.

According to Valmet, the new CFB boiler will enable the power plant to achieve a stable power supply at high thermal efficiency while significantly reducing carbon dioxide emissions. This order is the fifth received by Valmet in recent years for delivery of a CFB boiler to the Japanese market.

"High combustion efficiency in Valmet's CYMIC boiler will be achieved due to good mixing and long char residence time,” said Kai Janhunen, vice president, energy business unit, Valmet. “It is also important to have high steam parameters available for demanding fuels, like agro-based biomass, in order to meet the high expectations for boiler efficiency.”

Installation work is scheduled to begin in 2019, with commercial operations expected to commence during the first half of 2021.

The project will be delivered in cooperation with Japan-based JFE Engineering Corp., which is the EPC contractor for the Onahama biomass power plant.
