Valmet to supply multifuel boiler to Japan power plant

Valmet will provide a multifuel boiler and flue gas cleaning system to a 112-MW power station being built plant in Kushiro, Hokkaido, Japan, the company announced March 9.

The advanced circulating fluidized bed (CFB) boiler will be capable of cofiring coal and biomass, including wood pellets and crushed palm kernel shells. Valmet’s CFB design, dubbed “CYMIC,” is capable of burning 100 percent coal or biomass, or any ratio in between.

Thermal power of the boiler will be 265 MWth, and the electric production capacity of power plant will be 112 MWe. Emission control will be ensured by NOx-reduction system and bag house filter, according to Valmet.

Jouini Koskinen, Valmet senior sales manager of energy sales, AP Japan, pointed to Japan’s investment in renewing its power production assets, and commented that the market there is very good for fluidized bed technology, considering the country’s increased focus on bioenergy and need for fuel flexibility.

Installation works are planned for 2018, with commissioning and start-up in the second half of 2019

The Kushiro plant marks Valmet’s second project with Japanese partner JFE Engineering. In November 2016, the companies unveiled a project at MPM Oji Eco Energy Corp.’s Mitsubishi Paper Mills Ltd. plant in Hachinohe city, Aomori prefecture, Japan. There, Valmet is supplying a biomass-fired 75 MWe CYMIC boiler and flue gas cleaning system. All the electricity generated at the plant will be supplied to the grid and benefit from Japan’s feed-in-tariff.
