Mitsubishi Power | Boilers
A wide range of biomass mixed co-firing rates can be realized by applying coal/biomass dual system (coal pulverizer/burner) to coal-fired power generation technologies. Biomass co-firing rates can be adjusted without major changes of equipment. In addition, it is possible to have biomass firing in a boiler by adding a small amount of coal ash.
