Progress in the application of biomass energy power generation technology at home and abroad

The Drax power plant is the largest thermal power plant in the UK with a capacity of 4 GW, including a 6×660.0 MW front and rear wall counter fired boiler. The biomass co-firing transformation project of the power plant started in the second half of 2008, and now six boilers are transformed into mixed-firing boilers equipped with biomass independent grinding, which is the largest biomass co-firing pulverized coal furnace power plant in the world. The power plant uses 1.5 million tons of biomass per year for mixed combustion, which can reduce CO by 22 million tons. After the completion of the transformation, it also has good economic benefits. In 2015, the total revenue of the power plant was £2.638 billion, of which the income from incentives and feed-in tariff subsidies for co-burning biomass was £451.8 million, accounting for 17.0% of the total revenue.

Finland Alholmens Kraft 550.0MW thermal power plant has the largest biomass and coal combined combustion capacity CFB unit in foreign countries, boiler evaporation capacity is 702 t/h, steam pressure is 16.5 MPa, steam temperature is 545℃, fuel is coal (10.0%), peat (45.0%), coal (10.0%). Forest waste (10.0%) and industrial waste wood (35.0%).
