130TPH CFB Biomass Boiler features:

  • The combustion temperature of furnace is about 750°C, which can effectively prevent fluidization failure due to low-temperature bonding of alkali metal-containing bed material.
  • High-efficiency cyclone separator ensures stable steam parameters; direct-push biomass feeding from dense phase area at lower part of furnace.
  • Tail flue duct is in a “curved” shape, which can prevent blockage by bonding materials and solve ash accumulation. The air preheater adopts enamel tube structure to reduce HCI corrosion in flue gas.
  • The boiler adopts natural circulation, single-drum, open-air layout, centralized large-diameter downcomer, and full-membrane wall suspended closed structure.

130TPH CFB Biomass Boiler Runs Well In Hunan Province

Introduction to the 130TPH CFB Biomass Boiler User

Power plant boiler manufacturer Taishan Group won a 130TPH biomass CFB Boiler project in July 2020. Now the boiler has been running smoothly for over one year; steam output is 137t/h, and NOx emission value is 40mg/m3. The final user is Hunan Juntai New Material Technology Co., Ltd. It is a large-scale state-owned high-tech enterprise integrating cellulose manufacturing and sales, power and heat production and supply. In September 2010, it joined China Paper Investment Co., Ltd. The company covers an area of about 2,000 mu, with total assets of 4.35 billion Yuan and 580 employees. It has a 300,000 tons/year cellulose production line, and is the largest coniferous cellulose production base in China. The enterprise has won many honorary titles like “High-tech Enterprise in Hunan Province”, and “Leading Enterprise of Forestry and Agricultural Industrialization in Hunan Province”.
