Boiler Description

  CFBC technology, as a new type and matured high efficient, low-pollution and clean coal technology, it has many advantages that other combustion methods do not have.

  CFB is a low-temperature combustion, so the helium oxide is far lower than the pulverized coal furnace, only 200ppm approximately. At the same time, it is feasible to actualize direct desulfurizing during combustion, and it has high desulfurization efficiency. The technical equipment is economic and simple. The initial investment for desulfurization and performance cost is a far lower than that of PC+FCD.

  Extensive fuel adaptability and high combustion efficiency, especially suitable for low calorific value inferior coal.

  The exhausted cinder has better activeness, liable to actualize integrated utilization and free from secondary cinder pollution.

  Wide range for road adjustment, low load can be lower to 30% approximately of the rated load.

Features ofSHX series CFB steam boiler

High temperature cyclone separator:
High efficiency, wear resistance, separation efficiency≥98%,effectively improve the combustion efficiency of the boiler thermal efficiency.
Large furnace design:
Large furnace, low flow rate design, allow pipe technology decrease erosive wear.
Extend the residence time of coal particles in the hearth so that the coal can be fully burned.
Bell hood
Bell hood is used to avoid fuel returning to wind chamber while the air is evenly distributed.
Low bed pressure operation
Through optimizing the fuel particle, the operating bed pressure can be as low as 3500 Pa, which effectively saves operating costs and greatly reduces the production of NOx.
