Coal Fired CFB Hot Water Boiler Introduction

High temperature cyclone separator

High efficiency, wear resistance, separation efficiency ≥ 98%, effectively improve the combustion efficiency of the boiler thermal efficiency.

 

Large furnace design

  1. Large furnace, low velocity design; the application of wearproof tube technology, reducing erosive abrasion;
  2. Extend the residence time of coal particles in the furnace so that the coal can be fully burned.

 

Bell jar type hood

Adopt bell type hood to distribute air averagely and avoid fuel reverse to wind chamber.

 

Low bed pressure operation

By particle optimization, the operating bed pressure can be decreased to 3500 Pa, which effectively saves operating costs and greatly reduces the oxynitride generated.
