Product Description

35t/h-130t/h Sequence Chain Grate Boiler,Coal Fired Chain Grate Stoker Boiler

 

35-ton to 130-ton sequence chain grate boiler

 

Product features

1. The boiler shall be employed monolayer arrangement.featuring the following advantages:compact structure,easy installation and operation, and low cost of boiler room,which shall economize more than 40 per cent on investment of boiler house.

2. The design of natural circulation convective heating surface for the boiler resulted in sufficient outgas, low accident rate, and safe and reliable operation.

3. The design of cyclone reburning chamber in furnace resulted in the decrease of dust contained in the flue gas. At the same time, incandescent carbon black particles shall burn further, enhancing the boiler thermal efficiency, and decreasing gas blackness, as a ash particle of the flue gas emission concentration shall meet the requirements of grade A environmental protection area. The bigger diameter contained in the flue gas from convection bank, reducing the eronsion of convection heating surface, and improving the boiler life.

4. The grate shall use the technology patent of scale-type fire bars, boundary grate and so on, improving the operation reliability of the boiler.

5. Because of the sealed wind chamber, entering wind by both sides, and the application of machining cone seal structure to grate air register, the sensitivity of the grate shall be improved, which is national protected technology patent.

6. According to the customers’ requirements, the layering burn device and other energy saving equipment,implemented in state, shall be matched.
