Product Details

Tong Hai Power the pioneer industrial boilers of China market, and we have various boilers for worldwide customers.

Coal fired chain grate steam boiler:

1.The boiler adopt single drum, monolayer arrangement, compact structure, sufficient output, safe and reliable operation, short construction period, and low installation cost ect.

2.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 result, the gas emission concentration shall meet the requirements of grade A environmental protection area.

3.The grate employ the technology patent of small roller structure, boundary grate and so on, improving the operation reliability of the boiler.

4.Since the adoption of technology patent for the sealed wind chamber and bilateral grate air register, and the application of machining cone seal structure to grate adjusting air equipment, the sensitivity of the grate shall be improved.

5.According to the customers' requirements, other energy saving equipment, shall be matched.

Horizontal automatic coal fired steam boiler main purpose is to provide high quality steam and motive power for industrial production, such as textile, papermaking, rubber, food, hospital and other industries.

Compared with the other domestic capacity products ,we have the advantages of reasonable and compact structure and low steel consumption.
