Coal fired hot water boiler
Our coal fired boiler adopt double drum water tube structure, evaporation capacity is bigger than normal design boiler. Special patent technology increase working efficiency and reduce emission.

Product introduction

Overview:

Our coal fired boiler adopt double drum water tube structure, evaporation capacity is bigger than normal design boiler. Special patent technology increase working efficiency and reduce emission.

Benefit:

1.Double drum design, water tube structure, heating area is 10% more than other same kind products. Output capacity is much stronger than others.

2.The fire chamber has a special design—cyclone re-burning chamber, which reduce the dust content of emission and make the carbon black powder burning completely. It will increase the boiler efficiency and reduce the concentration of emission.

3.Compact structure, reliable operation and longer service life.

4.The grate use small roller structure and boundary grate technology, which Improving the reliability of operation.

5.Use patent technology: closed type wind chamber and double side grate air-adjusting device. Use conical surface sealing structure which is processed by machinery, it increases the sensitivity of the grate’s air-adjusting.

Construction:

Boiler adopts double drum water tube structure, horizontal type construction. The Fire chamber has a special design—cyclone re-burning chamber. Use closed type wind chamber and double side grate air-adjusting device to increase evaporation capacity.
