Product Details

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.

SZL series water tube double drum steam boiler

1, This series double drum boiler is horizontal moving chain grate steam boiler

2,There is a steamwater separator and surface blow down device fixed in the upper drum, and a periodic

blow down device fixed in another drum which is at the bottom .

3, The tail decorates economizer

4, Reasonable water circulating system, large water content and steam space ensures good steam quality

5, boiler operate smoothly and have a potential for over load

6,Light chain traveling grate-type stoker and modulated speed control system make it easier to reach the best combustion

condition. Therefore, this boiler has good coal adaptability and high efficiency.
