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.

boiler body and auxiliaries:

product introduce:

1,The DZL series quickly installed steam boiler is the most advanced water-fire tube boiler in Chinese market, with high efficiency, small in size and long working life for 20 years.

2,The boiler after improvement takes use of structure of wing type smoke duct, one-way screwed smoke tube, arched tube plate, smoke and gas separation room and several other advanced technolog, which has increased the water circulation speed and safety factor.

3,This boiler series is well designed, compact structure, quickly installed, monolayer arrangement, so that the civil engineering and investment could be saved. These improvement ha extend boiler's working life and make it the national energy saving product.
