DZL (SZL) horizontal coal-fired steam boiler
The boiler is a single-drum/double-drum longitudinally-arranged water tube type saturated steam boiler. The boiler is designed for bituminous coal, and the combustion device is a chain-and-link grate, which realizes mechanical coal addition. It is equipped with a blower, induced draft fan, and dust removal device to achieve mechanized ventilation.

Model:

Rated working pressure:

Rated steam temp.

Applicable fuel: General anthracite, lean coal, bituminous coal, slag bituminous coal, low-grade bituminous coal, general lignite, high-moist lignite.

Different types of coal are equipped with different burners and furnace structures. Please consult our professopnal sales personnel for specific information.


45.png  Compact structureThe length of the front and back shaft is longer than the other ones, which prolongs the time of fuel combustion in the furnace and lower the carbon content in the furnace slag. Thus, the overload ability of the boiler is strengthened with the increased effect area of furnace grate.
