Steam Boiler / Coal-fired (biomass) steam, hot water boile

Steam Boiler

Coal-fired (biomass) steam, hot water boile

Main Features

The DZL series quick-installation boiler is a horizontal three-pass water pipe chain grate boiler.

Medium quality bituminous coal and anthracite coal. The boiler body is a single drum arranged longitudinally, and a screw is arranged inside the drum.

The patterned smoke tube forms the convection heating surface, and the drum and water-cooling walls on both sides form the furnace radiation heating surface.

Hot noodles. The combustion equipment adopts light chain grate; the whole unit is shipped from the factory in quick assembly form. Electrical control.

The system realizes stepless speed regulation of the grate, extreme parameter alarm and interlocking protection.
