Automatic Control DZL Coal Fired Steam Hot Water Boiler Wide adaptability of coal
production
HD DZL series steam and hot-water boiler is the single-cylinder, water-tube assembly, chain grate boiler. Boiler drum is arranged along the center of the boiler longitudinally.
The front drum and both sides of the furnace water-wall tubes form radiant heating surface, the rear drum and the tube nest between the header form convection heating surface.
Coal economizer is installed at the rear of boiler.
After some heat of the combustion-generated high temperature fume is absorbed by the hearth, the fume flows to the convection heating surface through burn out chamber and exhausts outside through the chimney via coal economizer, dust collector and draught fan.
