Short installation period DZL Coal Fired Steam Hot Water Boiler with long service life
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.
Features and Advantages
1. Horizontal single drum water pipe chain grate boiler. Is composed of the upper body and lower grate boiler.
2. Longitudinal layout for single drum boiler body, boiler drum with two side water wall tube of the chamber radiation heating surface, regardless of the convective heating surface on both sides of the pipe bundle.
3. Drum internal thread smoke conection heating surface pipe fire tube, tube sheet with low stress without braced arch tube plate.
4. Chain grate points warehouse into the wind, the wind chamber air volume adjustment independently, grate stepless speed regulation.
5.Structure forms, can be combined in factory,also can be combined at the work site.
