High thermal efficiency SZL Coal Fired Steam Hot Water Boiler wiht
long service life
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. Compact structure, small installation space, single-floor boiler
room, cost-effective infrastructure.
2. Great assembly level, short installation period and inexpensive
3. Sufficient and reasonable heating surface, quick
temperature/pressure-rise of boiler, satisfactory productivity and
high heating efficiency.
4. Introduce the air with air distribution chambers of grate. All
chambers can adjust the air flow independently and grate can be
regulated step-less speed.
5. Wide range of applicable coals and full combustion.
6. Electric control cabinet is equipped with complete automatic
control and monitor
instruments featuring high automation, safety, reliability and
