DZL-series new water-fire tube shell boiler

Product Description

1Efficient heat transfer component-threaded smoke tube is adopted after being couoled with reasonable dlow rate of flue gas,there can be hardly any dust stratifaction during running,that making thermal efficiency of boilers **8 oercent high than national standard.

2arched tube plate-threaded smoke tube turns the shell from quasi-rigid body to quasi-elastic body.after being coupled with reasonable winged flue,defects of high temperature tube plate cracking of traditional smoke and fire tubes can be fully avoided

3Bottom of the shell is free from flame radiation,so the possibility of bulge at the bottom of shell is eradicated.

4 Reasonable water circulation loop and unique backwater injection device increase the water speed in assending tube and explosion of water wall tube.

5Adoption of inertial isolation of smoke and dust within furnace,aftering being coupled  with effective multi-tube dust separator,dust emissio n concentration of boiler can meet demands of class 1 region.

6Reasonable boiler structure can support its own weight without the aid of steel frame.

7The use of energy-conserving and intensely radiating arch can strength the combustion,strong adaptability of coal types can ensure the stable and sufficient combustion of fuels.

8The adoption of high-standard and high-quality auxiliaries,accessories and automatic control equipment guarantees safety and steady operation.

9The structure is compact ,the boiler can be fixed up in single layer,and the floor area is small,so construction cost of boiler room is low,and the capacity-enlarging effect on the basis of origial boiler room is esspically obvious.
