Detailed Description
Capacity:0.5t/h-4t/h  0.35mw/h -2.8mw/h
Pressure:0.7Mpa-2.5Mpa
Fuel: Coal, wood, Biomass pellet, Rice Husk, Bagasse, etc. 
New DZH type steam boiler is single drum vertical type fire tube shell boilers. Moving grate combustion equipment. Right and left sides of the furnace water wall radiation heating surface, wings and drum inside the flue pipe thread for the convection heating surface. Front and rear sides of the furnace wall and water wall outside a brick masonry. The boiler uses arched tube plate, threaded pope and problems. Burning fuel into the combustion chamber in the grate, the production of gas along the bottom of the drum in the interval through a wall of smoke into the mouth of the wings convection tube, smoke box to enter through the front threaded pipe, after the dust collector, cited by the induced draft fan pumped into the atmosphere through the chimney.
 
The technical characteristics:
1. Uses arched tube plate and threaded pipe composed of drum, so that the drum by a quasi-rigid body structure of the quasi-elastic body, eliminating the tube plate area bracing pieces, reducing stress. Tube sheet smoke tube consists of two return to single return, to solve the problem of rube sheet cracks.
2. The boiler drum lower because the layout some increase in pipeline of row, the bottom of the drum to eliminate water dead zones, the deposition of sludge is not easy, drum to get good high temperature cooling, prevented the lower drum kits.
3. Efficient heat transfer pipe thread, obtain an enhanced heat transfer effect, reaches the boiler temperature rise, the pressure rise characteristics of fast, improve the thermal efficiency of the boiler.
4. Boiler compact, compared with the same type of boiler, outside of the smal size, saving boiler room investment in infrastructure
5. Boiler operation and stability, easy adjustment, high effectiveness, with 110% overload capability.
6. Using threaded pipe heat transfer, improved heat transfer coefficient and thermal efficiency, since the flue gas in the rube with disturbance. Tobacco pipe hard fouling, play a role in self-cleaning.
7. The shape furnace of Chinese eight-shaped wall, there is a certain portion of export smokestack dust effect. The boiler of the original dust concentrations at below standard. Ensure the boiler soot emissions targets to meet national environmental regulations.
