Product Description

Our coal fired boiler includes DZL type boiler, SZL type boiler.
DZL boiler has steam boiler from 1t to 60t/h and hot water boiler from 0.7 to 42MW.
Single drum, threaded line pipe, chain grate, fire tube, assembled boiler.
SZL boiler has steam boiler from 2t to 20t/h and hot water boiler from 1.4 to14MW.
Double drums, water tube, chain grate, assembled bolier, or divided into upper and lower parts.

1) New DZL fire tube-water tube shell type boiler
2) Reasonable heat surface and burning device, heat efficiency is 4~5% higher than national standard
3) Reasonable flue speed design, heating surface without scattered ash and no abration
4) The boilers can work full load, high efficiently and safely in long term

5) The big and tall boiler furnace can be easily designed according to the different fuel to improve the  

    burning rate of fuel   and reduce black smoke

6) Adopt single return design and injected circulation design for the hot water boilers, the medium speed 

    in return of heat surface is higher than national standard

7) Adopt big and high strength grate (below 20T), adopt squama type or beam type of traveling grate 

   (above 20T), which improve the boilers' safety and lessen the leaked coal and adjust burning conveniently.

8) Scoot idiomatically separated at the exit of boiler furnace which can reduce dust content and lessen abrasion 

    of back heat surface

9) Compact structure, 3~5meters lower than other style boilers' installation height, which shortens the installation 

    period and reduces the cost of boiler house

10) Closed scoot cleaning avoid the second pollution and save time and labor
11) Big volume benefits power-off protection, high ability suitable for load waving.
