Features:
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 shorten the installation period and reduce 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
