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
