This series of boilers is a typical double drums longitudinal "D" type package water-tube boiler. It consists of steam 

and waterdrum, membrane wall,superheater,convection bank and economizer.The burner is laid out at the front wall. When fuel 

has been burned inside of the furnace, the smoke goes through the superheater and economizer and finally goes to the 

chimney.This product is in compact structure, occupying less area and has good flame-overflow. It takes lower support to 

allow it could expand freely. Both the furnace water wall and convective duct  adopt membrane wall structure.This structure 

has good tightness and could effectively reduce the amount of fire bricks and maintenance load.The external packing uses 

colour steel plate with beautiful appearance. Its fully-automatic combustor has high burning efficiency and ignition control 

program. It also has over pressure and flameout protective functions. It takes package structure to shorten installation 

period.
