  DZL steam boiler is composed of 2 main components: the upper assembled component is the body heat accepting part, and the lower assembled component is of combustion equipment. The former part of the boiler body is arranged as water cooling wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace; it's rear part is arranged with dense convection pipe bundle between upper and lower boiler cylinders; 

  DZL steam boiler high temperature smog after combustion shall stand for twice returning flushing transversely to the heat accepting surfaces, and shall be introduced to coal saver singly arranged, and flow into duster and exhausted from chimney in the end, The 20t/h assembled water pipe boiler is composed of front furnace, rear furnace, convection pipe bundle, coal saver and chain grating, and which are assembled in big components respectively for delivery.

1.  DZL steam boiler the overall structure is compact and reasonable, structure and the water cycle is clear and simple , small footprint, elegant, less investment in civil works. 
2.  DZL steam boiler is easy to operate, smooth running, fast boost heating, adequate effort, adapt to many kinds of fuel.
3.  DZL steam boiler feed water and coal, grate run, slag remove, fans self-control, over-pressure, high or low water (steam boiler) is chain protection to ensure the safe operation of the boiler. 
4.  DZL steam boiler front and rear arch is reasonable and form a strong radiation arch to enhanced combustion, maximizing fuel adaptability.  

5.  DZL steam boiler arranges adequate heating surface to ensure a reasonable exhaust gas temperature, improve the thermal efficiency of the boiler.
