This series boiler has a D-shaped arrangement and a package structure. It leaves the factory in a complete form. The water cooling wall in the hearth adopts densely arranged structure with good sealing feature and is suitable for micro-negative pressure burning. The series boiler consists of upper and lower barrels,super-heater,hearth,water cooling wall,convetion tubes and coal economizer. The burner is arranged at the front wall and flame is heat-exchanged of radiation when it passes through the hearth,turns left at the rear part of the hearth and runs forward to pass throug the super-heater and the convection tubes to have heat exchanger of convection. At last it runs through the smoke channel and the coal economizer and is exhausted out via the chimney.
This type of boiler has advantages of high efficiency,fast temperature rising,safe and reliable operating,small volume,light weightand short assembling period. In addition to the coal economizer and the double water pipes structure.It has high heat efficiency,fast pressure rising,full automatic burning,stable and reliable characteristic.
This series full-automatic boiler adopts horizontal three return course wet back structure.
The internal furnace adopts the most advaned structure-the corrugated furnace to increase the heat transfer area of the internal furnace as well as its stabliblity and to ensure safety and reliability of the boiler
The explosion-proof door which has functions of explosion-proof,fire watching and machine is arranged behind the boiler.
