Driven by national environment-friendly policy, the boiler industry is facing with transformation in which the traditional boilers are prohibited because of its high pollution and consumption. With such background , the gas fired steam boiler become the winner in the market.



The good market performance of the gas fired boiler not only benefit from the transformation but also from its own advantages including high heating efficiency, high workload, strong adaptability, high automatic level and popularization of the gas. During the boiler’s running, its ventilation system can discharge the waste smoke to improve the combustion efficiency. natural ventilation

Natural ventilation takes advantage of the natural ventilation pressure head generated from density difference between the chimney smoke’s and the outside air’s to overcome the flow resistance to improve the combustion efficiency. Mechanical ventilation

Mechanical ventilation of gas fired steam boiler depends on the pressure head produced by the machine to overcome the air duct resistance. This method can be divided into three types : negative pressure ventilation, positive pressure ventilation and balance ventilation. The difference of them lies in the different induced draft fan.

The continuous service life of the gas fired boiler is more than 10 years. The radiant heating area of the boiler is corrugated furnace while the conversion heating area adopts threaded smoke pipe which can enlarge the heating area, improve the heating efficiency to 92%, higher than national standard.
