在使燃料能完全燃烧的情况下希望空气过剩系数越低越好。但过低可能造成燃烧不完全,而过高将增加了炉内空气量,降低炉子的热效率,对于强制通风或引风,还将增加动力消耗,烟气中的氧含量过多也将增加对炉管和其他部件的损失。

It is hoped that the higher the air surplus coefficient,推钢加热炉厂家, the better the fuel can be completely burned. But too low may cause incomplete combustion,推钢加热炉谁家好, and too high will increase the volume of air in the furnace and reduce the thermal efficiency of the furnace. For forced ventilation or induced draught, it will also increase power c***umption and excessive oxygen content in the flue gas will also increase the loss of furnace tubes and other components.








燃料气流直径的影响:气流直径越大,加热炉厂家,完全混合的时间越长。为了加速混合,可以将大股气流分成若干小股气流。这就是一些大功率的燃烧器有多个燃料气喷嘴的原因。



The effects of the diameter of fuel air airflow larger diameter,加热炉, the longer the complete mixing. In order to accelerate the mixing, the large strands of airflow can be divided into a number of ***all strands of air. This why some high-power burners h***e multiple fuel gas nozzles.


燃料气与空气的混合物在燃烧焰面法线方向的速度分量大于该混合物的火焰传播速度,则火焰被推出火孔,开始离焰,直到火焰被吹跑造成火焰熄火——脱火。燃烧器发生脱火是不允许的。

The velocity component of the mixture of fuel gas and air in the normal direction of combustion flame is larger than that of the mixture, and the flame is pushed out of the fire hole and starts to le***e the flame until the flame is blown away, causing the flame to go out. It is not allowed to remove fire from the burner.
