低氮燃烧器的工作原理

低氮燃烧器作为一种新型的燃烧技术而得到了广泛的应用,低氮燃烧,也就是低NOx燃烧技术是一种利用助燃空气的压头,把部分燃烧烟气吸回,进入燃烧器,与空气混合燃烧的技术。由于烟气再循环,燃烧烟气的热容量大,燃烧温度降低,独特新颖的喷嘴结构将天然气分割成数个小火焰,由于小火焰散热面积大,火焰温度较低,使热反应NO”有所下降。此外,火焰小缩短了氧、氮等气体在火焰中的停留时间,热反应NO”燃料NO”都有明显的抑制作用从而达到了NOx减少,也达到环保降本的作用。

Low nitrogen burner, as a new type of combustion technology, has been widely used. Low nitrogen combustion, that is, low NOx combustion technology, is a technology that uses the pressure head of combustion air to absorb part of the combustion gas, enter the burner and mix with the air. Because of the gas recirculation, the heat capacity of the flue gas is large and the combustion temperature is reduced. The unique and novel nozzle structure divides natural gas into several small flames. Because of the large heat dissipation area and low flame temperature, the "thermal reaction NO" has been reduced. In addition, the flame shortens the retention time of oxygen and nitrogen in the flame, and has obvious inhibitory effect on the "thermal reaction NO" and "fuel NO", thus achieving the decrease of NOx and the effect of environmental reduction.


低氮燃烧器的工作原理


因为燃气的有害燃烧产物主要组成为NOx、CO,减少有害排放的主要途径是减少NOx的排放。北京创为机电设备有限公司的燃烧器厂研发出的燃气燃烧器金属纤维燃烧头技术应用功率从5kW40,000kW,保证了低氮氧化合物的排放。北京创为的分体式低氮燃烧器燃烧器装上带低氮氧排放的金属纤维燃烧火管。利用烟气内循环燃烧头技术应用到中心回焰式锅炉上,并且采用了一种称之为自由火焰的燃烧头技术应用到三回程的锅炉上,有效地并且大大降低燃烧器的NOx排放有害物质和控制值范围 。如果对于低氮燃烧器还有什么问题就可以直接联系我们北京创为机电设备有限公司。

Because the harmful combustion products of gas are mainly composed of NOx and CO, the main way to reduce harmful emissions is to reduce NOx emissions. The technical application power of the combustion head of the gas burner of the combustor of Beijing created by the combustor plant of the mechanical and Electrical Equipment Co., Ltd. is from 5kW to 40000kW, which ensures the emission of low nitrogen and oxygen compounds. A separate low nitrogen burner burner in Beijing is equipped with a metal fiber combustion burner with low nitrogen and oxygen emissions. The internal circulation combustion head technology is applied to the central back flame boiler, and a combustion head technology called free flame is applied to the boiler of the three return, which effectively and greatly reduces the NOx emission of the combustor and the range of the control value. If there are any problems with low nitrogen burner, we can directly contact our Beijing Chuangwei Electromechanical Equipment Co., Ltd.
