电蒸汽锅炉厂家http://www.jnshengxin.cn/介绍说燃用发热量高的燃气，要使燃气能充分燃烧，需要大量的空气与之混合。电蒸汽锅炉的燃烧方法可归类为以下三种：
1、扩散燃烧即不预先混合，而是在燃气喷嘴口相互扩散，并燃烧。其优点燃烧稳定，燃具结构简单，但火焰较长，易产生不完全燃烧，使受热面积碳化。
Diffusion combustion that is not pre-mixed, but the mutual diffusion of the gas nozzle orifice, and burning. The advantage combustion stability, simple gas appliance structure, but the flame is longer, easy to produce incomplete combustion, heated area carbonation.
2、预混部分空气燃烧即燃烧前预先将一部分空气与燃气混合，然后进行燃烧。其优点是燃烧火焰清晰，燃烧强化，热效率高。但燃烧不稳定，对一次空气的控制及燃烧成分要求较高。燃气燃烧器一般多用此种燃烧方式。
That part of the air premixed combustion air prior to combustion in advance is mixed with a portion of the gas, and then combusted. The advantage is clear burning flame, burning strengthen, high thermal efficiency. But unstable combustion and combustion control components require a higher primary air. Gas burners generally burn more such manner.
3、无焰燃烧即燃气所需空气在燃烧之前已与燃气均匀混合。一次空气过剩系数等于燃料完全燃烧时的空气过剩系数，在燃烧过程中不需要从周围空气中取得氧气。当燃气与空气混合物达到燃烧区后能在瞬间燃烧完毕。
Flameless combustion air that is required prior to combustion gas has been uniformly mixed with the gas. Once the excess air coefficient is equal to the excess air ratio for complete combustion of the fuel required to obtain oxygen from the ambient air in the combustion process. When a mixture of gas and air to reach the combustion zone to burn is completed in an instant.
