无焰燃烧和扩散燃烧相比哪个更好

    燃气与空气的混合方式,对燃烧的强度、火焰长度和火焰温度都有很大的影响。根据混合方式不同,燃气的燃烧方法可分为三种:

    The mixing mode of gas and air has a great influence on the intensity of combustion, the length of flame and the temperature of flame. According to the different mixing methods, the combustion method of gas can be divided into three kinds:

    1、山东燃气锅炉无焰燃烧

    1 flameless combustion

    此种燃烧方式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。

    Such combustion means that the air required for combustion of the gas has been uniformly blended with the gas before combustion. The primary excess air factor is equal to the excess air coefficient during full combustion of the fuel, and no oxygen is obtained from the ambient air during combustion. When the mixture of gas and air reaches the burning zone, it can burn in an instant.

    2、扩散燃烧

    2, diffusion combustion

    此种燃烧方法即不预先混合,而是在燃气喷嘴口相互扩散,并燃烧。其优点烧烧稳定,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。

    The combustion method does not mix in advance, but is diffused and burned at the gas nozzle opening. The utility model has the advantages of stable burning, gas appliance has the advantages of simple structure, easy to produce but long flame, incomplete combustion, heating area of the carbide.

    3、预混部分空气燃烧

    3 premixed partial air combustion

    此种燃烧方式即燃烧前预先将一部分空气与燃气混合(一次空气过剩系数在0.2-0.8之间),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。

    This method of combustion, that is, before combustion, part of the air and gas mixture (primary air excess coefficient between 0.2-0.8), and then combustion. The utility model has the advantages of clear combustion flame, combustion intensification and high thermal efficiency. But the combustion is unstable, and the control of primary air and combustion components are required. Gas burner is more commonly used in this way of combustion.
