引射式平焰烧嘴是一种新型节能装置。它综合了鼓风平焰烧嘴和引射式直焰烧嘴的优点,具有炉子升温速度快、炉温均匀、节能、不鼓风、空煤气比调等一系列优点。我国现有大量工业炉仍采用引射式直焰烧嘴,如改用这种引射式平焰烧嘴,可在不增设鼓风机的条件下,利用原有的高压煤气实现平火焰加热。因此,从我国国情出发,研制引射式平焰烧嘴对提高工业炉技术装备水平、节约能源具有重要的现实意一、烧嘴结构及原理烧嘴由引射器和旋流器组成,结构示意见图1。
Buried flame burner is a new type of energy-saving device. It combines the advantages of blasting flame burner and direct injection flame burner, with a furnace heating speed, uniform temperature, energy saving, no blast, air ratio and a series of advantages. In our country, a large number of industrial furnaces still adopt the direct-fired direct-flame burner, such as the use of this kind of direct-fired flame burner, the flat flame burner can be used without additional blowers. Therefore, starting from the national conditions of our country, the development of the pilot flame burners to improve the level of industrial furnace technology and equipment, energy conservation has an important practical significance. Burner structure and principle Burner consists of ejector and cyclone, the structure See Figure 1.
