针对常压管式加热炉热负荷≤２ ．５ ×１０ ９ Ｊ／ｈ 的需要，研究设计出了与之相匹配高效内混式多喷孔空气雾化油喷嘴，根据冷态试验结果，讨论了油枪喷嘴结构特点，火盆与雾化角的关系。该油枪喷嘴经中国人民解放军 ８７３５４ 部 队废油 更生 管式 加热炉 上实 际使用 表明， 其雾化 粒度（ 索太 尔平 均直径 Ｓ Ｍ Ｐ≤２０ μｍ ） ，不易堵塞，结 焦， 强化了燃烧，该油枪喷嘴性 能良好，操作灵活，安装维护方 便， 火焰刚性好、集中明亮。喷嘴雾化角和孔数及孔径的选择完全适应加热 炉炉膛几何尺寸，并能充分满 足热负荷需要，燃烧火盆的出口锥角与喷嘴雾化角之间的间距选择恰当，解决 了火盆出口锥角过大或过 小造成喷嘴喷出的气雾离焰、脱火及火盆结焦和烧损现象
For atmospheric pressure tube furnace heat load ≤ 2. 5 × 10 9 J / h, we designed and matched the highly effective mixed multi-orifice air atomizing oil nozzle. According to the cold test results, the structure characteristics of the nozzle oil nozzle were discussed. Relationship. The actual use of the nozzle of the oil gun by the Chinese People’s Liberation Army 87354 unit waste oil rejuvenation tube furnace shows that the atomization particle size (Sothiger average diameter S M P ≤ 20 μm), not easy to plug, coking, enhanced combustion, The oil gun nozzle performance is good, flexible operation, easy installation and maintenance, flame rigidity, focus on bright. Nozzle atomization angle and the number of holes and the diameter of the hole completely adapt to the furnace geometry, and can fully meet the needs of thermal load, the combustion cone angle of the nozzle and the spray nozzle angle between the appropriate choice to solve the brazier outlet cone Angle is too large or too small to cause the spray nozzle spray away from the flame, fire and brazier coking and burning phenomenon
