西固热电厂E42 0 - 13.7- 5 6 0KT型锅炉点火油枪雾化效果不佳 ,多次引起炉膛爆燃 ,必须对油枪及其系统进行改进。由于实际用的燃油粘度、压力、雾化蒸汽温度与俄方要求相差甚远 ,引起油枪雾化效果不良 ,严重影响锅炉的正常运行。更换成国产气泡雾化油枪后 ,由于该油枪利用特殊结构 ,使雾化蒸汽在燃油中形成大量的气泡 ,形成非常细小的液滴 ,与助燃空气混合充分后 ,形成均匀的液雾。使用结果表明 ,该油枪能保证锅炉正常点火及稳定燃烧。
Xigu Thermal Power Plant E42 0 - 13.7 - 5 6 0KT Boiler ignition oil gun atomization effect is poor, repeatedly causing the furnace deflagration, the gun must be improved and its systems. Due to the actual use of fuel viscosity, pressure, atomization steam temperature and Russian requirements far, causing poor effect of atomizer atomization, seriously affecting the normal operation of the boiler. After replacing the domestically produced bubble atomizing oil gun, the atomizing steam forms a large number of bubbles in the fuel oil due to the special structure of the oil gun to form a very small droplet. After being sufficiently mixed with the combustion air, a uniform liquid mist is formed. The results show that the oil gun can ensure the normal ignition and stable combustion of the boiler.
