介绍的是鞍钢大型轧钢厂对3号加热炉所实施的两次油气两用技术改造,一次是随着生产的发展和民用煤气的增加,冬季煤气出现很大缺口,要求季节性烧油的情况下进行的,一次是在供应鞍钢的重油粘度大大增加、使燃油无法正常的情况下进行的。改造后的生产表明,高压内混油枪的燃烧效果,优于高压外混式油枪;燃用高粘度重油困难较大,要在合适燃烧条件下,才能达到预期的燃烧效果,可收到加热炉节能16％,增产7.4％～11％的效果。
Introduced is Anshan Iron and Steel rolling mill on the 3rd furnace implementation of the two oil and gas technology transformation, once with the development of production and civil gas increases, winter gas has a big gap, requiring seasonal oil situation Under, once in the supply of heavy oil viscosity Angang increase greatly, so that the fuel can not be carried out under normal circumstances. After the transformation of the production shows that the high pressure within the mixing gun combustion effect, superior to the high pressure outside mixed gun; burning high viscosity heavy oil difficult, in the appropriate combustion conditions, to achieve the desired combustion effect can be received 16% energy saving furnace, an increase of 7.4% ~ 11% of the results.
