摘要
介绍了微油点火技术在某台2 093 t/h燃用贫煤锅炉上的应用情况,并进行了微油点火燃烧稳定性试验研究,分析了一次风速、煤粉浓度和气膜冷却风比例对炉内燃烧稳定性的影响。研究得出,微油点火系统简单可靠、投资少,平均每投入1 h约可节约燃油6.67 t,节能效果显著。为其他锅炉节能燃烧及微油燃烧器改造提供了参考。
Application of tiny-oil ignition technology on a 2 093 t/h meager-coal fired boiler is presented and research on stability combustion based tiny-oil ignition is completed. The influence of primary air velocity, pulverized coal concerration and film cooling air proportion on combustion stability are analyzed. Experimental research shows that tiny-oil ignition system is simple and reliable, and needs less investment, 6.67 t oil is saved when the system is used per hour, and the effect of energy conservation is obvious, so it provides a wonderful reference for energy conservation and technical improvement of tiny-oil burners on boilers.
