小油枪点火技术在超临界直流锅炉吹管中的应用

Application of Low-oil-consumption Ignition Technology in Steam-line Blowing of Supercritical Pressure Once-through Boiler

扼要介绍华能沁北电厂3号600 MW机组锅炉应用小油枪点火吹管的情况,其节油效果明显,在对3号炉吹管阶段调试及运行经验进行总结的基础上,给出了小油枪运行方式下相关参数的控制及操作注意事项。

The paper briefs the application status of low-oil-consttmption ignition technology in the steam-line blowing of No.3 600 MW supercritical pressure once-through boiler in Huaneng Qinbei Power Plant, the oil-saving benefit is evident. Based upon the summing-up of debugging and operation experiences in the steam-line blowing period of No.3 boiler, the paper gives the control of relevant parameters and manipulation matters needing attention in the iow-oil-consurnption ignition operation.
