摘要
针对220 t/h高压自然循环煤粉锅炉炉膛出口烟温高和热偏差大现象进行原因分析,通过调整一次风速和大、小二次风门,保证锅炉稳定运行。
The reasons of high flue gas temperature and large thermal deviation at the outlet of furnace in 220 t/h high pressure natural circulation pulverized coal boiler was analyzed. The regulation of primary air velocity and secondary damper （the bigger one and the smaller one） ensured the steady operation of the boiler.
