针对目前电力市场需求不旺，电厂调峰任务重的实际情况，综合分析国产 ６７０ ｔ／ｈ 无烟煤锅炉不能适应电网调峰需要所存在的问题，提出增强锅炉调峰能力，保证低负荷工况稳燃与节油的配套改造方案；阐述百叶窗式水平浓淡煤粉燃烧器的稳燃机理及燃烧器配套改造前后的运行情况，考核试验和节能效果。
Aiming at the current weak demand in the electricity market and the peak load of power plants, this paper analyzes the problems that the domestic 670 t / h anthracite coal boilers can not meet the need of power grid peak regulation, and proposes to enhance the boiler peak regulation capacity and ensure stable operation under low load conditions Combustion and fuel economy of the transformation program; described shutter-type horizontal and lean pulverized coal burner combustion mechanism and burner supporting the transformation before and after the operation of the assessment test and energy-saving effect.
