摘　　要：针对广东粤电集团云河发电有限公司5号、6号锅炉在改烧非设计煤种——低灰分印尼褐煤过程中,出现床温偏高、炉内温度分布不均、循环灰量不足,严重影响锅炉安全运行等问题,从调节入炉煤粒径、高压流化风风量、总风量、一次和二次风配比、上下二次风配比、床压等参数方面,开展了不同负荷工况的各种燃烧优化试验,有效地解决了锅炉由于改烧低灰分印尼褐煤所导致的一系列问题,使改烧低灰分印尼褐煤具有较可观的经济效益和推广应用前景。In allusion to problems such as high bed temperature, uneven distribution of furnace temperature, insufficient cir- culating ash quantity of No. 5 and No. 6 boiler of Guangdong Yudean Group Cloud River Power Company Ltd. in the process of its changing to burn non-design coal Indonesia lignite, which seriously affect safe operation of the boiler, this research de- velops various combustion optimization experiments under different load working conditions in terms of adjusting grain diam- eter of furnace coal, air quantity of high pressure fluidizing air, total air quantity, matching of primary and secondary air, matching of up and down secondary air, bed pressure, and so on, which effectively solve a series of problems caused by the boiler changing to burn low ash content Indonesia lignite and make it have considerable economic benefit and broad prospect in application.
