摘要
以1台50 MW燃煤发电机组为研究对象,对炉内燃烧状态进行了数值模拟,结果表明锅炉费斯顿管上部的温度比下部的温度约低100℃,中间位置处的温度比两边位置处的要高,这样将造成费斯顿管下部以及位于中间处的费斯顿管易结焦。分析原因主要是燃烧器布置不太合理,针对其存在的问题,提出了2种改造方案,并对这2种方案进行了比较。
Numerical simulation for boiler combustion status was conducted for a 50 MW coal-fired unit, and the result shows that the temperature in the upper area of the Feisdon tube is about 100℃ lower than that in the lower area of the tube, and the temperature in the middle of the tube is the highest, which is bound to cause clinkering in the middle of the tube. The root reason for the unbalanced temperature distribution is the unreasonable configuration of burners. The burners of the 50 MW boiler are analyzed, and two retrofit schemes are put forward and compared.
