摘　　要：某330MW锅炉燃烧器区域水冷壁左墙、前墙发生严重结焦情况,煤质适应性差,严重影响锅炉安全经济运行。为探讨锅炉热态动力场纠偏技术依据及效果,开展冷态动力场纠偏诊断试验,验证了通过针对性调整二次风门可在一定程度上调节热态动力场强风环位置。根据冷态动力场纠偏试验结果,进行了热态动力场优化燃烧调整,使得锅炉左墙、前墙结焦情况明显缓解。This paper focuses on the serious coking observed on left and front water walls in burner area encountered by a 330 MW boiler in an thermal plant which resulted in poor adaptability to coal quality and seriously affected safe and economic operation of the boiler.In order to explore technical basis and utility of bias correction of boiler thermal dynamics,cold status bias correction experiment was carried out,which verified that adjusting secondary air valve can control to a certain extent the position of strong wind ring under thermal dynamic field.According to that result,practical application of the bias control scheme to thermal dynamics of ther burning boiler was conducted,and was proved to alleviate obviously coking on the left and the front water walls.
