分析了某 2 2 0t/h锅炉尾部受热面的吸热情况 ,找出了影响锅炉热效率的原因 ,介绍了燃气冲击波清灰技术在螺旋鳍片管省煤器上的应用情况。通过合理的清灰措施 ,增加了受热面吸热 ,提高了锅炉热效率。
The endothermic situation of the heated surface of a 220t / h boiler was analyzed. The reason of the thermal efficiency of the boiler was found out. The application of gas blast ash cleaning technology on the spiral fin tube economizer was introduced. Through reasonable cleaning measures, the heating surface increases the heat absorption and improves the boiler thermal efficiency.
