摘　　要：运用热平衡的计算方法,对对流受热面进行热平衡和传热计算;使用锅炉实际连续运行数据做模拟离线监测,监测结果分析验证了模型的准确性和可靠性。探讨了负荷对监测结果的影响,从稳定负荷时间段和变化负荷时间段,分析负荷与清洁因子的关系,从而优化吹灰。The paper used calculation method of heating balance theory which applied to the calculation of the convective surfaces. Then make analogue off-line monitoring based on the practical continuous running data of the boiler. The monitoring result analysed and proved the reliability and accuration of the modle. At last, this paper discussed the affect of load to monitoring result from stabilization load time and variation load time. In order to guide sootblowing optimization, this paper pointed out and analysed the connection of the load and the cleanliness factor.
