摘　　要：在330 MW机组整套启动调试期间,锅炉在满负荷下需要投入多只油枪助燃运行。调试单位同锅炉厂技术人员人员进行了大量的燃烧调整工作。通过调整,虽然减少了油枪投用的数量,但无法完全断油。经试验和调研分析,调试人员认为锅炉热负荷设计不足是导致无法断油的根本原因。通过增加炉膛卫燃带,提高锅炉热负荷,锅炉改造成功,最终实现了断油稳定运行。During the commissioning period of 330MW uni4 it is necessary for boiler with full load to use several oil guns to support combustion. Although the adjustment is done to reduce the number of the oil guns in operation, all oil guns still cannot be cut off. The test analysis indicates that insufficient thermal load is the basic reason for the operation with fuel oil supporting. After adding refractory belt to increase the thermal load, the boiler can operate stably without fuel oil supporting.
