摘　　要：无烟煤宜采用W型火焰燃烧方式,但由于无烟煤挥发分低,无法采用等离子点火技术,为在启动和低负荷阶段节油,600MW超临界W型火焰炉采用双强少油点火技术,因此需对原燃烧系统进行改造,并对控制逻辑进行修改。采用双强少油点火技术燃烧稳定,满足机组启动稳燃要求,节约大量燃油,并可在点火初期投入电除尘器,福溪电厂的改造经验可为同类型机组的改造及运行提供参考。Anthracite should adopt the W type flame combustion mode, but the anthracite volatile is too low, cannot be used for plasma ignition technology, in order to save oil during the startup and low load stage, 600 MW supercritical W type flame boiler adopts double strong little-oil ignition technology, therefore need to reform the combustion system and the control logic. Double strong little-oil ignition technology meet the stable firing, meet unit start stable-combustion requirement, saves a lot of fuel oil, ESP can be put into operation during ignition early. The experience of Fu Xi power plant can be referenced by other same units.
