摘要: 针对国华宁海发电厂600 MW亚临界汽包锅炉进行了优化燃烧调整试验,采取了不同负荷下变配风方式、降低一次风参数以及合适的氧量控制等措施,在各负荷点下,不仅降低了三大风机的耗电量和NOx排放质量浓度,提高了锅炉整体经济性,同时也增加了风机的裕量。根据试验结果制订了锅炉的优化运行指导卡,可为电站锅炉的经济运行提供参考

Abstract: Aiming at the 600MW subcritical drum boiler of Guohua Ninghai Power Plant, an experiment of combustion optimization control was carried out. Under different load, some measures, such as to change the air distribution mode, to reduce the parameters of the primary air and to control the oxygen properly, were adopted. Under various load points, the power consumption of the three fans (the induced draft fan, the forced draft fan and the primary air fan) was reduced. The mass concentration of the NOx emission was reduced. The overall economic efficiency of the boiler was improved. Simultaneously, the capacity margin of the fans was increased. According to the experimental results, the boiler optimal operation instruction sheets were formulated, which can be used as reference for economic operation of boiler of power plant.
