摘　　要：华东电网节假日期间的负荷特性和日电量曲线变化幅度较大.为适应电量变化,大型火电机组深度调峰势在必行.锅炉燃料特性和最低稳燃特性是燃煤机组深度调峰的影响因素.根据华东电网调峰的要求,句容电厂对1#机组进行了深度调峰研究并开展了深度调峰实践.结果表明,1 000 MW对冲燃烧方式锅炉深度调峰期间最低稳燃负荷可以达到250 MW,同时可以保证脱硝、脱硫、除尘设备的正常运行.The range of load characteristics and daily power curve of the East China Power Grid changes significantly during the holiday. In order to adapt to changes in electricity consumption,the large capacity units to participate in peak regulation is imperative. The boiler fuel characteristics and the minimum stable combustion characteristics of coal-fired unit are factors in the peak peaking. In compliance with the East China Power Grid Dispatching Center requirements,the Unit 1 in Jurong Power Plant carries out the study and practice of the depth of peaking. The results showthat the1 000 M W opposing the firing boiler under the minimum stable-combustion load can reach 250 M W. At the same time,the denitration,desulphurization and dedusting system work properly.
