摘要/Abstract

摘要： 基于对660 MW梯级供热机组耦合电锅炉运行特性分析，提出一种确定机组实时运行最佳经济背压的方法。试验表明控制机组主蒸汽流量和外界热负荷工况，参考最佳经济背压运行能有效增加机组的输出功率，可提高机组运行热经济性。机组梯级供热改造后，供热能力提升约440 GJ。在保证对外供热负荷不变时，梯级供热可降低发电机功率86 MW，提高机组调峰能力。在二档调峰工况对机组的经济性进行核算，发现相同热负荷下若采用电锅炉代替部分梯级供热量，电锅炉负荷每增加1 MW，机组折算标准煤耗升高约0.32 t/h。

Abstract: Based on the analysis of multi-stage heating 660MW unit combined with electric boiler, the method of calculating the most economical high back pressure for unit real-time operation was put forward. The experiment proved that operating under the most economical high back pressure could effectively increase the output power of the unit in controlling the main steam flow of the unit and the external heat load conditions and improve the thermal economy of unit. After the technical transformation, the heating capacity could be enhanced 440 GJ. When the external heating load was constant, multi-stage heating could decrease generator power by 86 MW and improved the peak load regulation capacity of the unit. The economy of the unit under the second gear peak shaving condition had been calculated. If the electric boiler replaced part of multi-stage heating under the same heat load, the unit conversion standard coal consumption increased by 0.32 t/h when the electric boiler load increased by 1 MW .

Key words: multi-stage heating, most economical high back pressure, electric boiler, economy, peak load regulation
