摘 要: | 通过对600 MW空冷供热机组不同供热抽汽量、排汽压力的试验,研究了供热抽汽量及排汽压力变化对机组主蒸汽压力的影响规律,并定量计算了不同试验工况下汽轮机热耗率的变化.提出了空冷机组全年高效定滑压运行模型,修正了机组原有的滑压运行控制逻辑.运行结果表明:按修正后定滑压运行曲线运行在450 MW、供热抽汽量300 t/h时,可降低供电煤耗1.1 g/(kW·h).

Abstract: | The variation of steam extraction volume and exhaust pressure with main steam pressure is studied through the tests on the 600-MW air-cooling heat supply units and the quantitative measurement on the changes of the heat consumption rate under the conditions of different extraction volumes and exhaust pressures is conducted. The year-around efficient fixed and sliding pressure operation model is put forward and the original unit sliding pressure operation logic is modified. The operation results show that a decrease of net coal consumption of 1.1 g/(kW, h) can be obtained when the sliding pressure curve is at the loads of 450 MW and the heating steam extraction is 300 t/h. |
