摘要
某电厂660 MW超超临界机组引风机采用回热式小汽轮机驱动,同时回收小机排汽热量,提高了机组热力循环综合效率,通过计算,厂用电率加权平均值降低约1.48%,供电煤耗的加权平均值可下降2.02 g/kWh,节能效果显著。
The induced draft fan of 660 MW ultra supercritical unit in a power plant is driven by regenerative small steam turbine.At the same time,the exhaust heat of small turbine is recovered,and the comprehensive efficiency of thermal cycle of the unit is improved.Through calculation,the weighted average value of auxiliary power consumption rate is reduced by about 1.48%,and the weighted average value of coal consumption for power supply can be reduced by 2.02 g/kWh,and the energy saving effect is remarkable.
