超(超)临界空冷机组冷端优化技术探讨
摘要
汽轮机冷端系统是火电厂重要辅助系统
需从节能和节水方面对其进行优化。通过对某电厂超临界600 MW空冷机组冷端优化的实例计算
表明超临界600 MW空冷机组最佳运行工况在净发电量最大的4号工况点附近。据此
提出了超超临界1 000 MW空冷机组冷端优化的方案。
Abstract
The cold end system of steam turbine is an important auxiliary system in thermal power plants
it is necessary to optimize the said system in aspects of energy-saving and water-saving.Through practical example of calculation for cold end optimization of a supercritical 600 MW air-cooled unit in one power plant
it shows that the optimal operating condition of said 600 MW air-cooled unit is located nearby the operating condition point no.4 with maximum net electricity generation
and based on this
a scheme of cold end optimization for ultra-supercritical 1 000 MW air-cooled unit has been put forward.
