1000 MW火电机组冷端优化分析

Optimization Analysis of Cold End of 1000 MW Thermal Power Unit

为了选取安徽某电厂二期扩建2×1 000 MW机组最优的冷端优化结果,根据不同冷却倍率、凝汽器面积、冷却塔面积、设计背压,并结合考虑最小年费用法,最终选用了设计背压为5.2 k Pa,冷却塔淋水面积为12 000 m^2,凝汽器面积为52 000 m^2的最优化方案.

In order to select the optimal cold end optimization results of the second phase of expansion 2 × 1 000 MW unit of a power plant in Anhui Province, according to the different cooling rate, condensing collector area, area of cooling tower, design pressure, combined with considering the minimum annual usage, this project selects design pressure for 5.2 kPa, cooling tower water spraying area 12 000 m2 ,and condenser area is 52 000 m2 of the optimized plan.
