燃气-蒸汽联合电厂冷却塔选型配置研究

Research on Choice of Cooling Tower in Combined-Cycle Power Plant

冷却塔塔型的合理选择是电厂安全可靠、经济高效运行的重要保证。以某1×470 MW级燃气—蒸汽联合电厂为例,首先针对带机械通风冷却塔的二次循环供水系统进行优化分析计算,然后采用“冷效相同”原则,对本工程循环水系统采用不同塔型的方案进行技术经济比较。

Reasonable selection of cooling tower type is an important guarantee for safe,reliable,economical and efficient operation of power plant.Taking 1×470 MW combined-cycle power plant as an example,the first for secondary circulating water system with mechanically vntilated cooling tower is optimized analysis and calculation,and then the principle of"same cooling effect"is adopted,this project scheme of circulating water system with different tower type technical and economic comparison,the selection of gas turbine power plant cooling towers is of great significance.
