Abstrakt

Hybrid, wet/dry cooling systems enable significant water savings, albeit at higher cost, in comparison to wet cooling and provide improved plant efficiency and output at frequently lower cost in comparison to all-dry systems. This paper presents quantified tradeoffs among wet, dry and hybrid cooling systems for typical gas-fired, combined-cycle plants operating in a range of ambient conditions characteristic of the State of California in the US.
The results presented in this paper were obtained with an Excel spreadsheet-based computational tool used to specify, at an "engineering-level", design parameters for closed-cycle wet, direct dry and parallel wet/dry hybrid cooling systems. The tool was validated with thermal performance and water consumption data from operating plants equipped with wet, dry and hybrid cooling systems. Comparisons and tradeoffs among alternative cooling systems are described at five sites representing a wide range of environmental conditions.
