Cooling towers on power stations - why?

Stephen Biddle
Hi All


I was working on a power station in Oman last month and it was gas fired with condensing steam turbines - no evaporation.  This week I'm working on a coal fired one in Poland, which has cooling towers and evaporation.  Is it something to do with the gas or just that they have no water in Oman?


Thanks

    There are proposals for extracting power from the small temperature difference between surface and deep ocean water in places like Hawaii, using ammonia as a working fluid. Surely a coal-fired power station has much higher residual heat than that. So why not put an ammonia-cycle turbine or Sterling engine on the back end instead of blowing all that heat away as steam? You could do the same with any significant waste heat, be it from a steam turbine or a diesel.
