White fume for gas turbine cooling tower

07/20/2011 12:44 AM

Hello everyone here.

I have a project to construct and to operate the combined cycle power plant and the project consists of the following equipment :

· Total capacity of combined cycle power plant is 1,560MW (780MW × 2Block) and Mitsubishi M501 GAC gas turbines arranged in 2 Blocks configuration (1Block : 260MW × 2GTs plus 260MW × 1ST)

· Small cooling towers will be incorporated to the main circulation water system

(MCWP quantity : Two 50% capacity / Block) used in the condensing and cooling for each ST.

I am afraid that there maybe the occurrence of white fume from cooling towers because it will be equipped in very cold, basin and inland area.

If you have the information to eliminate the white fume of cooling tower or if you know the similar cases like our power plant system, I hope you will give us a good help and detailed technical advice for our environment.

Thank you very much for your reading until now.

Don't use evaporative cooling towers, instead use radiators.

Thanks for your advice.

Do you mean that you recommend to use the dry cooling tower instead of wet cooling tower?

If the goal is to avoid creating a plume of evaporating water, exactly. A coolant to air heat exchanger if you will.

An air-cooled ("dry") tower will avoid mist/plume problems, but will be much larger in surface area, and thus more costly. Please see also the duplicate thread, which points to cooling tower plume abatement strategies.
