I am looking for Particular solutions for increase the cooling capacity of an existing natural draft dry cooling tower in a 200 MW steam power plant, such as adding the height of radiators, installing electrical fans inside the tower and etc.
The cooling capacity of such a system should increase with any of the following. Some can only effectively be done at the design stage and others are retrofittable.
1. Increase in diameter
2. Increase in height (will increase draft and therefore capacity)
3. Any measure that increases pressure or flow rate (fans). though adding fans will make the system no longer natural.
4. Any measure that increases average internal temperature (radiators)
5. Any measure that decreases average molecular weight (vaporizing moisture), though adding moisture will also change temperature and will make the system no longer dry by most definitions.
Dear Mr. Baxter, thank you for your suggestions.
I knew the mentioned methods and there are some other methods, but I am looking for the best way and want to know about the others experiences.
Do you have any practical work experience in this field?
Increasing the performance of a natural draft tower is much more difficult than a mechanical draft one. For example, more closely packed fill can increase the pressure drop and decrease the airflow, yielding little or no benefit. It can also work better for a while and then plug up. Experience has proven that the best approach is attention to detail (i.e., fix every little gap and dribbling nozzle). Many people have devoted their careers to this task. Most of these are active in the CTI. John Cooper is a very clever guy and old friend. He has posted lots of pictures online that will give you ideas of what to look for.
