Cooling system dynamics and control.
The cooling water system is a lossy loop. Water starts in the BASIN at the bottom of the cooling tower. It flows into a smaller COLD-WELL into which additives go and from which water is PUMPed to go through HEAT EXCHANGERS. There will probably be many heat-exchangers in parallel or series paths of various lengths. Return water goes past a BLOW-DOWN valve which allows water to be taken out of system. Then on to top of tower to meet FANned rising AIR and loose heat by evaporation in falling down into the BASIN.
The use of evaporative cooling, as in a tower, causes build up of salt concentrations in the cooling water. Drawing off some of this briny water and making up the losses controls how salty it becomes. Such blow down, of course, also removes some of the chemical additives put in to inhibit corrosion and fouling.

|Invitation. McCann can help if you have a
design or operational problem that needs some technical support that is outside your
team's experience, some quantitative assessment of what is really the cause of the
difficulties, some design alternatives or just a fresh look by an intelligent
If you have a problem with the behaviour of a market sector, plant, process or item of equipment and would like to get a quantitative handle on it to improve yield or optimise performance, then contact me. I'm always ready to give a little time to discuss a new puzzle, in confidence, of course. We'll only worry about fees when there is some defined work. I can be flexible about how I work with you.
