Cooling Tower Target Nozzle
Friday, June 15, 2007
As promised, I'll share some informations about target nozzle which is among vital parts of a cooling tower. A target nozzle looks like the photo beside. That is a "Counterflow Nozzle Orifice" (sizes available from 1/2" - 1 1/2). A target nozzles function is to sprinkle the warm cooling water to increase its surface area (for heat transfer with air) before it goes down from the deck to the water basin. It is usually an injection molded polypropylene unit consisting of two parts—the main body with integral target diffuser and a snap-on insert or orifice cap. A cooling tower deck may have up to 200 or more target nozzles.
All this while I only know this type of target nozzle. After researching in the internet, I found there are various other types of target nozzles.
The first type (left) is a Counterflow Nozzle - 2" NPT Thread, (Orifice sizes 1/2" - 2"); the second (mid) is the a counter-flow down-spray nozzle; Square-Pattern, Full Coverage Type, 1-1/2" Standard Pipe Thread Connection; and the third (right) is a counter-flow up-spray Nozzle, fits 1-13/16" Diameter Hole in PVC pipe. There are more types of target nozzles at CoolingTowerNozzles.com.
