Bete FGD Tech Manual - BETE Spray Nozzles - Spray

2018-12-31  The function of a spray nozzle in the absorber of a wet limestone FGD system is to convert bulk slurry into droplets and to bring these droplets into intimate contact with the flue gas in the absorber tower. There are few decisions more critical to the operation of the FGD absorber tower than the selection of the spray nozzles.
