Bete FGD Tech Manual - BETE Spray Nozzles - Spray Nozzle ...

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.

Upgrades to Wet FGD Absorber Spray Headers

Many wet FGD absorber modules were originally designed with spray patterns which do not maximize contact of the flue gas with the slurry spray. Older designs have gaps or openings in the spray pattern that allow flue gas to bypass the spray zones without contacting the slurry. Many of these gaps are on the outside of the absorber near the absorber walls. These gaps provide a direct path for ...

Dual Flow Tray Technology for Wet FGD Performance Upgrades

slurry sprays. Many Wet FGD’s have a side flue gas entry. The flue gas momentum pushes the gas to the far wall, where downstream resistance begins to redistribute the gas across the tower diameter. In open spray towers, the slurry sprays will redistribute the flue gas; however, this does not occur until the gas is well into the absorption ...
