BETE provides nozzles for every part of flue gas desulfurization (FGD) systems, including FGD emergency quenching nozzles. In a FGD system, the flue gas has an optimal temperature to ensure the proper functioning of other components of the system. If the flue gas exceeds this temperature, emergency quenching nozzles spray water into the stream to cause evaporative cooling, avoiding damage to downstream equipment.

FGD emergency quenching nozzles are fitted to produce the smallest droplet sizes possible in order to maximize cooling potential. BETE engineers can help find the best nozzle for this purpose for your FGD system.

Common Designs and Specifications:

Common Nozzle Types: spiral, Air Atomizing
