Summary:Abatement systems are used to remove harmful pollutants resulting from manufacturing processes. Prior art abatement systems can dangerously back-flash due to, for example, changes in gas velocity and if the inlets become constricted due to clogs. To prevent back-flash a sprayer is introduced to an inlet of the abatement system. The sprayer sprays a volume of a cooling liquid, such as water, into the inlet. In the event of a back-flash, the liquid can extinguish the flame, preventing further damage to the abatement system. The sprayed liquid can provide further benefits, such as cooling the incoming, mitigating effects of reactions within the cooling gases, and flushing away solid particles that would otherwise clog the inlet. These further benefits can allow the abatement system to safely handle additional gases and larger volumes of incoming gas.
