Enclosed Oxidizing Flares convert VOCs into CO2 and H2O by way of direct combustion. Normally an enclosed oxidizing flare is used when the waste gas is rich enough in organic content to be its own fuel source. If the process gas stream does not contain an adequate level of combustible VOCs then additional fuel must be supplied for effective operation. The removal efficiency for each control device is a function of the specific design of the unit and how well its capability matches the intended application.
