Abstract:

Methods of assessing the destruction and removal efficiency (DRE) of a thermal combustion device having a gaseous effluent according to the formula DRE=100. times. (W. sub. in -W. sub. out)/W. sub. in where: W. sub. in =mass feed rate of an organic compound into the device, and W. sub. out =the mass emission rate of the organic compound in the gaseous effluent. An apparatus for determining the destruction and removal efficiency of a thermal combustion device is also described. The methods and apparatus are capable of assessing the DRE in real time and are particularly useful in thermal combustion devices regulated by the U. S. Environmental Protection Agency that combust or burn hazardous materials containing organics.
