Sulfur Hexaflouride as a Tracer for the Verification of Waste Destruction Levels in an Incineration Process
Abstract
The use of sulfur hexafluoride (SF6) as a tracer for the verification of hazardous waste destruction levels in an incineration process is discussed. This study determined the relationships between fuel flow, air flow, temperature, and mixing, and the destruction removal efficiency (DRE) of SF6 in a laboratory natural gas burner. The motivation for the study was the need to establish fundamental relationships which could be used in later studies concerned with using SF6 as a tracer in combustion processes. SF6 was mixed with natural gas and burned in a turbulent diffusion flame, typical of industrial boiler flames. The SF6 DRE was determined for various air and fuel flow rates, and for two different burner mixing conditions. Laboratory samples of three compounds typically found in Air Force hazardous wastes were also vaporized samples of three compounds typically found in Air Force hazardous wastes were also vaporized and burned. The compounds were toluene, benzene, and trichloroethylene. The DREs of these compounds were greater than the DRE of SF6 when burned under the same conditions. An empirical relationship was developed, relating the DRE of SF6 to a characteristic time, based on fuel flow and adiabatic flame temperature, and an empirical rate constant, based on the adiabatic flame temperature.
