Pilot-Scale Boiler Study of Sulfur Hexafluoride and Emissions of CO, CO2, O2, and Unburned Hydrocarbons as Surrogates for Verification of Hazardous Waste Destruction Removal Efficiency.

摘要

The use of sulfur hexafluoride (SF6) as a tracer and emissions of CO, CO2, O2 and unburned hydrocarbons as surrogates for verification of hazardous waste destruction removal efficiency (DRE) is discussed. These measurements were made in a pilot-scale firetube boiler facility and in a natural gas fired steam plant boiler. The data indicates that toluene, methyl ethyl ketone and isopropanol are well-suited for destruction in a firetube boiler environment. Trichloroethylene and monochlorobenzene required auxillary fuel to maintain stable combustion. SF6 DRE was significantly lower than waste DREs for all runs. It also tracked waste DREs in most runs. Reduced waste and SF6 DREs were accompanied by lower emissions of CO2 and by increased emissions of O2 and total unburned hydrocarbons (TUHC). DREs tended to fall with increased CO concentration depicted by a few data points.
