Abstract
ABSTRACT
In this project, air emission tests were conducted on seven boilers in the size range 0.4 to 15 × 106 Btu/hr while these boilers were firing waste oil. The main purpose of the project was to document the extent to which chemical contaminants in waste oil are destroyed during the combustion process. These data are of interest because one of the more common and wide-spread practices for disposing of waste oils is burning as a supplemental fuel.
Chemicals which were spiked into the waste oil before combustion included: chloroform, 1,1,1-trichloroethane, trichloroethylene, tetrachloroethylene, trichlorobenzene, 1-chloronaphthalene, 2,4,5-trichlorophenol, chlorotoluene. Destruction efficiencies ranged from 99.4 to 99.99 percent. Concentrations of these chlorinated hydrocarbons in the flue gas ranged from 40 to 400 μg/m3. The concentrations of lead and zinc in the flue gas ranged between 5,000 and 72,000 μg/m3 and 3,000 and 34,000 μg/m3, respectively. The average emission rate of HC1 from the seven boilers was 2.6 lb/hr.
