Staley, L. INTERIM REPORT ON PIC (PRODUCTS OF INCOMPLETE COMBUSTION) MINIMIZATION IN A RESEARCH COMBUSTOR. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-85/082 (NTIS PB85233336), 1982.
Description:
A series of five organic compounds (1,1,2,2-tetrachloroethane, trichloroethylene, Freon-113, carbon tetrachloride and chlorobenzene) were burned in heptane in a 100,000 Btu/hour water-jacketed research combustor in order to determine what, if any, PICs (Products of Incomplete Combustion) formed under conditions of extreme flame quenching. For each test, excess air levels were varied from 120% of theoretical air to 240% of theoretical air which, for the combustor used, represented the limits of flame stability. Results show that PICs do not always occur predictably, but are very much influenced by the POHC (Principal Organic Hazardous Constituent) being burned. Where they do occur though, the emission levels of PICs increase with increasing levels of excess air, over the range of air levels investigated. The report covers the period of January-March 1985, and the work was completed as of March 31, 1985.
