摘要

Chloromethane (CH_3Cl or methyl chloride) is a trace gas in the atmosphere that is a characteristic emission of vegetative biomass burning. Measurements of chloromethane emissions from laboratory-scale fires in forest fuels show that CH_3Cl emission factors vary considerably between flaming and smoldering combustion. Regression analysis indicates that CH_3Cl emission factors can be predicted from three fire and fuel parameters: combustion efficiency, rate of heat release, and fuel chloride content. The percentage of chlorine in the fine particle emissions from burning forest fuels also varies with combustion conditions. A combustion reaction mechanism is proposed to explain the observed variation in chlorinated emissions.
