Emissions of organic hazardous air pollutants during Chiense coal combustion

摘要

This paper provides a general investigation of the emissions of organic hazardous air pollutants (HAPs) during the combustion of several typical Chinese coals. First, the distribution of four types of HAP, i.e., aliphatics, cyclic hydrocarbons, monoaromatic compounds and PAHs, in the CH_2Cl_2 extracts of six Chinese coals were studied and the influences of the extractive times and coal varieties wee also evaluated. Second, the partitioning of these HAPs in the flue gas during coal combustion in a small-scale reactor were investi- gated, depending on over temperatures (500 deg. C, 600 deg. C, 700 deg. C, 800 deg. C, 900 deg. C) and coal varieties.
