对某燃煤电厂电除尘器和文丘里湿式除尘器收集的飞灰中的有机物进行了分析。固体废物提取物中的有机成分包括大量的脂肪族和芳香族化合物。在脂肪族馏分中发现了一系列正构C/sub 15/-C/sub 30/链烷烃。芳香族化合物为1、2、3、4环芳香族化合物。含4个以上环的多环芳烃的回收率很低。从WS和ESP的飞灰提取物中的有机成分的比较表明，ESP提取物含有更多的化合物，更大的数量。回收的有机化合物的种类和数量预计不会对环境造成任何危害。
Organic compounds recovered from fly ash collected by an electrostatic precipitator (ESP) and a venturi wet scrubber (WS) at a coal-fired power station were analysed. Organic constituents in extracts of solid waste included large numbers of aliphatic and aromatic compounds. A series of normal C/sub 15/-C/sub 30/ paraffins was found in the aliphatic fractions. The aromatic compounds were of 1,2,3 and 4 rings. Polynuclear aromatic hydrocarbons containing more than 4 rings were shown to be poorly recovered. Comparison of organic constituents in extracts of fly ash from the WS and the ESP showed that ESP extracts contained more compounds in greater quantities. The types and quantities of organic compounds recovered are not expected to present any environmental hazard.
