Abstract: The particulate matter size distribution and chemical element of particles both emitted and collected by precipitators from different processes, including coal broken, ingredient, sintering machine head, sintering machine tail and product screening of sintering process,were measured in site of an iron and steel enterprise. Based on the test results, the comprehensive evaluation index in each dust emission point of the sintering process were established. The weight of each evaluation index was obtained from experts. Then, each dust emission point was evaluated by the method of fuzzy comprehensive evaluation. The results showed that the sintering machine head is the most important dust emission point with the most emission quantity and the highest mass fraction of PM2.5, PM10 and heavy metals.

Key words: sintering process, PM2.5, PM10, heavy metal, evaluation of dust emission
