The paper reports controlled full-scale laboratory studies designed to determine if clay addition holds promise as a technique to control emissions from higher grade coals. (NOTE: Abnormally high rates of lung cancer are observed among persons in Xuan Wei County, China, who burn bituminous 'smoky' coal as compared with those who burn 'smokeless' coal, which is produced by mixing low grade coals with clay.) Statistically significant reductions in emissions of total particulate (70%), gravimetrically determined (nonvolatile) organics (70%), total chromatographable (semivolatile) organics (90%), and benzo(a)pyrene (65%) were observed (measured on a mass emitted/mass coal combusted basis) when clay binder material was added to a ground smoky coal. These reductions, however, did not fully account for the order of magnitude lower pollutant levels previously observed in homes burning smokeless (as compared to smoky) coal. Thus, the authors believe that the composition of the low rank coals used to produce smokeless coal also helps to control emissions.
