| Abstract |
The report gives results of a study of the formation and growth of sulfate particles. Existing theoretical models on acid particle formation and growth were reviewed and evaluated. The formation and growth of sulfate particles during slow cooling, rapid cooling, and dilution cooling of flue gas were experimentally determined and compared with theories. The experimental results show that the temperature at which the self-nucleation of sulfuric acid occurs is lower than the acid dew point temperature. Thus, if the flue gas is slowly cooled to between dew point and nucleation temperatures, it is possible to force the sulfuric acid to condense out on surfaces, rather than form fine particles. The theories, experimental methods, and results are described. |
