|Emission characteristics from the combustion of boiler briquette coal and raw coal were analyzed using a self-designed dilution sampling system that was manufactured to sample the particulate pollutants such as PM2.5, PM10, and metal elements in flue gas from stationary source . The results showed that the fine particle emission ratio of briquette coal was higher than that of raw coal, and that the mass of PM2.5from the inlet and outlet of the dust collector had increase of 715% and 708%, respectively, for briquette coal than raw coal. The mass fractions of As and Pb at different particle size ranges were all higher for briquette coal. At the same time, due to the increase of inhalable particulate matter during the combustion of briquette coal, emission ratio of metals that were contained in or attached to the dust was also increased.
