Abstract
Air pollution such as PM2.5 and PM10 has become a serious problem for many cities in China. One of the key factors for the causation of air pollution is the exhausts of coal combustion. The combustion efficiency and emission will be affected by different type of coal. Thus, four raw coals include Gaoping anthracite coal, Tangshan bituminous coal, Liupanshui lean coal, and Indonesia lignite coal are selected for the combustion process simulation and analysis based on Aspen Plus. The results show that the combustion heat of anthracite coal reached the highest level based on same combustion condition. According to the emission results of the selected coal, the combustion temperature just has a little impact on the emission of SOX, while the emission of NOX will increase when the combustion temperature increase. The study may provide a constructive strategy for the selection and utilization of different type of coal for relevant industry.
