In our studies, to enhance effective utilization of low-grade coals with high sulfur content and to control pollutant emissions from the sources in the region of Chongqing in China, a coal-biomass briquette technology and a new dry cleaning-coal technology by mean of static electricity were performed to separate the coal from pyrite, ash and various other minerals were developed in Chongqing. As the main results of the combustion experiments, coal-biomass briquette has the high desulfurization efficiency and lower ignition temperature and higher combustion efficiency than the local coal briquette. The locations, investment, production cost, market research, economical efficiency and pollutant emission control regarding the new manufactories in the future were investigated. It is revealed that the coal-biomass briquette technology and the static electricity dry cleaning-coal technology researched were simple, economical, and efficient and were considered to be very applicable for air pollution control of coal combustion in China.
