2003-6-1 · Keywords coal preparation, dry beneficiation, fluidized bed 1. Introduction In China, coal is the major source of energy and its leading role in energy consumption would not change in the next 50 years (Shi, 1995). More than 80% of coal is directly burned. As a result, the emission of 70% smoke/ dust and 85% SO 2 comes from coal combustion.
