摘要： The dominant status of coal on the energy production and consumption structure of China will not be changed in the middle period of this century. To realize highly efficient utilization of coal, low pollution and low cost are great and impendent tasks. These difficult problems can be almost resolved through establishing large-scale pithead power stations using two-stage highly efficient dry coal-cleaning system before coal burning, which is a highly efficient, clean and economical strategy considering the current energy and environmental status of China. All these will be discussed in detail in this paper.
