Making a systemic study to physical and chemical properties with six kinds of representative coal and four kinds of blended coal, which is common used in northeast of china, proposes the characteristics of ten kinds of coal, which includes moisture, ash, volatile matter, carbon, hydrogen, nitrogen, sulfur, HIG, true relative density of ash, composition of ash, etc. And selected ten representative kinds of coals, according to a grey synthetic decision-making system with use of an analytic hierarchy process is introduced to evaluate the performance of coals form five main aspects, which were industry analysis, elemental analysis, calorific value, physical properties of coal, chemical composition and temperature of coal ash. The result shows that it can provide to choose a suitable and economical coal type according for operating conditions of power plant.
