Abstract


Due to the current market supply of coal for power generation , power plants generally face coal changes , the actual burning coal for larger changes than the design coal , a direct result of the decline in efficiency of the boiler , the decline in overall plant economics . While the power generation business to enhance the economy , improve enterprise efficiency , and actively seek more appropriate source of new coal through positive and the technological transformation to adapt to the quality variation . This article was introduced first on our country and on the international steam coal blending history and Research . A brief analysis of the more popular power the blending calculation method , according to the characteristics of the actual application requirements , calculated on the basis of the weighted average method focuses on the constraints , the mathematical model . According to the mixed coal coal volatile linear heat coalification parameters can be added , the use of steam coal blending principle of weighted average method , by the ignition characteristics of coal-fired slagging characteristics , milling system drying power change and other aspects of the next garden power plant boiler burning, Yuxian coal blended with the feasibility analysis , the technological transformation of the recommendations put forward to ensure crew safety , economic operation prerequisite .
