摘 要: 阐述了燃煤电厂面临的电煤劣化和价格攀升的现实困难,各厂不得不通过混煤掺配掺烧来降低燃料成本和稳定锅炉煤质,由于配煤后的缺乏系统性经济分析评估,部分厂存在盲目配煤现象。通过建立配煤后经济性分析评估模型,科学量化指导电厂的燃煤掺配工作,将为提升火电厂的安全性和经济性起到积极的作用。

Abstract: In this papaer,it described what practical difficulties the coal-fired power plants are facing now,that is the Coal degradation and the rising coal prices. The plants have adopted with mixed coal blending to reduce fuel costs and maintain Stable combustion of coal boiler.Due to the lack of systematic economic analysis and Assessment, there is the phenomenon of blind blending. Through the establishment of blending economic analysis and the assessment model, it gave the scientific guidance to quantify coal-fired power plant blending.That will play a positive role in the enhance of safety and economics of thermal power plant.
Keywords: coal blending; power production cost; assessment
