摘　　要：为了适应严峻的煤炭市场行情,降低综合入炉煤价,提升企业经济效益,电厂三期烟煤锅炉采用了混合燃烧低挥发分煤种方案。在对混煤掺烧经济性评估研究中,提出了混煤掺烧边界理论的概念,进而可以直接判定当前煤价下混煤掺烧是否具有经济效益。Co-combustion of high and low volatile coal is adopted by the third phase bituminous coal boiler of the power plant in order to adapt to the severe coal market,reducing the comprehensive coal price and enhancing the economic benefits of enterprises.The concept of co-combustion boundary theory is proposed in the study of economic evaluation on co-combustion of high and low volatile coal,which can directly determine whether co-combustion of high and low volatile coal has economic benefits under the current coal price.

关 键 词：混煤掺烧 混煤掺烧边界理论 经济性评估 锅炉
