摘　　要：从外部性内部化及盈亏平衡理论出发,提出了基于固定成本、可变成本及减免排污费三者构成的燃煤电厂脱硝电价模型,并大规模调研了国内已安装脱硝设施机组(共103台、总装机容量4 300万kW)的脱硝设施投运情况,总结出影响机组NO x控制成本的主要因素,即装机容量、脱硝效率、建设时段及煤种,并计算了不同时段、不同装机容量的SCR与SNCR 2种主要脱硝工艺的成本,提出了采用SCR脱硝技术的新建机组执行1.0分/(kW·h)、现役机组执行1.2分/(kW·h)、采用SNCR技术的机组统一执行0.6分/(kW·h)的差异化的燃煤电厂脱硝电价方案。所得结论对于完善目前的脱硝电价政策具有重要参考意义。From the view point of externality internalization theory and breakeven analysis theory,the model of denitration electricity pricing is established consisting of fixed cost,variable cost and reduction of pollutant charge.Through extensive investigations on the operation of the denitration installations equipped in 103 existing thermal generating units totaling 43 000 MW,main factors contributing to the denitration cost are summarized,including the installed capacity,the denitrification rate,the construction period and the coal type.Moreover,the denitration cost of SCR and SNCR techniques for different time periods and different installed capacities is calculated.It is concluded that the price of 0.010 yuan/（kW ·h） and 0.012 yuan/（kW ·h） can be carried out for newly built power plants with SCR techniques and active power plants respectively,while the price of 0.006 yuan/（kW,h） should be adopted for all the power plants with the SNCR techniques.The conclusion may be of great importance to improve the policy for denitration electricity pricing.
