烟气同时脱硫脱硝化学反应的可能性分析

根据烟气气体组分情况，将可能发生的化学反应方程式进行筛选，确定独立反应个数。通过热力学计算得到了标准状态下热力学函数值，进而求得了不同温度下的热力学性质。通过标准生成自由焓、标准吉布斯自由能变、标准熵变的计算，分析了烟气同时脱硫、脱硝中发生化学反应的可能性，为烟气同时脱硫、脱硝动力学理论的研究打下了基础。

Feasibility analysis on chemical reaction in simultaneous desulfurization and denitrification of flue gas

According to the components of flue gas under the circumstances, the possible chemical reaction had been selected. The number of independent reaction were determined. The standard state thermodynamic function values and the thermodynamic properties at different temperatures were obtained by the thermodynamic cal- culation. The feasible chemical reactions on simultaneous desulfurization and denitrification were researched by the standard formation enthalpy of Freedom,the standard Gibbs free energy change and the standard entropy change. The result provided support for the further research on simultaneous desulfurization and denitrification of flue gas.
