Accurate Calculation and Application of Denitration Flue Gas Heating Process Based on CoolProp
Under the requirements of high-quality and sustainable development in the steel industry,ultra-low emissions and energy conserva-tion and carbon reduction have gradually become industry consensus.The SCR denitrification process has been widely used in ultra-low emis-sion transformation of steel enterprises due to its high denitrification efficiency.In this paper,thermodynamic analysis is conducted on the com-mon flue gas heating process in SCR denitrification process.Compared with the traditional theoretical method,the physical property calculation model based on CoolProp is introduced,the influencing factors of gas temperature are added,and the Python software is compiled,finally we realizes the accurate calculation of the whole heating process.The software presets the common flue gas and gas composition data,and the physical parameters can directly obtained without using the manual,which can significantly improve the work efficiency in the engineering ap-plication.By analyzing the calculation results of typical cases,the quantitative relationship between gas consumption and flue gas temperature rise range(Δt),flue gas initial temperature(t1),air excess coefficient(α)and gas type are obtained.So as to obtain better operation pa-rameters.It can provide reference for relevant design or operation.
