Abstract

In the present study, the effect of the flow pattern of the inlet flue gas were investigated on the denutrification performance through the numerical simulation. As the examples of the off-design conditions, the skewed and double parabolic flow were chosen to compare the uniform flow used as the design condition. The SCR type of DeNOx facilities of the large-scaled coal-fired power plant currently in operation were adopted as the application model. In order to to deduce three performance variables, the steady two-dimensional turbulent flow were solved using the thermal-flow software named as ANSYS-Fluent. Comparing the off-design conditions to the design condition, the computational results showed that the predicted performances differed by 15.6% for the flow uniformity, 127% for NH₃/NO molar ratio of the mixed gas and 10.2% for the pressure loss of the whole process.
