Selective catalytic reduction (SCR) modeling using parallel way of identification

This work introduces a parallel way of identifying an SCR model in coal-fired power plant. In order to avoid large disturbance in excitation, we perform two iterations of the identification test. Asymptotic method (ASYM) is used in two tests and model quality improves gradually. Based on the analysis of costs and model quality with industrial data, we verified the effectiveness of the method.
