Abstract
One embodiment of the present disclosure describes an industrial system, which includes a control system with a predictive emissions monitoring system that facilitates determining a chemical level output from a selective catalytic reduction unit that reduces the chemical level in gaseous emissions produced by a combustion source using a selective catalytic reduction model. The control system tunes the selective catalytic reduction model by determining tuning parameters based at least in part on vendor information and tuning data determined via a tuning sequence. The tuning sequence includes operating the combustion source at a plurality of load levels, injecting a reactant into received gaseous emissions at each of the plurality of load levels in accordance with an injection rate provided in the vendor information; and determining an input chemical level to and an output chemical level from the selective catalytic reduction unit at each of the plurality of load levels.
