ABSTRACT:
A method for monitoring and/or controlling performance of a selective catalytic reduction (SCR) emission control system includes injecting a quantity of a pollution neutralizing gas into a combustion gas stream containing a pollutant gas. The method also includes passing the stream over a catalyst bed to facilitate a reaction of the pollution neutralizing gas with the pollutant gas to produce an effluent and measuring a ratio of the pollution neutralizing gas to the pollutant gas in the effluent.
