Zusammenfassung:	A method of operating an emission abatement system having a selective catalytic reduction (SCR) catalyst includes supplying fuel to a fuel-fired burner positioned upstream of the SCR catalyst to heat exhaust gas being advanced to the SCR catalyst. The method further includes determining a flow rate of fuel being supplied to the burner, and predicting the amount of fuel to be further supplied to the burner based upon the determined fuel flow rate. The method further includes supplying the predicted amount of fuel to the burner.
