Abstract: An exhaust component includes a housing defining an internal cavity and a burner positioned within the internal cavity. The burner provides a combustion chamber having an exhaust gas inlet, a fuel inlet, a combustion air inlet, and an outlet. At least one exhaust aftertreatment component is positioned within the internal cavity and is directly coupled to the outlet of the combustion chamber.

Abstract: According to one aspect of the disclosure, 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. The method further includes 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.
