METHOD AND APPARATUS FOR OPERATING AN EMISSION ABATEMENT ASSEMBLY

A method of operating an emission abatement assembly includes supplying a first flow rate of fuel to a fuel-fired burner to generate heat to combust soot trapped in a particulate filter. The method further includes supplying a second flow rate of fuel to the burner in an attempt to increase the temp...

Zusammenfassung:	A method of operating an emission abatement assembly includes supplying a first flow rate of fuel to a fuel-fired burner to generate heat to combust soot trapped in a particulate filter. The method further includes supplying a second flow rate of fuel to the burner in an attempt to increase the temperature of the heat with the second flow rate of fuel being greater than the first flow rate of fuel. The method further includes determining the temperature of the heat. The method further includes supplying a third flow rate of fuel to the burner if the temperature of the heat decreases in response to supplying the second flow rate of fuel with the third flow rate of fuel being less than the second flow rate of fuel. An associated emission abatement assembly is also disclosed.
