Abstract
A particulate removing device comprises a regenerating burner connected via an interrupting valve to a mixer subsequently connected to a particulate filter. The interrupting valve may be disposed in a housing for the burner on that end portion connected to the mixer through an exit to open and close the exit. When the burner generates a combustion gas, the valve opens the exit to permit the combustion gas to enter the mixer where it is mixed with an exhaust gas from a Diesel engine. The mixed gas heats and regenerates the particulate filter. When the burner is not used, the valve closes the exit to prevent the exhaust gas from the mixer from partly entering the burners housing. Alternatively, the interrupting valve may be disposed in a housing for the mixer on that end portion connected to the burner's housing through an exit to open and close the inlet.
