PURPOSE: A combustion type regeneration system for a diesel particulate filter is provided to effectively regenerate the diesel particulate filter, which falls into disuse or is in poor maintenance, thereby recycling a particulate matter collecting apparatus. CONSTITUTION: A combustion type regeneration system for a diesel particulate filter includes a combustor(3), a blower(2), a mass flow sensor(1), a first temperature sensor(4a), a second temperature sensor(4b), a first and a second oxygen sensor(7a,7b), and a regeneration controller(8). The combustor is installed at the upper portion of a particulate matter collecting apparatus in order to oxidize particulate matters accumulated on the particulate filter(6a). The blower supplies air for combusting fuel with the combustor. The mass flow sensor measures the mass of the air supplied to the blower. The first temperature sensor is installed between the combustor and the particulate matter collecting apparatus in order to detect whether or not the flame of the combustor disappears. The second temperature sensor measures the temperatures of the first temperature sensor, and the front and the rear of the particulate filter. The second temperature sensor is installed at the rear end of the particulate filter. The first and the second oxygen sensor measure the oxygen concentration of the particulate filter in order to adjust combustion conditions for the combustor. The regeneration controller controls fuel combustion conditions in the combustor.
