<P>PROBLEM TO BE SOLVED: To provide a post-treatment burner system including a burner which continues combustion even when an exhaust brake operates. <P>SOLUTION: The post-treatment burner system has: a particulate filter 12 (exhaust cleaning material) provided downstream from the exhaust brake 21 in an exhaust pipe 11; a burner 14 provided on an inlet side of the filter so as to appropriately heat the filter; an air supply pipe 19 introducing a part of intake air 4 from the downstream of a compressor 2a of a turbocharger 2; and a stop valve 20 (a first stop valve) provided in the middle of the pipe and appropriately cutting off the flow of the intake air 4. A communication pipe 22 extracts a part of the exhaust from the upstream of the exhaust brake 21 of the exhaust pipe 11, and introduces the flow of the exhaust to the downstream of the stop valve 20 of the air supply pipe 19. A stop valve 23 (a second stop valve) appropriately cutting off the flow of the exhaust in the communication pipe 22, and an orifice 24 for preventing excess extraction of the exhaust to the communication pipe 22, are installed in the communication pipe 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
