Title (EN) EXHAUST GAS POST-PROCESSING SYSTEM
(FR) SYSTÈME DE POST-TRAITEMENT DE GAZ D'ÉCHAPPEMENT
(KO) 배기가스 후처리 시스템
Abstract:
(EN) An exhaust gas post-processing system according to an embodiment of the present invention comprises: an exhaust flow path for moving an exhaust gas having been discharged from an engine; at least one post-processing device installed on the exhaust flow path to purify the exhaust gas; a burner installed on the exhaust flow path to heat the exhaust gas at an upstream of the at least one post-processing device; a fuel supply part for supplying a fuel to the burner; and an air supply flow path for supplying air to the burner. Further, the air supply flow path supplies, as the air, a part of the exhaust gas having been discharged from the engine to the burner.
(FR) Selon un mode de réalisation de la présente invention, un système de post-traitement de gaz d'échappement peut comprendre : un trajet d'écoulement d'échappement pour déplacer un gaz d'échappement ayant été évacué d'un moteur; au moins un dispositif de post-traitement installé sur le trajet d'écoulement d'échappement pour purifier le gaz d'échappement; un brûleur installé sur le trajet d'écoulement d'échappement pour chauffer le gaz d'échappement en amont du ou des dispositifs de post-traitement; une partie d'alimentation en carburant pour fournir un combustible au brûleur; et un trajet d'écoulement d'alimentation en air pour fournir de l'air au brûleur. En outre, le trajet d'écoulement d'alimentation en air fournit, comme air, une partie des gaz d'échappement ayant été déchargés du moteur au brûleur.
(KO) 본 발명의 실시예에 따른 배기가스 후처리 시스템은 엔진에서 배출된 배기가스를 이동시키는 배기 유로와, 상기 배기 유로 상에 설치되어 상기 배기가스를 정화시키는 적어도 하나의 후처리 장치와, 상기 배기 유로 상에 설치되며 상기 적어도 하나의 후처리 장치의 상류에서 상기 배기가스를 가열시키는 버너와, 상기 버너에 연료를 공급하는 연료 공급부, 그리고 상기 버너에 공기를 공급하는 공기 공급 유로를 포함한다. 그리고 상기 공기 공급 유로는 상기 공기로서 상기 엔진에서 배출된 배기가스의 일부를 상기 버너에 공급한다.
