Beschreibung
Zusammenfassung:	An exhaust gas device according to an embodiment of the present invention includes a DOC/DPF module for removing particulate matter (PM) contained in exhaust gas; a regenerative burner module disposed at a front end of the DOC/DPF module for heating; an SCR module disposed at a rear end of the DOC/DPF module to remove nitrogen oxides contained in the exhaust gas using a reducing agent; and a control module for controlling driving of the regenerative burner according to an injection amount of the reducing agent and the temperature of the exhaust gas. An objective of the present invention is to provide the exhaust gas device and the exhaust gas reduction method that simultaneously reduce PM-NOx by increasing the efficiency of SCR using a regenerative burner. 본 발명의 일 실시예에 따른 배기가스 장치는 배기가스에 포함된 입자상 물질(PM)을 제거하는 DOC/DPF 모듈, 상기 DOC/DPF 모듈 전단에 배치되어 가열하는 재생버너 모듈, 상기 DOC/DPF 모듈 후단에 배치되어 환원제를 이용하여 배기가스에 포함된 질소산화물을 제거하는 SCR 모듈, 및 상기 환원제 분사량 및 배기가스의 온도에 따라 상기 재생버너의 구동을 제어하는 제어모듈을 포함한다.
