Abstract

본 발명은 환원제 공급장치 및 이를 이용한 배기가스 탈질시스템에 대한 것으로, 환원제를 선택공급부에 공급하는 환원제공급부와, 물을 선택공급부에 공급하는 물공급부와, 상기 환원제공급부와 물공급부로부터 공급받은 환원제와 물 중 어느 하나를 선택적으로 분사부에 공급하는 선택공급부와, 상기 선택공급부로부터 공급받은 환원제 또는 물을 분사하는 분사부를 포함하여, 상기 선택공급부는 상기 분사부가 환원제를 계속적으로 분사하는 과정이나 장치의 일시적인 고장에 의해 잔류하는 환원제의 고형화로 인해 막히게 되는 상기 분사부에 물을 공급하여 상기 분사부 막힘을 방지할 수 있는 것을 특징으로 하는 환원제 공급장치 및 이를 이용한 배기가스 탈질시스템을 제공하고자 한다.
