시스템 유입구, 기체 유동 시스템 및 복수의 촉매 클러스터를 포함하는 소형의 선택적 촉매 환원 시스템 (SCR)이 기재된다. 시스템 유입구는 정화된 배기물의 열을 사용하여 환원제 또는 환원제 전구체의 용액을 기화시키고, 기화된 환원제를 배기 가스와 혼합하여 혼합 기체를 형성하도록 구성된다. 기체 유동 시스템은, 시스템 유입구로부터의 혼합 기체를 복수의 촉매 클러스터로 제공하고, 배기 가스로부터의 열을 환원제/전구체의 기화를 보조하고 전구체의 환원제로의 전환을 보조하기 위해 제공하도록 구성된다. 복수의 촉매 클러스터는 SCR 및 ASC 촉매를 포함하지만, 필터 기능을 포함할 수도 있다. A compact Selective Catalytic Reduction (SCR) system comprising a system inlet, a gas flow system and a plurality of catalyst clusters is described. The system inlet is configured to utilize heat of the cleaned exhaust to vaporize a solution of a reductant, or a precursor of a reductant, and to mix the vaporized reductant with exhaust gas to form a mixed gas. The gas flow system is configured to provide the mixed gas from the system inlet to a plurality of catalyst clusters and to provide heat from the exhaust gas to assist in vaporization of the reductant/precursor and to assist in the conversion of the precursor to the reductant. The plurality of catalyst clusters comprise SCR and ASC catalysts but can also include filter functionality.
