- 摘要：
An embodiment of the present invention relates to a selective catalytic reduction system. The selective catalytic reduction system comprises: a main exhaust flow path in which an exhaust gas containing a nitrogen oxide moves; a reactor installed in the main flow path and including a catalyst for reducing the nitrogen oxide contained in the exhaust gas; a urea decomposition chamber for decomposing urea and generating ammonia; an ammonia injection part for injecting the ammonia generated from the urea decomposition chamber into the exhaust gas to be introduced into the reactor; a urea direct injection part for directly injecting the urea into the exhaust gas to be introduced into the reactor; a urea supply part for supplying urea to the urea decomposition chamber or supplying urea to the urea direct injection part; a diverging flow path which diverges from the main exhaust flow path in the front of the reactor and is connected to the urea decomposition chamber; a blower, installed in the diverging flow path,
