Abstract According to one embodiment of the present invention, provided is a combustion system comprising: a combustion chamber; and a processing unit which processes combustion gas discharged from the combustion chamber. The combustion system comprises: a branch path which branches a part of the combustion gas in a path where the combustion gas discharged from the combustion chamber passes through the processing unit; and a spray apparatus which is configured to be connected to the branch path, receive the combustion gas of the branch path as recirculation combustion gas, make spray gas by mixing the recirculation combustion gas with a first reducing agent for removing nitrogen oxide (NOx) and a second reducing agent for removing nitrous oxide (N2O), and spray the spray gas into the combustion chamber. On an upstream side of the spray apparatus, the recirculation combustion gas is mixed with the first reducing agent, to evaporate and pyrolyze the first reducing agent. On the downstream side, the recirculation combustion gas is further mixed with the second reducing agent for forming the spray gas. The combustion system can minimize the post-processing process for removing nitrous oxide. 본 발명의 실시예에 따르면, 연소실과 이 연소실에서 배출되는 연소가스를 처리하는 처리부를 포함하는 연소 시스템으로서, 연소실에서 배출된 연소가스가 상기 처리부를 통과하는 경로에서 연소가스의 일부를 분기하는 분기경로; 및 상기 분기경로와 연결되어 분기경로의 연소가스를 재순환 연소가스로서 공급받아 이 재순환 연소가스에 질소산화물 제거용의 제1 환원제 및 아산화질소 제거용의 제2 환원제를 혼합하여 분사가스를 만들고 이 분사가스를 상기 연소실 내부로 분사하도록 구성된 분사장치;를 포함하고, 이 분사장치의 상류측에서 상기 재순환 연소가스에 상기 제1 환원제를 혼합하여 제1 환원제를 기화 및 열분해하고 하류측에서 상기 재순환 연소가스에 상기 제2 환원제를 더 혼합하여 분사가스를 형성하도록 구성된 것을 특징으로 하는 연소 시스템을 제공한다.
