| 摘要 |
The present invention relates to a power apparatus with a selective catalytic reduction system capable of reducing an installation space and maintenance costs by efficiently reducing nitrogen oxide contained in the exhaust gas discharged from multiple engines. According to an embodiment of the present invention, the power plant of the invention comprises: a first engine discharging exhaust gas containing nitrogen oxide (NOx); one or more second engines discharging exhaust gas containing nitrogen oxide (NOx) having a higher temperature than that of the first engine; a first exhaust flow passage through which the exhaust gas of the first engine flows; a second exhaust flow passage through which the exhaust gas of the second engine flows; a first reactor including a catalyst reducing nitrogen oxide included in the exhaust gas which is installed in the first exhaust flow passage; a second reactor including a catalyst reducing nitrogen oxide included in the exhaust gas which is installed in the second exhaust flow passage; a first reducing agent injection unit injecting a reducing agent into exhaust gas flowing toward the second reactor; and a single decomposition chamber generating a reducing agent to be supplied to the first and second reducing agent injecting units. |
