EXHAUST FLOW SEGREGATOR AND ASSOCIATED SYSTEMS AND METHODS |
摘要 |
According to one embodiment, an exhaust gas after-treatment apparatus includes an exhaust tube (104) defining an exhaust flow channel through which a main exhaust gas stream is flowable. The apparatus also includes an exhaust flow segregator (117) positioned within the exhaust tube. The exhaust flow segregator separates the exhaust flow channel into a first channel (109) through which a first portion (240) of the main exhaust gas stream is flowable and a second channel (111) through which a second portion (250) of the main exhaust gas stream is flowable. Additionally, the apparatus includes an injector (108) coupled to the exhaust tube. The injector can inject reductant into the first portion of the main exhaust gas stream flowing through the first channel. At least one exhaust gas heater (110) is communicable in heat supplying communication with the first portion of the main exhaust gas stream flowing through the first channel. |
