재연소장치가 장착된 디젤엔진 열병합 시스템의 효율 향상에 관한 연구

As a kind of distributed energy system, the co-generation system based Diesel engine using after-treatment device was devised for its environmental friendly and economic qualities. It is utilized in that the electric power is produced by the generator connected to the Diesel engine, and shell & tube heat exchangers. A after-treatment device composed ceramic heater and DOC(Diesel Oxidation Catalyst) is installed at the engine outlet in order to completely reignite the unburned fuel from the Diesel engine, thereby improving a system’s efficiency of maximum 93.6% as well as reducing air pollution due to exhaust gases.
