| ABSTRACT |
|
In order to investigate the regeneration effect of non-thermal plasma injection (NTPI) technology on fouled exhaust gas recirculation (EGR) cooler, NTPI regeneration apparatus and EGR cooler performance test system were built up. Results showed that non-thermal plasma (NTP) could peel off the deposit layer and improve the heat exchange performance effectively. The carbon removal energy efficiency of this NTPI regeneration setup was 22.46 g/kWh and the O3 utilization ratio was 96.50%. To get a deeper understanding of the regeneration effect, thermo-gravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) were introduced to investigate the variation of deposit layer |
