Heat Recuperation from Internal Combustion Engines by Fuel Reforming: Kinetics-Based Analysis

چکیده
In an effort to estimate the feasibility of heat recuperation from internal combustion engine (ICE) by steam reforming (SR) or decomposition fuel, we study here required size a reformer exchanger in order power 3.7 kW engine. To that end, experimentally test transfer structured commercial reactor with ∼0.39 m2 area ∼1 L unit. We then simulate length for evaporation and several fuels, using published kinetics highly active catalyst, under fixed exhaust temperature 973 K, effect pressure steam-to-fuel ratio. Both co- counter-current schemes are considered. Methanol is probably best solution energy point view. However, it known lead deactivation. SR (with S/M = 1) requires about 2 reformer-HE seems be reasonable solution, yielding chemical gain ∼16%, value close asymptotic thermodynamic value. Moreover, presence CO2 reformate mitigate NOx emissions down zero-impact levels. Ethanol S/E 1 3) yields poor results since CH4 intermediate, which high temperatures reforming; operating ESR ∼1250 °K higher. While such may attained yield energetic more than 20%, will require modification process. Methylal (S/MA good as well.

متن کاملHeat Transfer in Internal Combustion Engines
A heat transfer model has been developed that uses quasi-steady heat flux relations to calculate the heat transfer from combustion gases through the cylinder wall to the coolant in an internal combustion engine. The treatment of convective heat transfer accounts for the physical problems of rotating and impinging axial flow inside the engine cylinder. The radiative heat transfer includes gas ra...
