摘要
Energy extraction from an adiabatic regenerative porous burner is studied numerically. Steady state governing equations are solved to predict the fluid and thermal properties of the system. The temperature of heat extraction is varied from 300 K to 1300 K. The numerical simulation predicts the effect of efficiency of energy extraction on the location and extraction temperature of heat exchangers. Higher extraction temperatures tend to decrease the extracted energy and consequently raise the exhaust temperature of the burner. Two burner configurations are studied comparatively by changing the properties of the wall separating the incoming reactants from the exhaust gases. Out of the two materials used to study the effect of separation wall on energy extraction, the study predicts higher gains for alumina as compared to silicon carbide. The maximum heat extraction efficiency of 35% is reported for extraction at 1300 K when silicon carbide separation wall is used in the burner. Whereas for porous burner with alumina separation wall, 60% of the heat can be extracted at 1300 K. (C) 2018 Elsevier Ltd. All rights reserved.
