Simulation numérique d'un bruleur à biogaz destiné aux moteurs Stirling
Main Article Content
Abstract
The design of a biogas burner for Stirling engines depends on its ability to provide a sufficient heat which is not produced by conventional burners because of the limitation of the contact surface between flame-hot head and the low methane content in the biogas. Therefore, a special microscale combustion chamber for this kind of burner is necessary. In this work, we studied numerically the biogas combustion by a Swiss-roll burner in a small-scale combustor. The temperature distribution versus the biogas injection rate is investigated. A significant increase of the flame temperature is obtained with an improvement of the uniformity of the temperature distribution and the burner efficiency.
