Abstract

In this paper, an attempt has been made in order to investigate the key parameters that have an effect on the porous media burners. The aim of this work was to reduce the pollutants emitted from the burner and to enhance the efficiency of the combustion chamber. Improvement of different combustion chamber components in burners includes the enhancement of combustion chamber efficiency and the reduction of shape factor which cutbacks the production of pollutants and enhances fuel consumption and is an important criteria both in economical and environmental aspects. To obtain these objectives, a comparison has been made between the numerical work of the present study and experimental work conducted by other workers. The burner under this study consists of two parts, a preheater and combustion chamber where methane and air are premixed in the chamber. From the findings of these studies it was revealed that by employing semi- porous burner, the burner's performance could be improved. The results Show reduction of NOx Pollutant in the new geometry of porosity matrix comared with uniform Porosity matrix.
