DESIGN OF NOVEL RADIANT BURNER WITH HELICAL COMBUSTION CHANNELS

Abstract

Nowadays, Liquefied Petroleum Gas (LPG) burners are widely used in households and industries. The conventional LPG burners work on Free Flame Combustion and have lower thermal efficiency, lower turn-down ratio and emit higher emissions compared to the burners based on newer technologies such as Porous Media Combustion (PMC). Porous media combustion is characterized by higher flame speed, wider flammability limit and high radiant output. Innovative 3D metal and ceramic additive printing techniques allow for the manufacturing of porous media with helical combustion channels instead of the typical sponge like matrices used in porous media burners. The presence of helical combustion channels induces secondary flows, which increase the heat transfer rate of combustion to the nearby solid matrix. In this work, CFD analysis of a radiant burner with helical combustion channel is done with the help of ANSYS fluent
