Abstract

This research focused on Liquefied Petroleum Gas combustion with ammonia (NH3) non-premixed flame on a slot burner which combustion characteristics were investigated for decrease of carbon dioxide (CO2). LPG combustion with flow variation of NH3, (LPG: NH3) was experimentally applied on slot burner to study flame shape, OH intensity, flame temperature, emission of NOx, CO and exhaust gas temperature. As the results, the flame color became blue-yellow due to NH2 radical from NH3 added in LPG combustion. Moreover, NH3 addition in LPG affected the combustion characteristics such as burning velocity, flame appearance, flame stability, flame temperature, NOx and CO emissions. This research was clarified that NH3 could be applied with LPG combustion and the lower burning velocity, blow off flame, unstable flame, lower flame temperature, higher NOx, lower CO and CO2 were achieved at less 60% of NH3 addition. © 2025, Thai Society of Mechanical Engineers (TSME).
