THE EFFECT OF HYDROGEN AND AMMONIA COMBUSTION ON PERFORMANCE AND EMISSIONS

The co-combustion of traditional methane gas and alternative fuels importance to reduce emissions in combustion has been increased in recent years. In this study, the effects of the combustion of methane-hydrogen and methane-ammonia-hydrogen fuel mixture on system performance and emissions were numerically investigated. Firstly, the effects of methane and 5%, 10% and 15% hydrogen mixture were investigated. Then, methane and 5% fixed hydrogen ratio with 5% ammonia, 10% ammonia and 15% ammonia mixtures were examined. As a result of the study, combustion chamber temperature, carbon and NOX emissions are presented comparatively for each case. In addition, the Sandia D model used in the study is presented by verifying with the literature data. The findings obtained in the study showed that increasing hydrogen and ammonia increased NOX emissions while decreasing CO2 emissions. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
