Award Adolphe Van Tiggelen 2018 to Maxime Pochet

THE BELGIAN SECTION OF THE COMBUSTION INSTITUTE GRANTED THE “AWARD ADOLPHE VAN TIGGELEN” 2018 TO MAXIME POCHET (UCL-IMMC/VUB) FOR HIS EXCELLENT ORAL PRESENTATION AND THE SCIENTIFIC QUALITY OF HIS WORK ON “INVESTIGATION OF AMMONIA IGNITION DELAY AT LOW TEMPERATURES AND LEAN CONDITIONS”


For long-term electricity storage, part of the excess renewable energy can be stored into various fuels, among which ammonia and hydrogen show a high potential. To improve power-to-fuel-to-power overall efficiency and reduce NOx emissions, the intrinsic properties of Low Temperature Combustion (LTC) engines could be used to convert these carbon-free fuels back into electricity and heat. Yet, ignition delay times for ammonia are not available at relevant LTC conditions. This lack of fundamental kinetic knowledge leads to uncertain ignition delay predictions by the existing ammonia kinetic mechanisms and prevents from determining optimal LTC running conditions. Using a Rapid Compression Machine (RCM), this research studies the ignition delay of ammonia with hydrogen addition under LTC conditions and compared the data with simulation results obtained with five kinetic mechanisms found in the literature. It then provides a sensitivity analysis to highlight the most influencing reactions on pure ammonia ignition delay and suggests improvement directions.
