Experimental study of fundamental combustion characteristics for ammonia/hydrogen/air flames

Abstract

Hydrogen and ammonia, which can be produced from hydrogen, are expected to be put to practical use as zero-carbon fuels in the near future. However, basic research knowledge is needed for the practical application of large marine engines. In this study, the fundamental combustion characteristics of hydrogen-ammonia fuel mixtures were systematically investigated under various combustion conditions through experiments using a constant volume combustor.
