Abstract
Investigation results on combustion of methane and ammonia diluted with hydrogen are presented. The effect of hydrogen addition on the physicochemical properties, flame flashback conditions, and boundaries of stable combustion is determined over a wide range of fuel-air equivalence ratios (from lean to rich mixtures).
