Abstract
The results of an experimental study of the normal flame propagation speed of a hydrogen-enriched and/or water vapor-diluted methane-air mixture at atmospheric pressure and initial mixture temperatures of 300 and 330 K are presented in this paper. The normal flame propagation speed was determined by the zero heat flow method (Heat Flux). The obtained experimental data were compared with the results of numerical simulation of adiabatic premixed laminar flames, which was carried out using three kinetic mechanisms of the methane-hydrogen fuels oxidation. The flame speed increased proportionally up to 35% when the methane was enriched with hydrogen up to 35% by volume. With increasing vapor concentration, a linear decrease in the flame speed of the methane-air mixture was observed. This decrease does not depend on the degree of hydrogen enrichment. Recommendations are proposed for the use of kinetic mechanisms to simulate the flame of a methane-air mixture when it is enriched with hydrogen and diluted with water vapor.
