  It is shown that spark initiated flames of lean hydrogen-air mixtures (8%-15% Ð�2) pass through close-meshed aluminum spherical obstacles with the cell size 0.04-0.1 mm2; the flame of 15% Ð�2 in air after an obstacle is accelerated; acoustic gas fluctuations occur in the reactor. The flame of 7.5% hydrogen-air mixture does not propagate through the obstacles the flame of 8% natural gas-air mixture is not accelerated after an obstacle; acoustic fluctuations are missing. It is shown that active centers of methane and hydrogen combustion, determining flame propagation, have different chemical nature. .. View More»
