We investigated burning velocities of stoichiometric hydrogen-oxygen-steam mixture as basic data for a future electric power plant with a hydrogen combustion turbine. At first burning velocities under atmospheric pressure are experimentally measured by burner method. Those of hydrogen -oxygen-steam mixtures are smaller than those of argon mixtures. Burning velocities of both mixtures increase with initial temperature and hydrogen concentration, but burning velocities of steam mixtures are more strongly influenced by initial temperature than those of argon mixtures. The data measured under atmospheric pressure gave rough agreement with the value obtained by theoretical calculation using chemkin II. Then we estimated burning velocities of stoichiometric hydrogen-oxygen-steam under high temperature and high pressure circumstances. Burning velocities of steam mixtures significantly decrease even under 600℃ circumstance with increasing pressure, but accuracy of estimated burning velocities under high pressure circumstance is worse than that under atmospheric pressure.
