The Influence of Small Additives of Alcohol Vapors on Combustion of Hydrogen and Methane in Air

The results of investigation of LADIES SKIRTS SUIT combustion of hydrogen-air and methane-air mixtures in the presence of small additives of ethanol, isopropanol, propenol in horizontal tubes are presented.The additives reduce the upper limits of flame propagation and the rate of flame propagation.The difference of inhibiting efficiencies of these alcohols corresponds to their ability to break the reaction chains of Western leathers hydrogen and methane combustion processes.In the mixtures, containing less than 15% of hydrogen the suppression of combustion does not occur.
