Abstract

The upper flammability limit of ethane-air and ethane-oxygen mixtures for various initial temperatures and pressures was determined experimentally. In experiments, the upper flammability limit increased with increasing initial temperature and pressure, which is consistent with literature data. The limit was determined in a closed vessel with central ignition. The obtained limit corresponds to quenching of the flame during its downward propagation after rise under the action of the Archimedes force.
