On the Flammability Limit

Research output: Contribution to journalArticlepeer-review


The upper flammability limit of ethane–air and ethane–oxygen mixtures was determined experimentally for various initial temperatures and pressures. In the 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 the quenching of the flame propagating downward after its rise under the action of the Archimedes force.
