Combustion parameters of gaseous epoxypropane/air in a confined vessel

► Combustion pressure and temperature of epoxypropane/air reach highest at concentration 7%. ► Ignition energy has significant impact on upper flammability limitation of epoxypropane/air. ► Combustion pressure of epoxypropane/air reaches highest near lower flammability limitation. ► Combustion temperature of epoxypropane/air reaches highest near lower flammability limitation.
