SELF-IGNITION OF HYDROCARBON-AIR GASEOUS-MIXTURES

The self-ignition temperatures and pressures of propylene/air gaseous mixtures were measured in a static installation (by admission method). For temperatures between 500 ... 750-degrees-C the self-ignition pres sures range within 600... 150 mmHg, depending on propylene concentrati on: the increase of the explosion vessel diameter entails the decrease of self-ignition temperatures and pressures. The correlation between the self-ignition parameters established on the basis of thermal explo sion theory was employed in the evaluation of some overall kinetic par ameters.
