Ignition temperature of combustible liquids in mixtures of air with nitrous oxide

Abstract

Summary While ignition temperatures in the air are well known for a large number of flammable substances and to a lesser extent in pure oxygen too, no such values exist for ignition temperatures in nitrous oxide in spite of the fact that nitrous oxide is used as oxidizer in combustion processes or aerosol propellant in industry. The ignition temperatures of some pure compounds have now been investigated in oxidizer mixtures of nitrous oxide and air with varying concentration of nitrous oxide up to 80 vol% using a slightly modified standardized apparatus. The ignition temperature increases with increasing nitrous oxide concentration. Up to 580°C, none of the investigated substances ignited in pure nitrous oxide.

“…Later, a comparative study, conducted by Deng et al using a high-pressure shock tube, refers to the influence of N 2 O and O 2 on ignition delay times of C 2 H 4 /O 2 /N 2 O/Ar and C 2 H 4 /N 2 O/Ar mixtures. Furthermore, Mitu et al , reported data about the ignition temperature of mixtures of combustible liquids with air enriched with O 2 or N 2 O.…”
