Explosion Characteristics of Propanol Isomer-Air Mixtures

Popis výsledku v původním jazyce

This paper describes a series of experiments performed to study the explosion characteristics of propanol isomer (1-propanol and 2-propanol)-air binary mixtures. The experiments were conducted in two different experimental arrangements-a 0.02 m3 oil-heated spherical vessel and a 1.00 m3 electro-heated spherical vessel-for different equivalence ratios between 0.3 and 1.7, and initial temperatures of 50, 100, and 150 oC. More than 150 pressure-time curves were recorded. The effects of temperature and test vessel volume on various explosion characteristics, such as the maximum explosion pressure, maximum rate of pressure rise, deflagration index, and the lower and upper explosion limits were investigated and the results were further compared with the results available in literature for other alcohols, namely methanol, ethanol, 1-butanol, and 1-pentanol. The most important results from evaluated experiments are the values of deflagration index 89-98 bar.m/s for 2-propanol and 105-108 bar.m/s for 1-propanol/2-propanol-air mixtures. These values are used to describe the effect of isomer blends on a deflagration process and to rate the effects of an explosion.
