DETERMINATION OF EXPLOSION PARAMETERS FOR AIR-GASOLINE MIXTURES.

The explosive atmosphere may be caused by flammable gases, vapors, or combustible dust. In the event that the material is combined with air in an adequate proportion, an ignition source is required to produce an explosion. Fuels and other liquids, as well as solvents from industrial items, release volatile vapors that can catch fire or explode when they come into contact with the air. At normal temperatures, flammable liquids can emit enough vapor to form combustible mixtures with air, heat, and often thick, black, and toxic clouds of smoke. The potential causes of explosions within work systems are represented by the intrinsic properties of flammable/combustible chemical substances and preparations used, dangerous chemical reactions, energy sources, or the ability of technical equipment, work methods, or techniques to cause human or material damage. Understanding the characteristic explosive parameters in regulated settings is essential to evaluating the risk of explosion and the evolution of explosion in such mixtures. In this paper maximum explosion pressure p_max and maximum rate of pressure rise (dp/dt)_max for gasoline-air mixtures were determined in a standard 20 dm³ spherical explosion vessel in order to validate in the laboratory the method of determining the explosion parameters of air-vapor mixtures.
