for gas detection systems to be used to limit concentrations. When the process is closed and the level of flammable gases or vapours is allowed to exceed the LEL level, this is acceptable as long as the oxygen concentration is kept low enough to control the risk of explosion (inertisation). If these measures however are not sufficient, all of the involved electrical devices have to be designed ...

Combustion: The burning gases produce combustion at or near the surface of the bulk plastic and the process can become self-sustaining if it produces sufficient energy.

Die Mindestzündenergie (MZE) E min. ist eine sicherheitstechnische Kenngröße zur Beurteilung der Zündfähigkeit explosionsfähiger Atmosphären. Sie beschreibt die niedrigste Energie, die bei einer Entladung ausreichend ist, um ein explosionsfähiges Brennstoff-Luft-Gemisch in seiner zündwilligsten Zusammensetzung zu entzünden.

There is however, a direct relationship between moisture content and minimum energy required for ignition, minimum explosive concentration, maximum pressure, and maximum rate of pressure rise. For example, the ignition temperature of cornstarch may increase as much as 122oF, with an increase of moisture content from 1.6 percent to 12.5 percent. As a practical matter, however, moisture content ...

MINIMUM IGNITION ENERGY The minimum ignition energy (MIE) has been extensively investigated for many combustible mixtures. For gaseous mixtures, the MIE is a definite quantity which depends on the type of fuel, on fuel concentration, and to a lesser extent, on the elec- trode configuration.

Ignition of hydraulic fluid sprays by open flames and hot surfaces ... Most hydraulic fluids are combustible and are used under high pressure to transmit power or motion. Pressurized oil in hydraulic systems presents a considerable fire hazard, particularly where ignition sources are present. When hydraulic oil is released under pressure, it often results in an atomized spray or mist of oil ...
