COMPARATIVE STUDY HAVING IN VIEW THE METHODS OF DETERMINATION THE MINIMUM IGNITION ENERGY OF THE AIR/COMBUSTIBLE DUST MIXTURES
Abstract
Explosive mixtures generated in technological installations by processing, handling and storage are generally complex and in many cases cannot be assimilated with existing specific data. When ignited, they can burn rapidly and result in a considerable explosion force, when in mixture with air in proper proportions. Therefore, for establishing with certainty the requirements of the technical equipment which can be used in potentially explosive atmospheres generated by air / combustible dust mixtures, it is necessary to know the type of dust, as well as a series of parameters defining its sensitivity to ignition by different sources, defined as the minimum ignition energy ? MIE. One of the ignition sources of the explosive dust / air atmosphere is electrostatic discharge. The ignition risk assessment of the explosive mixture by electrostatic discharge is done by comparing the electrostatic discharge energies with the minimum explosive atmosphere ignition - MIE. Therefore, knowledge of the minimum ignition energy of processed, transported or stored dusts in installations is very important in the process of ignition risk assessment and for establishing the measures for explosion prevention and / or protection. This paper presents a comparative study having in view the methods used for the determination of the minimum ignition energy of the air/combustible dust mixtures with different apparatus on the same types of dust. By knowing this parameter of the air/combustible dust mixtures, there can be correlated the protection / prevention measures and the safety features according to the specific application.
