MIE - Minimum Ignition Energy of dust
The humidity is also important, as well as the temperature. Finally, one key parameter is actually the size of the powder. Indeed, the MIE varies along the cube of the diameter of the dust : MIE = f(d 3) This means that the smaller the particles are, the lower is the MIE and the higher will be the dust sensitive to an ignition source. This dependency is important to interpret and understand,Fire Detection Methods for Coal Pulverizer Systems,study concluded that reducing the frequency of fires would reduce the risk of coal dust explosions. Unfor- tunately, less than 15 percent of the power plants have adequate fire detection systems for coal mills. The small group that has implemented different detection techniques has created a controversy over the reliability and effectiveness of detection methods. The EPRI project studied four,Dust explosions explained | Characteristics, ignition and,,Conditions for an Explosion A dust cloud of any flammable material will explode where: 1 the concentration of dust in air falls within the explosive limits, and 2 a source of ignition of the required energy for that dust cloud is present. Conversely, an explosion can be prevented if one, or preferably both, of these conditions are avoided.
