Coal Pulverization System: Explosion Prevention and

 · The explosion characteristics are shown in Table 1. The ignition energy of the coal powder is 50mJ, so electrostatic and mechanic sparks should be considered as ignition sources. The explosion index K max is less than 10 MPa.m/s, so venting and suppression are effective for the coal powder. Table 1: Explosion characteristics of the coal powderRapid reactive synthesis of TiAl3 intermetallics by · Porous TiAl 3 intermetallics were synthesized from Ti-75 at.% Al elemental powder mixtures using an energy-saving and rapid reactive method of thermal explosion (TE). The results demonstrated that the actual temperature of the compact climbed rapidly from 673 °C to 1036 °C within 24 s, indicating that an obvious TE reaction occurred during sintering process.Rapid reactive synthesis of TiAl3 intermetallics by · Porous TiAl 3 intermetallics were synthesized from Ti-75 at.% Al elemental powder mixtures using an energy-saving and rapid reactive method of thermal explosion (TE).

Basic concepts for explosion protection

 · Basic concepts for explosion protection Harmonization of explosion protection Internationally, the standpoints on the explosion protection of electrical and non-electrical equip-ment are co-ordinated by specialized IEC and ISO working groups. In the area of electrical engineering, internationally harmonized design agreementsEstimation of the critical external heat leading to theand thermal runaway can be a potential ignition source for such mixtures [2, 3]. A more reliable Li-ion battery and its safe use can help reduce the risks of fire and explosion accidents in underground mines. Many studies have been performed to investigate the thermal stability of Li-ion batteries.
