Case Study Of Coal Dust Explosion In Thermal Power Plants

  • Inspection Door - Martin Eng

    This power plant had dust and spillage escaping from the coal-handling systems. To boost material-handling efficiency and reduce the risk of fire or explosion, Martin installed taller and longer skirtboard walls, new belt support systems, abrasion-resistant wear liners, and a multi-layer, low-pressure sealing system on the outside of the chute walls.
