Requirements for Explosion-proof Distribution Boxes in Coal Preparation Plants

Zone 20 requires equipment with the highest level of dust ignition protection, typically Ex ta or Ex tb enclosures with surface temperature limits appropriate for the specific coal type. Zone 21 permits Ex tb or Ex tc equipment, while Zone 22 allows Ex tc protection. Coal conveyor systems move millions of tons of material annually, and every transfer point, belt return, and drive station generates fine particulate that accumulates in enclosed galleries. When that dust reaches concentrations between 40 and 4,000 grams per cubic meter and encounters an ignition. Explosion-proof distribution boxes are mainly used in coal mines, fire stations, petroleum, petrochemical installations and textile a...
