Manipulating coal produces dust, which spreads and settles around the transportation routes. High concentrations of coal dust particles and their settling in workplace can pose an explosion hazard. The biggest sources of coal dust in coal feeding applications are coal unloading in unloading pits, coal transport and transfer points, coal loading in boilers and filling bunkers.

If your dust collector has a single main duct, then only one zone is required. The air in the ducts is travelling at a very great rate of speed and therefore carries a spark or ember very rapidly. Air transport speeds of 6000 ft/min. are not uncommon which means a spark can be carried 100 feet in one second.
