Coal-fired power plants rely on conveyor systems to haul ash from their boilers for disposal and allow for continuous coal burning and steam production. At a United States plant, ash slurry leaking from the conveyor was compounding maintenance costs, creating a hazard and increasing the risk of equipment failure. Inpro/Seal Smooth Bore Air Mizer seals provided the answers. To cool ash before disposal, it is sprayed with water as it comes out of the boiler. The combination of ash and water creates ash slurry. While the ash conveyor system is enclosed to contain the slurry, there are potential leakage points at the two shafts driving the conveyor belt. To seal those shafts, the power plant was using packing.
