Level Measurement Solutions for Coal Storage and Containment

Although some power plants are now fueled by renewable energy sources, coal-fired power plants are still a staple of the power industry. One important aspect of managing a coal-fired plant is ensuring safe coal storage.

Magnetrol® has produced an applications brochure for the power industry, detailing measurement challenges and solutions for each step of the power generation process. This blog post is part of an occasional series exploring each application in detail.

Level Measurement Challenges and Considerations

Raw coal is delivered to a coal yard in aggregate pieces of approximately 6″ that are later reduced in size by a crusher to approximately 1.5″. Enclosed storage of crushed coal is common in frigid climates and where containment of coal dust is controlled to protect populated areas. Hoppers and silos store active and reserve crushed coal prior to its pulverization into the powdered form suitable for boiler combustion.

Some severe power plant accidents in years past have been traced to coal dust ignition, and the atmospheres of contained coal storage areas are highly congested with explosive dust. For safe coal yard operation, explosion-proof, airtight level instrumentation is absolutely essential.

Level Instrumentation Solutions

MAGNETROL has produced a level instrumentation solution for safer coal storage:

  • Solitel® vibrating rod level switch, available with an extended rigid probe up to 100 inches (254 cm) or an extended flexible probe up to 65 feet (20 meters)
