Level Measurement of Raw Coal Piles at Coal-Fired Power Plants
Accurately measure pile levels of raw coal with non-contacting radar despite the challenge of irregular surfaces.
Level Monitoring with Non-contacting Radar and Point Level Technology
In raw coal yards or warehouses, raw coal is delivered in aggregate pieces of approximately 15 cm (6 in). Pieces are later reduced in size by a crusher to approximately 4 cm (1.5 in). The raw coal is stored in stock piles which have irregular surfaces and can cover large areas, making reliable level-measurement a challenge.
