Thorwesten-Vent - Explosion protection for coal grinding

Thorwesten-Vent - Explosion protection for coal grinding

In a wide variety of industries, e.g. in the cement and steel industry, an explosive dust atmosphere is created during the grinding of coal and similar products. This can lead to explosions and therefore requires the consideration of constructional explosion protection measures in the form ofInterview - Coal Mill Safety,Learning about the use of explosion vents in collaboration with such firms led to applications in coal grinding equipment, including bag filters. On the surface this appears to be quite simple but the situations are quite different. The inside of a silo is big and wide, which means the explosion front propogates relatively slowly. By contrast, inside the narrow ducts of a coal grinding and de-dustingState-of-the-art explosion protection for dedusting of,,01/11/2010· Summary: With dedusting of coal grinding plants, the state of the technology is determined by the explosion protection measures, the filtration performance and the design of the plant. To ensure safe operation of a plant, only certified and tested concepts and components should be used for its design and manufacture.
