Explosion Vent For Coal Grinding Description

Engineered Explosion safety concepts for coal grinding plants

3) Protection of the fine coal bin: Explosion venting with EX-GO-VENT panel Due to the low vacuum conditions prevailing in the fine coal bin, SK-EGV single-layer vent panels including signalling units, are the perfect explosion protection of the coal bin. The quantity of vent panels depends on the bin size (volume) and pressure resistance.

At that point Thorwesten Vent had begun to work with explosion vents, predominantly for its own coal silos. We were then approached by others, such as Polysius and FL, which wanted to licence vents for their own designs. Learning about the use of explosion vents in collaboration with such firms led to applications in coal grinding equipment, including bag filters.

• Conventional explosion venting: Explosion venting is a technique for protecting sealed vessels that prevents the pressure within the vessel from rising above a permitted level. Breaking points, such as explosion discs or panels, in the walls of the plant rupture when the pressure reaches a predefined level and thus reduce the pressure in the vessel to a safe level.
