coal mill explosion vents

The Re-closing Door Method. Since most of the plant is located outside venting is not a major problem but they need to vent a lot of kinetic energy from the mills to filter to silos and prevent the reintroduction of flesh air after the explosion event to minimise subsequent fires or secondary explosions. The most popular choice for endurance and efficiency is the Thorwesten self re-closing vent doors and flame …
