Coal, Cement & Steel: Dust Explosion Venting
THE VERY BEST IN EXPLOSION VENTING FOR THE COAL, CEMENT AND STEEL INDUSTRY
The cement and steel industries have a long association with coal as a source of fuel. They are now using more sustainable alternative fuels from tyres to sludge pellets.
Learn how to protect your process with the right explosion protection solutions for your specific plant.
CEMENT, STEEL, COAL & SUSTAINABLE ENERGY: VENTING DOORS
THE SELF RE-CLOSING DOOR VENT SYSTEM
Since most of the plant is located outside, venting is not a major problem. We need need to vent a lot of kinetic energy from the mills, the filter and the silos. It is critical to 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 TV self re-closing vent doors and flame diverters. Vent 1 vents the primary explosion force reducing the velocity to the filter. Vent 2 diverts the resultant flame from the filter intake.
The Filter and silo are then vented as individual components without the concern from flame jet ignition and pressure pilling. Many of these systems are further protected by inerting using Nitrogen or CO2.
