Waste Energy: Powder Explosion Suppression Venting Isolation Silos Filters Elevators Mills Pipelines


As the wet mix sludge starts moving down the Drum Dryer to the discharge screw, it becomes dryer but also potentially more unstable. If the product is thermally unsafe it is discharged to a safe bin outside or cooled in a series of cooling screws before being lifted to the Sifter for grading into different sizes.  This is where the risk is at its highest. Protection should be  chemical barriers along the screws with venting either to a safe area outside or if that not’s possible, flameless venting inside the building. Good house keeping is important as sludge pellets are a fuel source and dispersion of the dust layers is to be avoided.


General terms for this industry are: Waste Water Treatment and Bio-Mass, Waste to Energy, Municipal waste, Car Shredders, Land Fill replacement Plants, Meat and Bone meal, and these are now becoming the biggest growth in Green field installations, as countries come to terms with their waste problems.  Processes handling a combination of Dust, Gas and Vapour hazards are beginning to be developed, requiring the full range of Explosion prevention and protection systems available.
