No Big-Bang in Wood Processing

An explosion in a wood processing plant may endanger human lifes and the environment as well as the survival of the plant.
Innovative Explosion Protection for Wood-processing Plants
Since the re-discovery of regenerative energy sources wood processing has seen a considerable growth due to the demand of easy to handle fuel. In view of the ignitability and explosibility of the developing wood dust provisions must be taken to minimize/prevent the impacts of dust explosions.

Recycling – certainly safely!

Metal is recovered from residues in four melting furnaces.
How to avoid Fires downstream of a “fiery” Process
During the recycling of scrap-metals a certain amount of dust is produced. Especially, when the recycling process involves pyrometallurgical steps there is the risk of glowing embers being transported into the filters, where they may ignite serious fires.

Considerations about the Cost of Conveyor Belting – Discussing re-evaluated Belt Safety Factors

Safety Factors for Conveyor Belts
New conveyor belts and belt monitoring technologies reduce conveyor belt capital and operating costs by using lower belt strengths than previously thought possible. Key factors are improvements in splice performance, rubbers and real-time belt condition surveillance systems.

“Clean” Recycling with Atomized Dust Suppression

RAI has successfully employed an atomized mist system to suppress dust in and around its Chula Vista plant.
Dust Control
Reducing the need to landfill huge amounts of reusable debris from road repair includes the processing of these materials during which a great amount of dust is produced. A California company solved its dust problems with an special water mist generator. At first, the company tried to reduce the amount of dust with a sprinkler system. But that just saturated the material and creating a lot of mud, whereas the dust still remained an issue.

Bag House Operation Problems

Dust Collection
More stringent air-pollution laws are drawing more attention to the off gas cleaning facilities of industrial and power plants. Nowadays, bag filters are gaining more and more attention also in medium and high temperature applications. Typical problems arising from physical function and chemical impact will be featured in this article.

If the Belt is on Fire

Burning belts do not only mean production losses, but often also a thread for personnel and equipment.
Belt Conveyor Safety
Playing with fire!? - Belt conveyors are sophisticated equipment widely used in the transportation business. Most often, nevertheless, their function is of paramount importance for the plants they serve: If the belt conveyors fail, the plant (or port) might be paralysed, so their weaknesses should always be kept in mind.

Explosion Control in Elevators

Vertical Conveying
Conveying systems for bulk solids are often at risk of explosions. as it is almost impossible to avoid this risk, there have to be technical installations which reduce the outcome of such an event. One of the most effective anti-explosion systems for vertical conveyors is an explosion suppression system.
