Better venting boosts protection against dust explosion

11 November 2008

Many industrial processes consistently generate considerable quantities of fine dust, which starts as ‘just’ combustible but becomes highly explosive when enriched with oxygen. An ignition source in the plant can then set off an explosion with enormous damage to machinery and men.

Although ATEX directive 94/9/EG obliges operating companies to carry out primary explosion protection, compliance only statistically reduces the odds of a disaster while still leaving the dust explosion risk itself still in place.

ATEX therefore strongly requests additional constructive explosion protection in plants operating with fine dusts, and the addition of explosion venting with relief panels approved by the directive provides the ideal solution. If a dust explosion occurs, its pressure is reduced to a harmless level within in the plant.

These relief panels must resist operating pulsations and temperature changes, corrosive environments and the early material fatigue of some makes which experience shows endangers safety and causes costly plant shutdowns.

‘Ex-Go-Vent’ explosion relief panels from REMBE of Germany and now available in the UK from Orthos distinguish themselves by bionic structures which eliminate all such operational problems. Approved to FSA 04 ATEX 1538X, their unique patented design guarantees durability and an exceptionally long working life under all production conditions.

Combining the user benefits of full plant availability and simplified installation with considerable cost savings, these flat single-layer panels give 100% venting efficiency. They are available in 25 different standard dimensions for a wide range of applications.

Quick and easy mounting is ensured by a patented concept of combined gasket and breaking point configuration that eliminates the need to control the clamping torque of the fixing bolts that is required by other manufacturers.

Processes that generate fine dusts such as a flour mills, wood processing plants, animal feed compounders, sugar processing, fuel handling plants are typical applications for the Ex-Go-Vent explosion relief panels.
