Dust Explosion protection technology is an important application in pneumatic conveying industries. It is a vital business for equipment manufacturers and an important issue for users of dust handling machineries. Recent development in Europe demands all dust handling equipment to be regulated under European commission directive called ATEX 100 (Directive 94/9-ATEX) in which all machineries must be inspected and approved for usage in EU member countries by competent laboratories. Equipment manufacturer of pneumatic conveying system, Gericke Pte Ltd, is interested to certify their filtration apparatus under the CE scheme. The report will explore how the European pressure vessel code would be used as a design standard for explosion proof equipments. The author demonstrates the soundness of the current design using design by formula approach taken from CENELEC pressure vessel code EN 13445. The report also explored certain design concepts recommended by industry experts for a holistic approach to explosion proof design. As a result of these studies, the author recommends a set of changes that would improve any weakness in structural design. Finally, the finite element approach is used to estimate the behavior of the structure under overpeak pressure influence and ultimately allow the designer to verify its design.
