Deflagration Venting for Combustible Dusts - What You Need to Know

AIChE Webinar
Originally delivered Jan 26, 2011

Deflagration venting is one of six possible explosion protection options for combustible dust handling equipment in NFPA 654. To use this option, you must reference back to NFPA 68 where the requirements for sizing vents are located. Understanding and following these requirements can be quite complicated. Determining what data to use for KSt, Pred, etc., which equations should be applied, and how vent ducts should be designed is not always straightforward. This webinar will walk you through the key issues and pieces of information required to properly design a deflagration vent for your combustible dust handling equipment. We will explain where to find the input data, how to apply the sizing equations contained in NFPA 68 and discuss vent duct considerations.

This webinar will be helpful for anyone with combustible dust handling equipment that chooses to utilize deflagration venting as the basis of safety for protecting their equipment. Whether you plan to do the sizing yourself or contract it out, this webinar will help you understand the process, the necessary information required to conduct the evaluation, and some key issues to watch for when you get your results.
