The six requirements for a dust explosion
Explosion venting is one of the most common and effective forms of explosion protection. Relieving the overpressure from a potential industrial explosion and providing a planned pathway for the expanding gases to escape.
WHAT IS A DUST EXPLOSION ?
It begins with the ignition of a fuel which burns instantaneously
An explosion produces and release a large cloud of gas or dust
An explosion does not require a flame
A vessel can bursts from increased internal pressure, and then it´s called an explosion
WHAT IS AN EXPLOSION VENTING ?
A designed weak point in a pressure system
Limit the explosion overpressure by releasing unburned mixture and products of combustion
Panels do not prevent an explosion they prevent the vessel from over pressure by allowing us to control the maximum pressure
Definition : A non-reclosing pressure relief device to discharge outside the explosion energy
Designed to fail at a pre-determined pressure
