An explosion of flammable dust poses a serious hazard to a wide range of industries including manufacturing, processing, metalworking, chemical, and many more. This hazard can occur in many areas of the plant but is more likely to occur in dust collection systems. Implementing suitable explosive ventilation in your dust collection system can reduce the risk of a hazardous explosion.
The first step is to identify and determine if there is a risk of flammable dust in your facility. If you find your facility at risk, it is important to consider your options for prevention and protection. You can also learn more about explosion prevention equipment via coopatex.co.uk/.
Explosion Venting Strategies:
Preventive Maintenance Plan: In conjunction with the protection strategy, each facility must implement a well-designed and managed preventive maintenance plan. A preventive maintenance schedule for your dust collection system will help you control the level of combustible dust.
Explosion Vent or Panels: Vents or panels are designed to burst at the set pressure (PSat). The explosion vent provides a relief avenue for the expanding gasses, but the pressure in the vessel will continue to rise until it reaches the Pred pressure.
This is the maximum pressure of the ignition event when explosion vents are functioning, so this is usually the pressure rating the vessel is designed to withstand.
Explosive panels can be used with short duct lengths to allow for indoor use without flameless venting. Although these vents require replacement once a rupture occurs, they are simple and inexpensive.
