Explosion Venting/Suppression Q&A
-
Is there any chance of explosion in vacuum tray dryers? What are some safety measures required to prevent this?Answered May 2nd, 2011 by Expert:The short answer is, “Yes there is a chance” and it is difficult to quantify. NFPA specifically mentions dryers, including vacuum tray dryers, “should be designed, constructed, installed and monitored so that the required conditions of safety for operation of the air heater, the dryer, and the ventilation equipment are maintained.” NFPA 654 A.7.18.
With respect to dryers, there is a risk of accumulated dust on the dryer or in the dryer and there is always the risk of a spark igniting a dust cloud. Safety measures to be taken are the standard: provide effective venting and isolation systems to minimize the impact of the explosion and prevent the explosion from traveling to other parts of the process.
