Management of Explosion Risks: Prevention and Protection • Can the equipment accept the reaction forces generated by the vented release? Each application requires unique assessment that • Can buildings or equipment in the free vent path includes the following considerations: accept the shock loading of the explosion pressure • Quantify the risk; define the deflagration pulse and accept the momentary high temperature characteristics for the process material (testing may of the fireball? be required) • Consider whether a hybrid of prevention and Answers to these questions will often determine that...

Successful management of deflagration risks requires • If there are process inlets and outlets to the that the characteristics of the material (such as Pmax protected equipment, are these protected to prevent and Kst - the deflagration index of a dust) are known propagation of the de­­­­ flagration to other equipment along with the process conditions, such as dust concentration, airflow velocity, operating pressure, or work areas? Codes and standards are now very clear in requiring isolation of vented equipment to temperature and humidity. prevent secondary explosions. Secondary explosion Economic...

System monitor Explosion detection unitized sensors Explosion cannon Power supply Type IPD Core Technologies The BS&B explosion suppression system detects the earliest stage of a deflagration by sensing the pressure wave that comes ahead of the flameball and uses this signal to activate delivery of an extinguishing agent into the developing flameball to suppress it before reaching destructive proportions.  A typical system consists of a sensor, power supply module, system monitor and several explosion suppression "cannons".  The quantity, size and location of sensors and cannons are determined...

BS&B Flameless Venting IQR System Where the flameball ejected by a deflagration cannot be accepted and ducted relief is impractical, flameless venting technology provides an alternate passive protection system. How the IQR System Works The IQR system comprises of two parts, an explosion vent and a quenching module.  The explosion vent responds to the rapidly building pressure of a deflagration and opens to relieve this pressure.  As the developing fireball passes through the open explosion vent, it is intercepted by the quenching module.  A stainless steel precision mesh, retained by a frame,...

Spark detector sensor SDN External monitoring panel Automatic Extinguishing Device Spark Detection and Extinguishing System Spark detection and extinguishing technology is employed to manage the risk of fire and explosion ignition due to sparks and burning embers that are transported through a combustible dust handling system. By detection of near infrared energy, sparks and embers are first located and then extinguished by water spray downstream of the detection point. Operation of the system is fully automatic. Detectors located to the wall of process piping, downstream of the source of sparks...
