Explosion Suppression

Chemical explosion suppression system is designed to provide an active method to protect process system equipment from a dust or gas explosion hazard. The fundamental operation of the system is detection of the pressure rise during the initial stage of an explosion, followed by fast injection and homogeneous distribution of an extinguishing agent into the protected vessel. The chemical suppression system consists of a controller, pressure or optical detectors, and the high rate discharge (HRD) bottles. As a deflagration develops, the pressure inside the vessel will begin to build rapidly. The pressure detector will detect the rate of pressure rise over a certain time period and activate the High Rate Discharge bottles. Once activated, the HRD bottles will disperse suppressant into the protected vessel inhibiting the explosion from further developing, thus reducing the pressure and preventing any vessel breach.
