Explosion Suppression & Flame Arrestors

Explosion Suppression and Flame Arrestors. Explosion and flame are related hazards with different protection methods. A flame arrester is a device installed in a process to stop the propagation of a flame traveling along a pipeline by extinguishing the it. They are used on storage tank vents and gas pipelines. Flame arresters force a flame front through channels too narrow to permit the continuance of a flame. An explosion suppression system consists of an explosion detector, control system, and suppressor unit. The suppressor unit stores the suppressant under pressure for release at high speed. A good suppressant should have the following properties: quenching ability - rapid heat absorption from the combustion zone by energy transfer; dilution - suppressant concentration should dilute the inburned mixture a point where it is non-flammable; wetting - unburnt dust particles are rendered non-flammable by absorption of liquid suppressant; chemical action - chemical composition of the suppressant directly interferes with combustion.
