IRDB, DT INLINE FLAME ARRESTER

AMAL IRDB, DT Inline Flame Arrester
A bi-directional inline flame arrester used to prevent flame transmission of a detonation confined within a pipeline. With their fabricated bodies and replaceable elements we can size an IRDB specifically for your application. The IRDB range are defined as unstable detonation which occurs during the transition process from a deflagration into a stable detonation – unstable is the more severe type of detonation combustion

AMAL IRDB, DT Inline Flame Arrester
A flame arrester is a passive explosion protection device with no moving parts. At the core of each Amal flame arrester is a crimped metal element, which in section comprises a series of triangular passages or cells. All gases have a defined gap through which a flame will not pass; this is called the Maximum Experimental Safe Gap (MESG). To quench a flame, and so prevent its onward passage, the height of the cells in the element should be below the MESG of the gas/vapour being handled.
The length of the cells in the element is also important. Once the flame enters the element, the cells will absorb heat from the burning gas, progressively reducing its temperature so that when exiting the arrester, the gases are cooled to below the point where auto ignition would occur.

After more than 80 years’ of experience and extensive testing Amal has conclusive proof that the crimped metal concept of triangular cells is without doubt the most effective method of quenching potentially lethal or destructive flame fronts.
