摘要：

Numerical analysis of the burning-through of porous flame arresters was performed. It was shown that the burning-through time for porous flame-arrester elements of the channel type is determined by the time of flame entry into the porous element, and for granular-type elements, it is determined by the propagation time in the element. The fire resistance of a channel flame arrester increases with increasing thermal conductivity of the material of the porous flame-arrester element and its length and with decreasing effective size of the channels and porosity of the flame-arrester element. It is established that, by increasing the length of the porous element or by decreasing the channel diameter and porosity, it is possible to ensure that the flame that arises behind the flame arrester is stabilized on the exit surface of the flame-arrester element without penetrating into it.
