Abstract
An apparatus and method for the protection of a pipe containing an inflammable gas against back fire. The apparatus comprises a container partially filled with liquid extending along a given length of the container and at a give level, at least one gas feed pipe, and at least one horizontal inlet pipe, each immersed in the liquid and sealed at one end and receptive of gas at the other end from the feed pipe. Each inlet pipe has holes in its circumferential surface for the introduction of the gas into the liquid, with the number of holes and the dimensions thereof such that at the maximum gas volume flow rate, the outflow rate through the holes is at the most 40 m/sec and the rate in each gas feed pipe is at the most 20/sec. Additionally, each inlet pipe extends over only part of the length of the liquid in the container. A gas outlet nozzle is positioned above that part of the container where there is no pipe and a calming grid is disposed at the liquid level to subdue waves in the liquid.
