Abstract
A flame arresting method, conduit section and apparatus for the safe disposal of combustible waste gases from a source such as a reactor. The invention involves providing a waste gas conduit section with a flame-detecting chamber and one or more upstream snuffing chambers divided by flame arresting grid members, and automatically introducing snuffing gases to the snuffing chamber(s) whenever a flame is detected in the flame-detecting chamber. The outlet from the waste gas conduit section opens to a combustion chamber, for incineration purposes, or to a scrubber.
