  • Patent number: 8834153
    Abstract: In a flame arrester arrangement having a housing (1) for holding at least two flame arrester inserts (6, 6?) having a large number of axial passage gaps dimensioned for a combustible gas, and having an intermediate layer (7) arranged between two flame arrester inserts (6, 6?), which permits a radial distribution of the gas flow emerging from one flame arrester insert (6, 6?) and entering an adjacent downstream flame arrester insert (6, 6?), the ability of the flame arrester inserts (6, 6?) to be easily assembled and disassembled for servicing purposes without restricting the functional integrity can be achieved by at least one separate closed seal (11, 11?, 15, 17, 17?, 20) being arranged between a flame arrester insert (6, 6?) and the housing (1) or between two flame arrester inserts (6, 6?) in such a way that a flow around the flame arrester insert (6, 6?) in a space (12) located radially outside the passage gaps is prevented.
