Patent ID: 6978845

Claim:
Flame barrier arrangement ( 1 ), having at least two flame barrier elements ( 2 ) which are arranged one behind the other in a direction flow of a combustible gas and have a multiplicity of gaps for extinguishing a flame impinging on the surface of a flame barrier element ( 2 ) of said two flame barrier elements, and having at least one spacer element ( 5 ) between said two flame barrier elements ( 2 ), in order to produce a space between said two flame barrier elements ( 2 ), wherein one spacer element ( 5 ) is securely joined, at least at certain points, to the surface of a flame barrier element ( 2 ) of said two flame barrier elements, wherein the spacer element ( 5 ) is shaped in such a way that it forms bearing points which are distributed over the entire surface of the corresponding flame barrier element ( 2 ) and provides element ( 2 ) under a compressive load, wherein the bearing points of the spacer element ( 5 ) are distributed uniformly over the surface of the corresponding flame barrier element ( 2 ), and wherein the spacer element ( 5 ) is in grid form.
