ABSTRACT:
A permanently fireproof flame guard includes a flow area (2) which terminates a conduit and within which an inserted flame shield is disposed. The flame shield is provided with a plurality of passage gaps that ensure permanent fire safety. Cooling of the permanently fireproof flame guard can be improved by forming at least one concentric, annular section (5) within the flow area (2) in a massive manner without passage gaps while forming annular sections (4) comprising passage gaps around the concentric, annular section (5).
