Abstract

1. Heating gas flue for heating boilers for burning liquid or gaseous fuels, consisting of a water carrying wall of which the part nearest the combustion chamber is double-walled and is provided with longitudinal ribs which divide the entire cross section of the flue into individual channels, characterised in that the longitudinal ribs are constructed as U-, L- or T-profiles (1) and are arranged so that their webs (2) which extend transversely to the free legs (9) entirely cover the wall (3) nearest the combustion chamber and rest on this wall (3) and in places are welded to the wall (3) in heat-conducting manner, in such a way that the heat-conducting cross sections of the heat conductive bridges (5) thus formed decrease towards the outlet end of the heating gas flue corresponding to the outlet end of the boiler, longitudinal weld slots (16) or weld connections free from added weld material being arranged in order of decreasing length, with increasingly great spacings therebetween, on the webs (2) of the profiles (1), to form the graduatedly effective conductive bridges (5).
