Abstract

The waste gas pipe (3) is positioned in the chimney shaft forming the air-feed duct (2), a little apart from the shaft wall. The outer periphery of the waste gas pipe has ridges (7), parallel with the pipe's longitudinal axis. The ridges may be lateral to the pipe's longitudinal axis. The cross-sections of the ridges is triangular or rectangular, with rounded free edges.
