Abstract

The invention relates to a tubular heat exchanger with combustion gases, e.g. the exhaust gases of a boiler plant flowing through its tubes. In order to achieve improved cleaning of the exhaust gases and, at the same time, a heat gain, the invention provides at least one tube (1) for forming an accumulation of condensate in the tube interior and having one or more dam-like projections (7) which decrease its clear through cross-section, and/or an oblique slope. <IMAGE>
