ABSTRACT:
In the method of operating heat exchangers by means of hot gas streams containing condensable components, the hot gas stream (1) is divided into substreams (4) and cooled by means of obstacles (3) having a temperature T which is small in comparison with the entry temperature T.sub.I of the hot gas stream (1), in particular less than the dew point temperature T.sub.D of the hot gas stream (1). The substreams (4) are, after leaving the obstacles (3), combined with one another and, in their cores (8), divided into other substreams (6) and cooled by means of further obstacles (3) at the temperature T. This procedure is repeated until the hot gas stream (7) leaving the heat exchanger (2) reaches an exit temperature T.sub.O of from 200.degree. C. to 60.degree. C., preferably from 120.degree. C. to 80.degree. C.
