Abstract

The invention relates to a method of removing dust deposits from heat-exchange surfaces where gas containing dust passes through a pipe or through a chamber (2) containing coolant tubes (3). Sound is generated in known manner from sirens (5) and particulate material (e.g. sand) is fed via a pipe (6) to mix with the gas containing the dust. The "sand" and dust are deposited on the tubes and are removed together by means of the sound generation more easily than would be the case if the "sand" were not being incorporated in the deposit. The grain size of the "sand" should be larger than that of the dust.
