Abstract

A self-cleaning heat exchanger 10 having a set of tubes 14 extending between two headers 12, 16 comprises means 20 for introducing tube scouring projectiles 18 into a first of the headers and a filter 22 for separating the projectiles from the fluid after passing through the tubes into the second header. In the invention, means 30 are provided for accelerating the fluid flow through some of the tubes 14 of the heat exchanger in order to assist in dislodging projectiles that come to a standstill on encountering excessive resistance while passing through a tube. During a blockage clearing cycle, different sets of tubes are cleared sequentially until all the tubes have been cleared.
