Abstract

The scraper is for use in a heat exchanger with an annular space defined between inner and outer tubes. It consists of a blade which is supported by one of the tubes and is pressed against the other. Pressure is provided by an inflatable body which is mechanically coupled to the blade. The blade pref. acts on the exchange surface formed by the outer tube, the inflatable body being housed in the inner tube. The latter pref. includes a radial hole through which projects a rod to transfer movement of the inflatable body wall to the blade.
