Abstract
An arrangement for the protection of tube sections of platen-like heat-transfer surfaces disposed in a gas conduit against wear by gases laden with solid particles. A wear-protection element can be withdrawn from the gas conduit, in the direction of the lengthwise direction thereof, without the need to first loosen a fixed connection to the tube sections that are to be protected. The wear-protection element can be in the form of a rotatable deflector that protects the rounded end portions of tubes, or can be in the form of a solid section that protects linear tube sections.
