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 A wear-protection element can be withdrawn from the gas conduit, in the direction of the lengthwise direction thereof, without the need to first loosen a fixed connection to the tube sections that are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.
Claims5
An arrangement protecting tube sections of platen-like heat-transfer surfaces in a gas conduit against wear from gases laden with solid particles, comprising:
- elongated tube sections that form part of said platen-like heat-transfer surfaces;
- and
- wear protection element means having a lengthwise dimension and including, for a given elongated tube section that is to be protected, at least one wear-protection element that extends parallel to said tube section and while covering same is spaced upstream therefrom as viewed in the direction of a flow of gas through said gas conduit whereby particles are deflected through said tube sections so as to substantially avoid contact therewith, with said wear-protection element means being nonfixedly disposed in said gas conduit in such a way that it can be withdrawn therefrom, in the direction of said lengthwise dimensions thereof, with the distance of each wear-protection element from its tube section that is to be protected being less than or equal to the distance between adjacent elongated tube sections of said heat-transfer surface.
