Abstract

En hul trommel eller tørkesylinder (2) som skal roteres og oppvarmes som en følge av forbrenning av brenngass inne i tørkesylinderen, slik at banemateriale, såsom papir- eller tekstilmateriale, utsettes for tørkeoppvarming ved å komme i berøring med en ytterflate av sylinderen (2). Sylinderen (2) omfatter en sylindrisk, varmeledende vegg (4) av metall. En flatbrenner (24) for forbrenning av brenngass tilført denne (blandet med forbrenningsluft) gjennom rør (20, 22), er montert inne i sylinderen (2) og har en brennersliss (26) som vender mot og er nær en innerflate (28) av sylinderen (2). En akustisk avskjerming (64), for å absorbere lyder dannet ved forbrenningen av brenn- gassen, er montert bak brenneren (24) ved en motsatt side av rotasjonsaksen til sylinderen (2) i forhold til siden som brenneren er anbrakt på. Avskjermingen (64) som strekker seg langsgående til tørkesylinderen (22) kan omfatte porøse lag (66, 68) av keramiske fibre.A hollow drum or dryer cylinder (2) to be rotated and heated as a result of combustion of fuel gas inside the dryer cylinder, so that web material, such as paper or textile material, is subjected to drying heating by contact with an outer surface of the cylinder (2) . The cylinder (2) comprises a cylindrical, heat-conducting wall (4) of metal. A flat burner (24) for combustion of fuel gas supplied to it (mixed with combustion air) through pipes (20, 22), is mounted inside the cylinder (2) and has a burner slot (26) which faces and is close to an inner surface (28) of the cylinder (2). An acoustic shield (64), to absorb sounds formed by the combustion of the burner gas, is mounted behind the burner (24) at an opposite side of the axis of rotation of the cylinder (2) relative to the side on which the burner is placed. The shield (64) extending longitudinally to the dryer cylinder (22) may comprise porous layers (66, 68) of ceramic fibers.
