    摘要： Procede et appareil a recipient rotatif comprenant un dispositif de raclage tournant ou alternatif, par exemple un melangeur a tambour ou un dispositif pour l'agglomeration de substances. Ledit dispositif de raclage (6, 7) forme des ondes periodiques de raclage (8) dans la couche de particules (3) sur la surface du tambour agglomerateur (1). Le dispositif de raclage est frequemment sujet a des influences perturbatrices et peut entrer en violentes vibrations qui entrainent la formation d'ondes de vibration entretenues superposees aux ondes periodiques de raclage (8). Lesdits effets perturbateurs peuvent etre elimines par destruction des ondes de vibration entretenues ou simultanement de l'onde de vibration entretenue et de l'onde periodique de raclage (8). Une disposition particulierement avantageuse consiste a changer la vitesse du dispositif de raclage (6, 7) dans un appareil du type mentionne ci-dessus de maniere que les intervalles de raclage soient suffisamment courts pour eviter le developpement d'ondes de vibrations entretenues superposees aux ondes periodiques de raclage (8).

    摘要： Method of cleaning a furnace heat exchanger and/or a flue gas heat exchanger in a boiler of an incinerator, the heat exchanger comprising bundles of tubes or a membrane wall formed by or containing tubes, the method comprising the steps of attaching a pyrotechical charge to the end of a lance, inserting the charge into the incinerator, positioning the pyrotechical charge in an ally between bundles or between the tubes in a bundle, and initiating deflagration thus removing deposits, such as slag, from the tubes.

    摘要： Provided is a method for cleaning the inside of a pressure tight container for a blasting treatment, wherein the inside of a pressure tight container can be cleaned for a short period of time after a blasting treatment. The method is comprised of a setting process wherein a cleaning blast (1) capable of cracking a part of a residual substance remaining on the inside of a pressure tight container (10), and a solid separating material (2) which collides with a substance bonded to an inner wall surface (32a) of the pressure tight container (10), to separate the bonded substance from the inner wall surface (32a) of the pressure tight container (10), are set on the inside of the pressure tight container (10); and a separation process wherein the cleaning blast (1) blasts on the inside of the pressure tight container (10), to crack a part of the residual substance remaining on the inside of the pressure tight container (10), and the separating material (2) is divided into a plurality of granular elements by the blast, so that the granular elements are spread, and collide with the bonded substance to remove the bonded substance.

    摘要： A method of removing a blockage in a solids injection lance under normal operating conditions of a direct smelting vessel is disclosed. The direct smelting vessel contains a bath of molten metal and slag and the solids injection lance extends into the direct smelting vessel and has an outlet end that is submerged in the molten slag. The solids injection lance further has a single inlet coupled to a section of supply line that conveys gas and solid feed material to the solids injection lance. The method comprises (a) advancing a blockage-removing tool through the supply line section and through the solids injection lance to an upstream side of the blockage, (b) operating the tool under elevated gas pressure conditions to remove the blockage such that solid feed material and gas are able to flow through the solids injection lance. The method further comprises (c) retracting the tool from the solids injection lance and the supply line section. Also disclosed is an apparatus for removing a blockage in a solids injection lance extending into a direct smelting vessel.
