摘要： A TSL lance has an outer shell of three substantially concentric lance pipes, at least one further lance pipe concentrically within the shell, and an annular end wall at an outlet end of the lance which joins ends of outermost and innermost lance pipes of the shell at an outlet end of the lance and is spaced from an outlet end of the intermediate lance pipe of the shell. Coolant fluid is able to be circulated through the shell, by flow to and away from the outlet end. The spacing between the end wall and the outlet end of the intermediate pipe provides a constriction to the flow of coolant fluid to increase coolant fluid flow velocity therebetween. The further lance pipe defines a central bore and is spaced from the innermost lance pipe of the shell to define an annular passage, whereby materials passing along the bore and the passage mix adjacent to the outlet end of the lance. The end wall and an adjacent minor part of the length of the shell comprise a replaceable lance tip assembly.

摘要： A heat exchanger for use in a contact group of a sulfuric acid plant includes a chamber in which a tube bundle is arranged on a circular ring. A gas space is formed between the tube bundle and a chamber casing surrounding the tube bundle. A gas supply opening is provided in the chamber casing and is configured to introduce a gas into the gas space substantially radially to the tube bundle. A gas outlet opening adjoins an interior space enclosed by the tube bundle in a substantially axial direction. A center of the tube bundle is offset with respect to a center of the chamber casing in a direction opposite to the gas supply opening.

摘要： A process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step and a second roasting step. A gas mixture is formed from the first process gas component obtained from the first roasting step and from the second process gas component obtained from the second roasting step. Post combustion of the gas mixture is made in a post combustion chamber that uses the sulphide rich first process gas component and the second process gas component as oxidizer gas in order to decompose SO3 in the gas mixture. The exit gas is exposed to subsequent gas cooling and dust removal steps.

摘要： A method for providing a suspension smelting furnace with constant and continuous feed is disclosed. The method employs intermediate storage bins for fine-grained feed, a feed rate controller for accurately controlling the feed rate of the fine-grained material, and a pneumatic conveyor for lifting the feed up to the top level of the suspension smelting furnace where the burner of the furnace is adapted. The heavy constructions of the storage bins are located close to the ground level and the constructions around and on top of the furnace have been designed essentially lighter than in conventional solutions.

摘要： An X-ray tube includes a cathode, an anode with an electron receiving surface, and a window facing the electron receiving surface of the anode. On the electron receiving surface of the anode it includes a layer of anode material. Deeper in the anode than the layer of anode material, there is a block of attenuator material. The atomic number of the attenuator material is less than one third of the atomic number of the anode material.
