    摘要： The invention relates to a process and plant for producing sulphuric acid by catalytic oxidation of SO2 to form SO3 in a converter with at least one contact stage, the SO3-containing process gas, after it has passed through at least one contact stage, being withdrawn from the converter and fed to an apparatus for recovering heat, in which steam is generated from feedwater by means of the heat of the process gas, and the process gas then being fed to an absorber, in which the SO3 is absorbed in sulphuric acid. To improve the utilization of heat during the production of sulphuric acid, the feedwater is fed to the heat recovery apparatus at a higher temperature than the process gas fed to the absorber.

    摘要： The invention relates to a conveyor belt to be used in a continuously operated conveyor-type thermal treatment, i.e. sintering, of a material bed. The conveyor belt is provided with perforations in order to allow the gases that are used for heating and possibly cooling the material bed to flow through the material bed and the conveyor belt. According to the invention, the conveyor belt is made of a perforated, at least one-part element (1, 11, 21) made of a metal piece and allowing the gases to flow through, said element being mechanically connected to the preceding and successive element (1, 11, 21) in the proceeding direction (5, 15, 28) of the conveyor belt by means of a junction made in the lateral direction of said conveyor belt, and the perforations (2, 13, 14, 26, 27) are arranged in zones alternating with perforation-free element pats.

    摘要： The invention relates to a method for producing a ferroalloy containing nickel. From a fine-grained raw material containing iron and chromium and a fine-grained raw material containing nickel, a mixture is formed with binding agent, the mixture is agglomerated so that first formed objects of desired size are obtained. The objects formed are heat treated in order to strengthen the objects so that the heat treated objects withstand conveyance and loading into a smelter furnace. Further, the objects are smelted under reducing circumstances in order to achieve ferrochromenickel, a ferroalloy of a desired composition containing at least iron, chromium and nickel.

    摘要： A concentrate burner of a suspension smelting or suspension converting furnace includes a reaction gas feed, a powdery solid matter feed and a concentrate distributor. An arrangement for feeding powdery solid matter to the concentrate burner includes a first powdery solid matter discharge pipe for feeding powdery solid matter into the powdery solid matter feed of the concentrate burner. The first powdery solid matter discharge pipe is provided with a first partition, which divides solid matter, for dividing the first powdery solid matter discharge pipe into two essentially similar discharge pipe parts. The powdery solid matter feed of the concentrate burner comprise an annular concentrate discharge channel that surrounds the concentrate distributor of the concentrate burner. Each discharge pipe part of the first powdery solid matter discharge pipe is at least partly divided into two discharge pipe portions by a second partition.

    摘要： In a method for producing metal powder, the first part of an acid-containing starting solution is fed on the anode side of an electrolytic cell as anolyte, to contact the anode and supply material containing yield metal, and a second part of the acid-containing starting solution, which also contains intermediary metal, is fed on the cathode side of the electrolytic cell, to contact the cathode as catholyte. Yield metal is oxidized and dissolved in the anolyte by leading electric current in the anode. The yield metal contained in the second part of the starting solution is reduced on the cathode side. Anolyte solution and catholyte solution are fed to a precipitating chamber for mixing the dissolved, oxidized yield metal and the second part of the starting solution containing reduced intermediary metal.
