  • Patent number: 9802838
    Abstract: A method and apparatus are disclosed for treating process water which is loaded with gaseous compounds and/or possibly with solids and comes from a wet-cleaning installation for cleaning process gas, e.g., from a melt-reduction subassembly or from a direct-reduction subassembly. Process water is introduced in a tank in a first process stage and degassed on the basis of reduced solubility of the dissolved compounds. The tank has, on its upper side, a gas-collecting chamber, in which the separated-off gases are collected and from which these are discharged. Likewise, the treated process water is discharged from the tank via a drainage means.

  • Patent number: 9470456
    Abstract: A melter gasifier of a smelting reduction installation is charged by bringing together coal -containing material in lump form and iron carrier material (which may be hot) before and/or while they enter the melter gasifier. The ratio of the combined amounts of iron carrier material and coal-containing material in lump form is variable. The combined amounts of iron carrier material and coal-containing material in lump form are distributed over the cross section of the melter gasifier by a dynamic distributing device, and the ratio of the combined amounts of the iron carrier material and coal-containing material in lump form is set depending on the position of the dynamic distributing device.

  • Patent number: 9139884
    Abstract: A process and an apparatus for producing liquid pig iron or liquid primary steel products from charge materials formed by iron ores and additions. The charge materials are subjected to a further reduction in a reducing zone (1) and are then fed to a smelting zone or a smelting unit (2), in particular a fusion gasifier, for smelting with the addition of carbon carriers and oxygen-containing gas to form a fixed bed. A CO- and H2-containing reduction gas is formed, which gas is introduced into the reducing zone converted there and drawn off as top gas. The hot top gas, laden with solid matter, after separation of the solids, is subjected at least to a dry coarse separation and at least parts of the hot solids segregated by the separation are returned into the smelting zone or the smelting unit (2) or the reducing unit (1). In addition, the top gas is treated in a further fine separation stage (13A).

  • Publication number: 20150136046
    Abstract: A method and a system for generating steam using the waste gases from plants for pig iron manufacture: waste gas removed as export gas (12) from the plant for pig iron manufacture is thermally utilized by combustion, and the waste gas from the combustion is fed to a heat-recovery steam generator (29). To utilize more energy from the export gas (12) for power generation, the export gas (12) is fed into a combustion chamber (23) located upstream of the heat-recovery steam generator (29), and after the combustion in the heat-recovery steam generator (29), heat is extracted from the export gas (12) without the export gas (12) passing through a gas turbine between combustion and heat-recovery steam generator. The pressure in the combustion chamber (23) and heat-recovery steam generator (29) are set above atmospheric pressure by means of a gas flow regulator (31) that is located downstream of the heat-recovery steam generator (29).

  • Patent number: 8540931
    Abstract: An injector insert pipe is arranged in the gas channel of a nozzle for injecting oxygen-containing gas into a pig iron production unit, wherein an interspace which surrounds the pipe is present over the entire pipe length between the wall of the gas channel and the pipe outer wall. The pipe extends at least as far as the nozzle end face which contains the mouth of the gas channel. The pipe space is connected to an oxygen-containing gas feed line, and the interspace is connected to a protective gas supply line. In a process, oxygen-containing gas is fed into the pipe space, which after it has flowed through the pipe, enters the production unit at an entry velocity, and the interspace is simultaneously flowed through by a gas which exits into the production unit at an exit velocity, wherein the entry velocity is greater than the exit velocity.
