摘要： In a process for recycling fine-particle solids (4) discharged from a reactor vessel (1) at a discharging position of the reactor vessel (1) by means of a gas, at a recycling position (16) of the reactor vessel (1), the solids (4) are separated in a solids separator (3) and subsequently collected in a collecting vessel (8) and from the same are recycled into the reactor vessel (1) by means of a conveying gas. To enhance the operation of the solids separator (3), but without causing an additional load on the reactor vessel (1), an additional gas stream (23) independent of the gas stream in the reactor vessel is conducted through the solids separator (3) in a circuit, in the direction of flow of the solids (4).

摘要： According to a process for producing pig iron (10) from fine-particulate iron oxide carriers and lumpy iron-containing material in a meltdown gasifying zone (9) of a melter gasifier (3), the iron-containing material is melted in a bed (13) formed of solid carbon carriers, under the supply of carbon-containing material and oxygen-containing gas while simultaneously forming a reducing gas. Fine-particulate iron-oxide carriers, such as iron-containing fine ore and ore dust and oxidic iron fine dust, are introduced into a reducing gas stream leaving the melter gasifier (3), and the reducing gas is separated from the fine-particulate material formed thereby. The separated fine-particulate material is introduced into the meltdown gasifying zone (9) via a dust recirculation line (26, 27, 28, 29) and through a dust burner (30), and the reducing gas is used for reducing iron-oxide-containing material. To be able to charge large amounts of fine ore or ore dust in this process, the separated fine-particulate material in the dust recirculation line (26 to 29) is conveyed via a fluidized bed sluice (25) formed by the separated fine-particulate material and by reducing gas to the dust burner (30) and reduced thereby (FIG. 1).

摘要： An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in the tubular zone. Thus within an outlet connection (2) forming the tubular zone is provided an anular insert (3), which forms a gap (4) with the outlet connection. A cooling gas is blown into this gap counter to the flow direction of the product gas. At the end of the insert, this cooling gas is deflected by the product gas and flows within the insert in the same direction as the product gas and protects the inner wall of the insert from the latter. This product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet-side end of the insert.

摘要： A combustion chamber in a melter gasifier extends into a fluidized bed to isolate fine particulate ore introduced into the chamber from the remaining internal portion of the melter gasifier. The fine particulate ore is melted in the chamber and falls on the bed to be reduced as it trickles down to the molten metal in the melter gasifler bottom. Reducing gases withdrawn from the melter gasifier are filtered through the bed, thereby preventing the fine particulate ore from being withdrawn with the gases. The chamber can be liquid cooled and use a burner to provide combustion temperatures.

摘要： A process and an arrangement for the production of molten pig iron or steel pre-products from particulate ferrous material as well as for the production of reducing gas in a meltdown gasifier. A fluidized bed of coke particles is formed by the addition of coal and the injection of oxygen-containing gas. In order to ensure a satisfactory mode of operation of the meltdown gasifier even if coal of inferior quality with a high moisture content and a high portion of volatile matter is used, additional heat is supplied to the meltdown gasifier above the feed lines for the fluidized-bed-forming oxygen-containing gas by burning and/or degassing coal particles separated from the reducing gas.

摘要： A process for continuous conveying of a fine-grained and/or pulverized solid to two or more target points by a conveying medium, e.g. gas. The solid is charged into a distribution vessel and from there to several target points by respective supply lines each at a desired target flow rate intended for target point. The target flow rate for each target point is divided into at least two partial target flow rates from the distribution vessel via separate partial supply lines. The partial target flow rates are reunited at the respective target points at the latest. To adjust the target flow rate at a target point at a specific level, individual partial supply lines leading to this target point are alternatively kept shut-off or open.
