Definitions

  • the present invention relates to a shaft furnace, in particular a cupola furnace and a method for operating the same.
  • a cupola is a shaft furnace in which metals are melted.
  • Cupola furnaces are used for the production of cast iron. This is a set of iron, which consists mostly of pig iron, cast iron, steel scrap and other ferroalloys, melted. Foundry coke is generally used as the fuel in the cupola furnace, which is burned by reaction with oxygen, thereby releasing the amount of energy necessary to melt the iron charge.
  • a shaft furnace in particular a cupola disclosed.
  • This cupola has at least one supply line for a pumped medium, at the downstream end of a drive nozzle is connected.
  • a residual draft line for supplying a residual wind is provided in the shaft furnace.
  • a shaft furnace in particular a cupola, emerges to melt a feedstock.
  • This cupola comprises a supply line for an oxygen-containing injection gas, at the downstream end of which a motive nozzle is connected.
  • a Injektorwind réelle is provided which opens into the supply line for the oxygen-containing gas or in the drive nozzle.
  • the shaft furnace to a burner which is connected to a supply line for a gaseous oxidizing agent and a supply line for a liquid or gaseous fuel.
  • the object of the present invention is to provide a shaft furnace and a method for operating a shaft furnace, in which the consumption of fossil fuel, in particular of foundry coke, is reduced.
  • a shaft furnace for melting a metal-containing insert with at least one nozzle device.
  • the nozzle device comprises an exhaust nozzle for exhausting a residual wind connected at its downstream end to a residual draft pipe, and a driving nozzle for supplying an oxygen-containing conveying medium connected at its downstream end to a delivery medium pipe.
  • a Injektorwind effet connected to the conveying medium line or the driving nozzle is provided.
  • An exit end of the motive nozzle is provided with an injector lance, and the injector lance is disposed in the motive nozzle such that the exit nozzle concentrically surrounds the motive nozzle.
  • the motive nozzle is designed in such a way that the delivery medium is accelerated in the motive nozzle and an injector wind is sucked in by means of the negative pressure arising during acceleration of the delivery medium and combined with the delivery medium to form a motive nozzle stream, and the motive jet stream and a residual wind are conducted into the shaft furnace.
  • the nozzle device comprises at least one fuel lance, which is an integral part of the nozzle device and whose downstream end is connected to a fuel line.
  • the nozzle device is designed such that the motive nozzle stream entrains fuel, so that the motive nozzle stream is mixed with the residual wind and with the fuel and the resulting motive nozzle stream is injected via the nozzle device into the shaft furnace.
  • shaft furnace is used e.g. a cupola understood, in particular a cupola for melting gray cast iron or cast iron. But other shaft furnace systems for melting of other metallic inserts, such. As copper or for melting non-metallic materials, for example for the production of mineral oil wool, can be operated according to the invention.
  • feedstock is intended to include metal-containing and non-metallic charges that are fed to a shaft furnace for melting.
  • this includes in particular the so-called iron or cold set, consisting of pig iron, cast iron, steel scrap and / or other ferrous additives.
  • iron or cold set consisting of pig iron, cast iron, steel scrap and / or other ferrous additives.
  • copper-containing or non-metallic batches are conceivable as an insert.
  • wind, residual wind and injector wind are understood to mean the oxygen-containing gas streams supplied to the shaft furnace, in particular hot and / or air streams supplied under elevated pressure.
  • conveying medium is preferably understood to mean an oxygen-containing gas stream having an oxygen content of more than 90%, or more than 95%, and preferably more than 99%. However, it is also conceivable to use oxygen-enriched air as the conveying medium.
  • the oxygen content of the motive jet stream resulting from the combination of the conveying medium and injector wind is particularly preferably between 25% by volume and 65% by volume and between 30% by volume and 55% by volume and in particular between 35% by volume and 45% by volume.
  • the oxygen content of the motive nozzle stream can be used to control the combustion of the fossil fuel. For example, by increasing the oxygen content of the motive nozzle stream, the combustion of both the foundry coke and the fuel supplied via the fuel lance can be intensified, thereby increasing the temperature of the combustion gases and burning more fossil fuel per unit time.
  • the nozzle device has at least one fuel lance which is an integral part of the nozzle device and whose downstream end is connected to a fuel line.

In this way, the melting performance can be optimized and the amount of foundry coke can be significantly reduced. This reduces the consumption of foundry coke by up to 30%. As a result, the costs of melting can be reduced since the future expected raw material prices of the foundry coke are higher than those of the alternative fuel to be supplied via the fuel lance.
  • the advantages described above can not be achieved because the burner can bring energy only in the edge region of the furnace.
