Definitions

  • the invention relates to a method for the afterburning of exhaust gases containing carbon monoxide from metallurgical processes with discontinuous exhaust gas volumes, the composition and / or quantity of which changes during a period within which exhaust gas is produced.
  • Such metallurgical processes can be, for example, secondary metallurgical processes in which a molten metal is degassed or decarburized.
  • Flare gases In petrochemical and metallurgical processes it is generally known to burn exhaust gases with so-called flares. Flare gases often have different qualities. To ensure that the torch burns steadily, the gas must have a minimum combustible content. If this is not the case, natural gas may be added as fuel gas. Calorimeters are usually used to determine the calorific value of the flare gas. These include a measuring cell in which a measuring gas is burned. If the sample gas is successfully ignited, the amount of energy released during combustion or the calorific value of the gas is determined and, if necessary, natural gas is mixed into the flare gas.
  • carbon-containing material is fed to a melt pool of metal and slag in a direct melting vessel, with hot gas from furnaces being fed into a gas space is supplied above the melt bath for the purpose of afterburning the reaction gases of the melt bath.
  • the resulting exhaust gas is used with fuel gas and oxygen-containing combustion air to heat the ovens, whereby the temperature of the gas space in the ovens is regulated by supplying the exhaust gas with fuel gas and combustion air depending on the oxygen content in the exhaust gas of the ovens, if the exhaust gas has a certain calorific value falls below.
  • a method according to the preamble of claim 1 is, for example, from US 5,980,606 A known. Further state of the art is from the documents US 2019/242575 A1 and US 6,042,633 A known.
  • the invention is therefore based on the object of providing a method for the afterburning of carbon monoxide-containing exhaust gases from metallurgical processes with discontinuous exhaust gas volumes and exhaust gas compositions, which enables safe afterburning of the exhaust gas with a lower environmental impact.
  • One aspect of the invention relates to a method for the afterburning of carbon monoxide-containing exhaust gases from metallurgical processes with discontinuously occurring exhaust gas volumes, the composition of which changes during a period within which exhaust gas is produced, the method comprising conditioning the exhaust gas before the afterburning, such that At least one fuel gas and / or another additional gas is added in a controlled manner to the exhaust gas upstream of the afterburning, the regulation taking place depending on the composition of the exhaust gas and / or depending on the exhaust gas volume flow.
  • the afterburning of the exhaust gas preferably takes place with an open flame in the area of the mouth of an exhaust gas duct into the atmosphere.
  • the afterburning of the exhaust gas can take place in a combustion chamber provided for this purpose.
  • the invention can be summarized in that, according to the invention, both the calorific value of the exhaust gas and the exhaust gas volume flow are regulated, so that on the one hand the most complete combustion possible is ensured and, on the other hand, it is ensured that the exhaust gas volume flow is adjusted in such a way that a flow velocity of the exhaust gas in the relevant Cross section sets that is smaller than a flame propagation speed of the exhaust gas, so that re-ignition of the exhaust gas into an exhaust gas duct is excluded.
  • the exhaust gas composition and the exhaust gas volume flow are interrelated, especially if an inert gas is added as additional gas.
  • Nitrogen is expediently added to the exhaust gas as additional gas in order to increase the exhaust gas volume flow. This reduces the calorific value of the exhaust gas, which means that the amount of fuel gas supplied, for example in the form of natural gas, may have to be increased.
  • a calorific value of the exhaust gas is determined indirectly via the carbon monoxide content of the exhaust gas using at least one device for gas analysis becomes. For this purpose, results from a gas analysis that is required anyway can be used in secondary metallurgical processes.
  • control takes place depending on the carbon monoxide content of the exhaust gas, with the control goal of the greatest possible conversion of carbon monoxide to carbon dioxide, so that essentially stoichiometric afterburning is guaranteed.
  • control is carried out in such a way that the calorific value of the exhaust gas does not fall below ⁇ 2kWh/Nm 3 ( ⁇ 200 BTU/scf). It has surprisingly been found that with such a calorific value, an afterburning of carbon monoxide of over 97% is possible.
  • the control can be carried out in such a way that the exhaust gas volume flow does not fall below a given minimum volume flow.
  • the minimum volume flow of the exhaust gas is expediently determined as a function of the flow velocity of the exhaust gas in a given flow cross section so that the flow velocity is smaller than a flame propagation velocity of the exhaust gas during combustion.
  • Typical flame propagation speeds are on the order of approximately 0.2 to 0.5 m/s.
  • the afterburning is preferably carried out using at least one supporting gas torch arranged in or on a chimney.
  • fuel gas and/or additional gas or inert gas is expediently carried out via separate feed lines with volume flow controllable valves, which are controlled, for example, by means of a software controller.
  • a software controller can be implemented, for example, using a programmable logic controller.
  • the invention further relates to a method for exhaust gas aftertreatment during vacuum treatment of liquid steel in a secondary metallurgy
  • Process comprising the afterburning of the exhaust gas from the vacuum treatment of a metal melt by means of at least one torch in or on an exhaust gas duct of a vacuum pump, the method comprising conditioning of the exhaust gas before the afterburning, such that the exhaust gas upstream of the afterburning at least one fuel gas and / or a Additional gas is added in a controlled manner, the regulation taking place depending on the composition of the exhaust gas and depending on the exhaust gas volume flow.
  • the vacuum treatment of liquid steel is usually a batch process in which the exhaust gas aftertreatment according to the invention is particularly useful and expedient.
  • the exhaust gas aftertreatment according to the invention preferably takes place in secondary metallurgical processes such as VD, VD-OB, RH, RH-TOP, RH-OB, VacAOD VODC or VOD processes.
  • the afterburning is carried out periodically only during the decarburization phase of the molten metal. If the CO proportion of the exhaust gas falls below a predetermined minimum value, which is significantly below the value that would justify an increase in the calorific value with fuel gas, afterburning preferably does not take place. This is due to the fact that during the degassing of a melt, which in itself already represents a discontinuous process, exhaust gas containing carbon monoxide is only produced for a certain period of time.
  • the invention further relates to an afterburning device for afterburning exhaust gas during a vacuum treatment of liquid steel in a secondary metallurgical process, comprising at least one torch on an exhaust of an exhaust duct of a vacuum pump of a secondary metallurgical system, means for supplying fuel gas to the torch, and means for feeding an inert gas in the exhaust duct of the vacuum pump upstream of the flare, means for determining the exhaust gas volume flow and/or for measuring the exhaust gas velocity within the exhaust duct, means for analyzing the exhaust gas composition, means for metering the fuel gas and the inert gas and means for Control of the dosage of the fuel gas and/or the inert gas depending on the exhaust gas composition.
  • Volume flow controllable valves can be provided as means for metering the fuel gas and the inert gas, which are each arranged in feed lines for fuel gas and for natural gas, which are connected to the exhaust gas duct.
  • At least one control device is provided as a means for metering fuel gas and/or inert gas, the input variables of which are the exhaust gas composition, the exhaust gas volume flow, the amount of fuel gas supplied and the amount of inert gas supplied.
  • control device comprises at least one programmable logic controller.
  • control device can control a support burner of the torch in such a way that the torch is only operated when exhaust gas containing CO is produced.
  • afterburning device 1 which comprises a torch 2 with a support burner 3, which is connected to the exhaust 4 of an exhaust duct 5 of a vacuum pump, not shown, of a metallurgical plant.
  • the metallurgical system can, for example, include a casting ladle and devices for degassing the molten metal contained in the casting ladle.
  • the degassing of the metal melt can be carried out, for example, using a partial degassing process, such as the Ruhrstahl-Heraeus process, in which a vacuum vessel is immersed in the melt for degassing, with vacuum pumps designed as steam jet pumps generating a negative pressure in the vacuum vessel for degassing the melt becomes.
