Definitions

  • Air dosing system for secondary air in coke ovens depending on the ratio of vault to bottom temperature
  • the invention relates to a device for controlling the amount of secondary combustion air in the coke oven furnace of a coke oven battery type "heat recovery” or “non-recovery", said device controls the amount of air through a cuboid essay or a plate over a servomotor is driven, so that the device can be controlled, for example via a control mechanism that depends on readings in the coke oven. In this way, the heating of the coke cake of a coke oven battery can be made considerably more uniform and improved by the secondary cooktop located under the coke oven.
  • the amount of secondary air can be supplied by the device according to the invention, if necessary in several quantity gradations. By a multiple-stage supply of secondary air, the amount of nitrogen oxides formed can be significantly reduced.
  • the invention also relates to a method for metering secondary combustion air in a coke oven.
  • the heating of Kokshuntöfen is carried out according to the prior art so that the heating of the coke cake is made as uniform as possible from all sides and the quality of the coke obtained is improved in this way.
  • the preheated coking chamber of the coking oven is filled with a layer of coal and then closed.
  • the carbon layer may be in bulk or in compacted, milled form.
  • the volatiles of the coal degas, especially hydrocarbons and hydrogen.
  • Further heat generation in the coking chamber of "non-recovery" coking ovens and "heat-recovery” coking ovens occurs exclusively through combustion of the released volatiles, which gradually outgas due to progressive warming.
  • the combustion is controlled so that a part of the released gas, which is also referred to as raw gas, is burned in the coking chamber directly above the coal charge.
  • the necessary combustion air is sucked in through openings in the doors or in the ceiling or through openings in the doors and in the ceiling.
  • This combustion stage is also referred to as the first air stage or primary air stage.
  • the primary air stage usually does not result in complete combustion.
  • the at the Combustion of heat released heats the carbon layer, forming an ash layer on its surface after a short time. This ash layer ensures an air seal and prevents the carbon layer from burning off in the further course of the coking process. Part of the heat released during combustion is primarily transferred by radiation into the carbon layer. However, a mere heating of the carbon layer from above using only a single air stage would lead to uneconomically high cooking times.
  • the partially eliminated in the primary air stage raw gas is burned in a further stage and the resulting heat is supplied to the carbon layer from below or sideways.
  • This referred to as secondary combustion subsequent combustion usually takes place in so-called Sekundäreuer commission, which are located below the coke oven chamber and below the coke cake, so that the partially burned coking gas completely burns there and the resulting heat of combustion heats the coke cake from below.

  • the leadership of the partially burned coking gas is usually taken over by so-called "downcomer" channels, which are located for example in the lateral masonry of a coke oven.
  • the air required for the secondary combustion is supplied in this procedure by so-called secondary air openings, which are located in a typical construction below the side Koksofenschen the coke oven. From there, the secondary air enters a so-called secondary air base, where the air is collected and directed into a secondary heating chamber above it. There the secondary combustion takes place.
  • the incoming combustion air is usually supplied in significantly more than stoichiometric amount. This ensures that the partially burned coking gas burns completely, so that the heat of combustion contained therein is completely discharged. In this way, the release of incompletely burned coking products, such as hydrocarbons, should be prevented.
  • the secondary air supplied usually has the temperature of the surrounding atmosphere and thus reduces the temperature of the secondary air sole and the Sekundäreuerraumes below the coke cake quite considerably. Due to the uncontrolled supply of secondary combustion air into the secondary heating space, the temperature of the secondary heating space can not be controlled, so that Sometimes the temperature of the Sekundäreuerraumes significantly different from the temperature in the Primärsortraum, also referred to as Koksofengewölbe differs. As a result, the heating of the coke from the different sides is uneven. In addition, the amount of secondary air supplied can not be regulated as a function of the amount of oxygen in the secondary heating room. This can lead to the formation of pollutants, but especially to the formation of unburned hydrocarbons or nitrogen oxides of the NO x type.
