Definitions

  • the invention relates to a coke oven in flat construction, a so-called non-recovery or heat-recovery coke oven having at least one measuring device for measuring the concentration of gas components of the coke oven chamber, the coke oven sole and / or the exhaust duct and in which Based on this data, the optimum supply of primary and / or secondary air is determined and regulated via a process computer.
  • the invention comprises a coking process using such a coking oven.
  • the heating of heat-recovery furnaces is usually carried out by combustion of the gas formed during coking or of the readily volatile components of the coal to be coked.
  • the combustion is controlled so that a portion of the gas burns above the coal charge with primary air in the furnace chamber.
  • This partially combusted gas is fed via gas channels, which are also referred to as "downcomer", the sole of the furnace chamber and completely burned here by adding further combustion air, the secondary air.
  • the primary air is sucked through openings in the doors from the atmosphere.
  • the secondary air is sucked in through openings close to the floor and directed through channels into the heating cables, which run essentially horizontally under the coke oven chamber.
  • the openings for primary and secondary air are either permanently open or provided with flaps for adjusting the amount of air to be sucked.
  • the object of the invention is therefore to remedy the shortcomings described in an economical manner and to ensure an optimized supply of primary and / or secondary air to improve the furnace performance and thus shorten the cooking times.
  • a coke oven in flat construction a so-called non-recovery or heat-recovery coke oven comprising a coke oven chamber and a coke oven sole consisting of channels, the coke oven chamber and the coke oven sole are connected via gas channels, and openings for supplying primary air and one or more openings or channels for supplying secondary air into the coke oven sole are provided in the oven wall or oven door and arranged in front of the openings or in the lines to the opening shut-off devices.
  • ⁇ at least one measuring device for concentration measurement of gas constituents of the coke oven chamber, the coke oven sole and / or the gas channels arranged connected, and
  • This measuring device is in turn connected to a computer unit such that this computer unit can receive data and measurement results of the measuring device, and ⁇ the computer unit is connected via control lines with one or more adjusting devices of the shut-off devices, the shut-off valves, valves, flaps, slides or the like.
  • a temperature measuring device is arranged, which is also connected to the computer unit such that it can receive data and measurement results of the temperature measuring device.
  • the measuring devices are ideally analyzers for measuring hydrogen, nitrogen, carbon monoxide or carbon dioxide, which are connected via a line to the coke oven chamber. The concentration of these main components or one of these main components correlates very well with the cooking state of the coke cake.
  • the measuring device is a
  • Lambda probe which is arranged to determine oxygen in the coke oven sole or in the exhaust duct.
  • At least one analyzer for the determination of hydrogen, nitrogen, carbon monoxide or carbon dioxide and a lambda probe for the determination of oxygen are provided.
  • the invention comprises a method for coking coal, in which the aforementioned coking oven is used in one of the disclosed embodiments, wherein
  • the furnace is filled with coal and the coking process is started ⁇ during coking the concentration of one or more gas components is analyzed
  • This computer unit determines the supply of primary and / or secondary air on the basis of stored discrete values or model calculations, and ⁇ controls the control elements of the shut-off devices for primary and / or secondary air via control lines and thus
  • ⁇ controls the primary and / or secondary air.
  • ⁇ determines the temperature in the coke oven sole and / or the flue
  • this computer unit determines the supply of primary and / or secondary air on the basis of stored discrete values or model calculations
  • ⁇ controls the primary and / or secondary air.
  • the process of the invention is carried out such that the average temperature in the coke oven sole falls in the course of coking to 350 0 C to 400 0 C and 1000 ° C does not fall below. Furthermore, an optimization is to control the oxygen concentration in the exhaust passage constant in the range of 7.5 to 8.5 percent by volume.
  • Fig. 1 shows a coke oven having a coke oven chamber 1 and a coke oven sole 2, wherein the individual chambers or channels of coke oven sole 2 are not shown.
  • the coke oven chamber 1 is connected to the coke oven sole 2 via the gas channel 3.
  • primary air can be supplied via the line, wherein in the line 4, the control valve 7 is arranged.
  • the Koksofensohle 2 5 secondary air can be supplied via the line, wherein in the line 5, the control flap 8 is arranged.
  • the line 9 serves to remove a small gas volume flow from the coke oven chamber 1 and connects the coke oven chamber 1 with an analyzer 10, which is suitable in the illustrated example for the measurement of H 2 .
  • the gas to be measured and conveyed in the line 9 is sucked in by the compressor 11 and conveyed to the analyzer 10.
  • a heat exchanger 12 is arranged for cooling the gas.
  • the gas flow is returned to the coke oven chamber 1.
  • the arranged in the coke oven sole 2 temperature measuring device 13 and arranged in the exhaust pipe 6 lambda probe 14 is shown schematically.
  • the measured values are fed to the computer unit 16 via the data lines 17 and 18, which also receives the measured values of the analyzer 10 via the data line 15.
  • the computer unit 16 controls the control valve 7 via the control lines 19 and thus controls the volume flow of the primary air or the temperature in the coke oven chamber 1. Furthermore, the computer unit 16 controls the control valve 20 via the control line 20, whereby the volume flow of the secondary air and thereby the temperature in the Coke oven sole 2 and oxygen content in the exhaust pipe 6 is controlled.
  • the cooking time could be significantly reduced. It is now possible to reliably achieve a cooking time of less than 48 hours, which represents a significant increase in kiln power over the prior art.
