Definitions

  • the invention relates to a method for heating coke ovens with the aid of circulating currents in the heating trains and to a device for carrying out the method.
  • the aim of heating coke ovens is to achieve a well-cooked coke of uniform quality through uniform heating.
  • the invention proposes that the intensity of the circulating currents in the heating trains be designed continuously or discontinuously by means of a constructive design of the sizes of the circulating current and / or reversal point cross sections between the increasing and decreasing heating trains from the machine to the coke side of the furnaces.
  • the intensity of the circulating current is understood to be the amount of the flue gas drawn back in relation to the amount of flue gas formed from the freshly supplied combustion media, gas and air.
  • the invention initially provides that this variation from the machine to the coke side decreases.
  • the variation of the circuit current intensity can be carried out continuously from one pair of heating trains to the next, or in stages.
  • a gradation in groups can be understood to mean a gradation from group to group from the machine to the coke side, with several pairs of heating trains each forming a group.
  • the grading of the circuit current intensity in a heating wall can also be done discontinuously. For example, it can be carried out in small increments in part of the heating trains of a heating wall, while small increments are then realized again in the subsequent heating trains.
  • the flow conditions in the first part of the heating wall should be in a small scattering range with laminar flow and in the other part of the heating wall in a small scattering range again with turbulent flow.
  • the circulating current has a self-regulating effect.
  • This self-regulating effect of the circulating current consists in the fact that the amount of circulating current decreases as the furnace output increases, while the amount of smoke gas sucked in increases as the heating output decreases.
  • This effect means that the flame lengths can be kept almost constant even with fluctuating furnace outputs over a wide range.
  • This effect also meets the heating requirements in composite stoves.
  • a lower circulating current is required for low gas heating and a stronger one for high gas heating. Since larger amounts of exhaust gas are primarily generated with lean gas heating than with high-gas heating, a lower flue gas return is automatically established with lean gas heating due to the self-regulating effect. With its self-regulating intensity effect, the circulating current automatically almost compensates for the requirements of the different types of underfire gas.
  • the settings of the circulating current intensities in the different heating trains of a heating wall are chosen by design or regulation of the resistances in the flow paths so that the self-regulating effect of the circulating current is optimally used in the event of a change in output or gas type of the furnace heating.
  • the invention provides that the cross-sections are varied individually or together from machine to coke side over the entire wall length or in zones . If changes are made together, they can be proportional, in the same direction or in the same direction.
  • the invention provides that the intensities of the circulating currents in the heating trains are increased by additional gas jets Speed in a manner known per se from DE-OS 21 61 638 - if necessary differently - be amplified.
  • the total cross-sections per circuit or reversal point consist of one or more openings. It is possible that each or individual of these openings with one or more throttle members, for. B. slides or flaps are provided, which also allow control of the circulating current during operation.
  • the invention provides a device for heating coke ovens, in which the heating walls adjacent to the coke ovens are divided into pairs of heating trains from the machine side to the coke side of the coke oven battery and the partitions of the two heating trains of a pair of heating trains each have one or more circulating current at their lower ends. Openings and at their upper end each have one or more reversing point openings, to which control instruments such as flaps, slides or the like are assigned, which is characterized in that the cross sections of the circular flow openings and / or the reversing point openings differ from the machine to the coke side of the coke oven battery are large.
  • twin heating trains With 1 and 2 the two heating trains are designated. which form a pair of heating cables and are alternately flamed upwards in a known manner.
  • This pair of heating trains - also called twin heating trains - represents a section of a heating wall, which consists of a large number of twin heating trains connecting to the left and right up to the machine or coke side.
  • the partition 3 of the heating cables 1 and 2 has at its lower end two circular flow openings 4, each of which can be closed with one or more flaps 5 in the present case.
  • the cross sections of the circular flow openings differ from the machine to the coke side.
  • the heating cables in the illustrated embodiment are connected to one another by two openings 6 and 7, the so-called reversal points, one above the other.
  • each of these openings is assigned a roller 8 or 9, which can completely or partially release this opening or also practically completely close it.
  • the cross sections of the two reversal points are preferably designed differently from the machine to the coke side, just like that of the circular flow openings.
