Definitions

  • the invention relates to a method for reducing the NO x content in the flue gas when heating coking ovens with paired heating trains, high and low combustion stages and a flue gas recirculation at the level of the heating flue (circulating current).
  • the invention further relates to a coking oven for performing this method.
  • the known measures for reducing the formation of No x are aimed at reducing the flame temperature through flue gas recirculation or at reducing the oxygen and nitrogen concentrations through partial combustion.
  • Flue gas is mixed into the air and heating gas flow through one or two openings in every second truss wall at the level of the heating mantle, primarily by reducing the maximum flame temperature, but also by reducing the O Z and N 2 concentration the NO x production rates.
  • the NO x reduction principle of partial combustion is used in coking ovens in the form of step heating.
  • a preferred combination with regard to minimal NO x emission provides that the circulating current rate is set between 35% and 45% and the step ratio between 50% and 65% and that the second combustion stage is arranged between 40% and 50% of the heating draft.
  • a coking furnace which is characterized in that the secondary air supply and the secondary lean gas supply to the second, high-lying combustion stages are arranged exclusively within the binder walls delimiting the heating train pairs, the secondary air supply and the secondary lean gas supply open into the neighboring heating trains on both sides of the truss walls and at the same height.
  • the path of the flue gases leads from the flamed heating cable 2 via the reversal point 15 (part via the differential channel 16) into the non-flaming heating cable 2a and via the nozzles and channels 4a, 3a, 6a, 5a, 1 Oa, 9a, 12a, 11 a in the exhaust gas regenerators (not shown).
  • FIGS. 1 and 2 the direction of flow of the media is indicated by arrows for both low and high gas operation. In the case of lean gas operation, however, no heavy gas flows, while in the case of heavy gas operation the lean gas ducts carry combustion air.
  • a heater pair 1 is laterally delimited by the rotor walls 17 and the binder walls 18 passing through the channels 9 and 11.
  • the heating pair 1 is divided into the heating trains 2 and 2a by the binder wall 19 which is penetrated by the reversal point 15 and the circulating current opening 13 becomes.
