Definitions
- the invention relates to a method for reducing the NO content in the flue gas in the heating of coking ovens with paired heating trains, high and low combustion stages and a flue gas recirculation at the level of the heating train floor (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 due to a reduction in the maximum flame temperature, but also by a reduction in the 0 2 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 for carrying out the method according to the invention, 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 in the binder walls delimiting the heating train pairs.
- Embodiments of this coking oven are included in the drawings.
- the direction of the media flow is indicated by arrows during a heating period. Since these are regenerative stoves, the media changes for the second period.
- 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 2 a and via the nozzles and channels 4 a, 3 a, 6 a, 5 a, 10 a, 9 a , 12 a, 11 a in the (not shown) exhaust gas regenerators.
- 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.
