Definitions

  • regenerator compartments are longitudinally separated by a wall, and the connecting flues for the upper located burning points are connected to one of the wall-separated portions or spaces and the connecting flues for the lower located burning points are connected to the other longitudinal part. Furthermore, to each regenerator space obtained by the longitudinal division within the regenerator compartment by the longitudinal division of the sole flues, an independently closable or controllable flue is correlated which is regulated by means of the regulating device (not shown).
  • the flowing mediae can be adjusted at the burning points of the heating walls so that also in extremely high furnaces a distribution of the temperature is obtained adapted to the actual heat requirement of the furnace chambers not only as heretofore in a horizontal, but also in a vertical furnace direction, since when the requirement arises it is not only possible to adjust within a group of heating flues the consumption of combustion mediae for the upper and lower burning points independently from each other, but also the consumption of mediae of the upper or lower burning points of groups of heating flues towards groups of heating flues.
  • each wall of the girder separating the heating flues is provided with an upper and a lower located burning point opening and these openings are connected by flues extending parallel in a sectional plane with different longitudinal parts of a compartment of the regenerators arranged below the heating walls, for lean or poor gas heating being effective in pair (air and lean gas in exchange with waste gas).
  • the stacks which support the higher located openings can be combined in a simple and stable way with the girders for instance by placing two bricks provided with two passage cross sections onto each other within the girders or transverse walls.
  • the inlets for the intense burning gas may be arranged thereby in the center of the heating flue between the stacks leading to the higher located openings.
  • FIG. 1 shows a half of a symmetrical coke furnace in a longitudinal section along a heating wall and through the regenerators and lines;
  • FIG. 2 illustrates a partial cross section through the heating flues and regenerator furnace chambers and heating walls
  • FIG. 3 is a partial cross-sectional top view of two neighboring heating walls on a larger scale.
  • reference numeral 1 is the furnace chamber and 2 are the heating walls, which are provided with heating fiues 4 divided by girders 3. Heating flues 4 are combined at the oven quoins or the head ends of the chambers 1 to form twin groups 5 and with the remaining ends combined to quadruple groups 6.
  • First transverse division walls 3 constitute some of the girders, while second transverse division walls 3' serve also to group the flues into their predetermined groups of two 5, or groups of four 6, as indicated.
  • each heating flue is provided with a lower located burning point consisting of two bottom openings 7 and a higher located burning point consisting of two higher located openings 8 at the end of stacks 9, as well as a nozzle 10 through which in the case of intense gas heating intense gas enters, whereby then air escapes from all the openings 7 and 8 of the burning up heating flues.
  • a lower located opening 7 and a higher located opening 8 are provided, the latter at the end of stacks 9, which are constructed in a doublesmokestack-like manner by means of bricks inserted into or built within the girders 3 in such a way that the upper and lower located openings of each heating flue 4 are standing diagonally towards each other.
  • the intense or rich gas nozzle 10 is located in the center of the heating flue 4 between the stacks 9 for the upper located burning points.
  • regenerator 13 Each pair of openings 7, 8 located at the girder wall is connected by a pair of conduits 11, 12 with one regenerator 13 which conduits are provided below the furnace chambers 1 and the heating walls 2, and accordingly always conveys similar mediae.
  • Regenerators 13 are divided into correlated compartments 15 to 19 by cross walls 14 which are correlated with respective individual heating groups 5 and 6. Furthermore, by means of a longitudinal wall 20 extending from head, to head a division is made of the regenerators 13 into two longitudinal parts 21 and 22, which parts 21 and 22, respectively, are connected with the heating flues 4 via the respective conduits 11, 12 of each pair of conduits.
  • Sole conduits 24 to 28 are divided by longitudinal walls 23 extending from the coke and machinery side to the individual regnerator compartments 15 to 19, so that at the front side of the sole conduits on which the regulating devices for the flowing mediae are provided (not shown in the drawing), two cross-sectional openings 29 and 30 are obtained for each sole conduit 24 to 28.
  • the crosssections 29 and 30 are adjustable independently of each other, and determine the inflow and outflow of the mediae at the upper and lower located burning point openings of a group of heating flues.
  • an improved regenerative coke furnace having upper and lower located burning points within a plurality of heating flues which flues are constituent parts of heating walls and are formed by first and second forms of transverse division walls of which the second form of walls act to combine the heating fiues into separate predetermined groups and having regenerators sub-divided by spaced walls forming a plurality of regenerator compartments corresponding to and correlated with said groups of heating flues and said compartments being connectable by means of sole conduits with regulating devices adapted to be arranged at the exterior side of the furnace and said sole conduits for feeding the flowing mediae such as air, lean gas, and for drawing off waste gases, the improvement for obtaining more uniform heating of the furnace by structure enabling independent controllability of the upper and lower burning points in related heating flues and related groups of heating flues, the improved structure comprising in the combination wall means dividing each of said regenerator compartments into two longitudinal half parts; first connecting conduits connecting each of the respective lower located burning points in communication with a respective first one of said longitudinal
  • a regenerative coke furnace as defined in claim 2 further including intense or rich gas inlets arranged in the center of each of said heating flues between stack means forming and leading to said upper located burning point openings.
