Definitions

  • the present invention relates to industrial furnaces in general, and more particularly to a regenerative industrial furnace, especially a regenerative coking oven battery.
  • one feature of the invention resides in providing, an industrial furnace of the type under discussion, wall means which defines at least one furnace chamber on opposite sides and at least two hollow heat-exchange walls each located at and proximal to one of these sides for exchanging heat with the furnace chamber. At least two regenerators are provided each of which communicates with one of the heat-exchange walls, and means are provided for alternately feeding air and flue gas to these regenerators.
  • both walls bounding the furnace chamber at opposite sides thereof can be programmed, that is both walls can be individually heated in accordance with a desired program or profile, and the chamber and the contents thereof can be supplied at proper times with precisely the requsite temperature, whereas the supply of heat energy can be selectively and at the proper time be terminated when the coking process is completed.
  • the invention can be utilized both in under-fired furnaces as well as in top-fired furnaces and irrespective of the manner in which the heat energy is supplied.
  • FIG. 1 is a diagrammatic fragmentary vertical section illustrating one embodiment of the invention
  • FIG. 2 is a fragmentary top-plan view of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 but of another embodiment of the invention.
  • FIGS. 1 and 2 illustrates a so-called twin-draft furnace which can be under-fired or top-fired.
  • the furnace is under-fired and in conventional constructions the furnace chambers l of which several are provided and which accommodate the coal to be coked will be separated from one another by single heat-exchange walls each of which is provided with a plurality of upright hollow passages for heat-exchange medium.
  • the single heatexchange wall of the conventional constructions is replaced by two heat-exchange walls 2 and 3 which are located at opposite lateral sides of each furnace chamber 1.
  • Reference numeral 10 indicates masonry between these walls, and it will be appreciated that each wall 2 is adjacent the wall 3 of the laterally next adjacent furnace chamber 1.
  • These heat-exchange walls 2 and 3 each associated with one of the furnace chambers 1 are provided, as is especially clear from a comparison of FIGS. 1 and 2 with a plurality of upright passages through which heat exchange fluid can flow in the direction of the arrows indicated in FIG. 1.
  • regenerators 4 and 5 Located below the chambers l and the heatexchange walls, are regenerators 4 and 5 of conventional construction and in the illustrated embodiment each regenerator 4 is connected with one of the heatexchange walls 2 and each regenerator 5 is connected with one of the heat-exchange walls 3.
  • each regenerator 4 is connected with one of the heatexchange walls 2 and each regenerator 5 is connected with one of the heat-exchange walls 3.
  • Previously that is in the prior art, only a single regenerator was provided feeding the single heat-exchange wall located between laterally adjacent chambers 1.
  • Reference numeral 6 identifies conduits which connect the regenerators with the respectively associated heat-exchange walls
  • reference numeral 7 identifies gas supply conduits which are connected via con duits 8 with the respective heat exchange walls 2 and 3.
  • Reference numeral 9 identifies channels which communicate with the regenerators 4 and 5 for supplying to them the requisite air, and also for withdrawing flue gases from the regenerators.
  • heat energy can be supplied much more precisely and selectively to the contents of the respective chamber 1, in that heat can be supplied via the heat exchange wall 2 associated with the chamber, via the wall 3 associated with the chamber, or via both.
  • the regenerators are of course of known construction and it is not believed necessary to discuss them in more detail, inasmuch as the concept of the invention lies not in the manner in which the heat energy is generated, but in the manner in which it is supplied to the respective chamber 1.
  • FIG. 3 differs from FIGS. 1 and 2 in showing a different furnace in which during one heating period half of the heat exchange walls is subjected over half of their respective overall height to the action of flames, with the flue gases or combustion gases leaving through a channel located above the heat-exchange walls and flowing downwardly back to the regenerators through the other heat exchange walls, that is the heat exchange walls which are not being heated during this period. After such a heating period is completed, the flow direction of the hot gases is reversed, and consequently, each of the regenerators alternately receives air and flue gases in alternating heating periods.
  • Such furnaces may also be under-fired or top-fired, and what is essential is that here as in the embodiment of FIGS. 1 and 2, each of the chambers 1 again has associated therewith two heat exchange walls located at opposite lateral sides thereof.
  • wall means defining at least two laterally adjacent furnace chambers each having opposite sides, and at least two pair of heat-exchange walls having hollow unconnected interiors, the walls of each pair being located at and proximal to the respective sides of each furnace chamber for exchanging heat with said respective furnace chamber; a plurality of regenerators communicating with respective ones of said heat-exchange walls so that each of said walls can be heated independently of the others; and means for alternately feeding air and flue gas to said regenerators.
  • each of said heat-exchange walls extends along a respective side of one of said chambers and is provided with a plurality of internal passages communicating with one of said regenerators.
