Definitions

  • the pushing sequence of the pusher machine is determined by themaximum current input and when this is compared with the stipulated oven schedule, time relays are activated, after the expiration of preselected time intervals, that shut off the supply of heat to the coke oven battery.
  • the object of the invention is a process for supervising the heating of by-product coke ovens.
  • the object of the invention is to provide a process which makes it possible reliably to avoid such overheatings as a result of deviations of the oven schedule.
  • the method of the invention comprises determining the pushing sequence of a pushing machine associated with the coke oven battery and determining the maximum current input to the pushing machine motors. Then, activating time relays, set to a certain preselected time interval, throttle or shut down the heat supply to the coke oven battery.
  • the pushing sequence of the pusher machine be determined by its current input and compared with the stipulated oven schedule, and that the delays of the pushing sequence, determined in this manner, be used as impulse for throttling or interrupting the supply of heat.
  • Suitable instruments for measuring and recording the current input in the particular pushing of the coke charge, and consequenty, simultaneously for determining the pushing sequence, i.e., the time interval between individual pushing operations, are suitably installed on a central control panel, and are coupled with the control for supply of heat. This coupling can be effected in various manners.
  • one embodiment of a control installation is schematically represented.
  • a maximum contactor 1 is in the ammeter for the pusher ram drive mechanism. When coke is being pushed, the current to the pusher ram drive motors increases to a maximum and the maximum contactor closes. The closing of the maximum contactor 1 activates relay 2. This activation, in turn, activates relays 3 and 4.
  • the time relay 3 in case the next oven has not yet been pushed, at the end of 40 minutes, sends an impulse to the alarm 5 which optically and/or acoustically announces the absence of a push according to schedule.
  • the time relay 4 activates the alarm 6 which, in turn, activates the alternating blast shifting arrangement 7 in such a way that the heating is throttled or rather is shut down.
  • the time after which the prewaming occurs can be selected, for example, at 40 minutes. If operation of the pusher machine is still interrupted after minutes in all, heating is stopped by first closing the gas valves and then centrally throttling the draft to about 4 mm. water gage in the elbows. The operating condition is then safe.
