Definitions

  • the invention relates to a device for supplying combustion air into a battery of coking ovens, through which a uniform and effective air or gas supply of these coking ovens in the area above the door opening of the furnace or in the upper door area can be done and this air or gas supply device in the oven ceiling area Air or gas supply channels are supported, which have an adjustment device for gas flow control, which is not exposed to the high temperatures that prevail during coking and filling of the furnace usually.
  • the invention also relates to a method of coking coal with the improved air or gas delivery system.
  • non-recovery or “heat-recovery” furnaces usually takes place by combustion of the gas formed during the coking.
  • the combustion is controlled so that a portion of the gas is burned above the coal charge with primary air in the furnace chamber.
  • This partially combusted gas is fed via channels, which are also referred to as “downcomer” channels, the heating cables in the bottom of the furnace chamber and completely burned here by adding further combustion air, the secondary air.
  • the furnace bank When naming the oven combinations, the combination of several "non-recovery” or “heat-recovery” type coke ovens is called the “oven bank.”
  • a combination of conventional coke ovens is called the "oven battery”.
  • the primary air is sucked from the atmosphere through openings in the doors.
  • the secondary air is sucked through openings in the bottom sockets of the coke oven chambers and passed through channels in the heating cables, which run substantially horizontally under the coke oven chamber.
  • the openings for primary and secondary air are either permanently open or provided with adjusting devices for controlling the amount of air to be sucked.
  • the operation of the coke oven batteries is usually cyclic.
  • a typical coking process usually lasts 20 to 96 hours, after which the coke is removed from the coke oven chamber after the coking process. This is fed to a further processing and the coke oven chamber is refilled without a cleaning process.
  • the doors of the coke oven chambers which are present on both sides of the furnace, are opened and the interior of the coke oven chamber is emptied with a punch to the other side. This process usually takes only a few minutes. Access to the interior of the coking chamber is obtained by opening the oven doors, which are moved to a position above the oven opening for the filling process. There they remain for the duration of the filling.
  • the oven door is usually made of metal and has a thickness of several centimeters. Therefore, the oven door is strongly heated during the coking process. If it is moved into the position intended for the filling operation, the outer wall of the oven chamber located above the oven door heats up very strongly, because the distance of the door from the oven chamber in the filling position is only slight.
  • Existing adjusting devices for the amount of primary air supplied, which are located in this area, can therefore be deformed by the strong heat. the. They then have to be renewed after a few filling cycles. This is associated with increased costs. A deformation of the adjusting device would also mean that they can no longer sufficiently perceive their control function. The result is an uneven coking process and a coke product that has deteriorated quality.
  • the object of the invention is therefore to provide a system for supplying air to a coke oven battery, which takes place above the door construction and is not affected by the heat of an oven door which is in the "open" position Device should cause by their construction no increased costs and still allow a reliable, controllable air supply above the door area as possible.
  • the invention solves this problem by one or more additional openings above the door area, this opening being designed in the form of a nozzle and constructed of a refractory material.
  • nozzles are understood to mean all opening forms which allow air or gas to be introduced into the interior of the oven.
  • the nozzle has no control device and is therefore insensitive to the heat that gives the door after booting during the filling process to the furnace wall and thus to the nozzle construction.
  • the invention solves this problem further by one or more additional air supply ducts through the ceiling portion of the furnace.
  • the additional air supply ducts in the ceiling area of the coking ovens are equipped with means for adjusting the air inlet.
  • a foreign medium instead of air on a case-by-case basis. This can be, for example, a heating gas or an inert gas.
  • the feed devices according to the invention for the primary gas medium also allow a largely weather-independent operation of the coking ovens.
  • nozzles For the construction of the nozzles is used as the refractory material, in particular a silica product.

For better control of the incoming air or gas stream, the nozzles may also be provided with extensions or with spin-generating devices. These may be grooves or suitable air or gas flow devices.
  • the additional air supply ducts in the ceiling area supply the coke oven batteries with additional primary air during the entire or further course of the coking process. They also allow the installation of a control device, as the ceiling area is not exposed to the heat of the retracted door.
