Estimating the term…
A device for feeding primary combustion air or a gas into an oven for the carbonization of coal is provided. The device has nozzle-shaped openings the inlet ports of which are made of a refractory material. These openings are situated above the door area or in the upper door area of the coke oven and having no adjusting devices for the air or gas flow. Part of the primary air or of a gas is passed through these openings. In the top area of the oven additional openings into the oven are provided through which another part of primary air or of a gas is passed and which are equipped with controlling units comprised of a folding mechanism or a helical spindle or a cone lock and connected to a mechanical actuator element. These openings in the oven top area are configured as pipes which pass through the top wall, the pipes being configured, for example, as U-pipes or as a siphon to provide protection from outer influences. Also described is a method for the carbonization of coal that utilizes the devices for feeding primary air or gas, with it being possible to close the nozzle-shaped openings above the door area after the start-up phase of the cokemaking process.
1-46. (canceled)
A device for feeding combustion air for the combustion of coke oven gas into a coking chamber of a coke oven of the “non-recovery type” or “heat recovery type”, comprising:
The device as defined in claim 20, wherein the opening is configured as a sight glass.
The device for feeding primary air or gas as defined in 47, wherein it narrows in its cross section in the course of the pipe run so that a higher flow velocity prevails in the pipe.
Dependencies are inferred from the claim text.
