Embodiment Construction
[0037] figure 1 An insert ( 1 ) according to the invention is shown, which is equipped with four nozzles ( 2 ) on the underside. One of these spouts ( 2 a ) is only visible in an obscured manner. The nozzle ( 2 ) points toward the interior of the furnace and to the outside of the opening at an angle α ( 3 a ) greater than 0° relative to a perpendicular ( 3 b ) through the coke oven roof. The primary air (4) enters the insert through the upper side and leaves the insert (4a) at a direction angle.
[0038] figure 2 Also shown is an insert ( 1 ) according to the invention, which is equipped on the underside with four nozzles ( 2 ). The angle α ( 3 a ) pointing outside the opening relative to the perpendicular ( 3 b ) through the coke oven roof is significantly greater here, so that the primary air ( 4 ) flows from above at a significantly wider angle to the coke cake.
[0039] image 3 A coke oven chamber ( 5 ) is shown which includes two inserts ( 1 ) according to the inve...

Abstract
The invention relates to a device for the directed introduction of primary combustion air to the primary heating chamber of a coke oven chamber, the primary air being supplied through inlet openings in the ceiling of a coke oven chamber or to the front walls of the coke oven chamber above the door of the coke oven chamber or in the door of the coke oven chamber or in a plurality of or all of the above-mentioned locations, said inlet openings containing inserts which are fitted with spouts that are directed towards the interior of the oven. Said spouts have an angle which is directed towards the exterior of the opening and which guides the primary air onto the coke cake at a slanted angle so that the air coming from the openings in the coke oven chamber ceiling impacts the coke oven at an angle of less than 90 DEG C and the air coming from the openings in the coke oven chamber wall above the door of the coke oven chamber or in the coke oven door at an angle of more than 0 DEG . The invention also relates to a method for the directed introduction of the primary air using the device according to the invention. The method according to the invention allows a substantial improvement of the mixing of coke gas and primary combustion air in the primary heating chamber.
Description
technical field [0001] The invention relates to a device for the directed introduction of primary combustion air into the coking chamber of a "non-recovery" or "heat recovery" coke oven, wherein the primary combustion air passes through One or more inlet openings in the front or rear coke oven cavity wall are guided, said one or more inlet openings being equipped with means for orienting the inlet flow of primary air so that the filling of the primary air above the coke cake There is a better distribution of gas in the chamber. The invention also relates to a method for operating a coking chamber furnace or coke oven battery or coke grate, wherein the primary combustion air for coking is passed through one or more inlet openings in the cover of the coking oven chamber or through one or more access openings in the coke oven cavity wall of the oven cavity or through one or more access openings in the coke oven cavity door of the oven cavity into the gas-filled chamber above the...
