Embodiment Construction

[0035] figure 1 A receiving container 1 is shown in a quenching car 2 , which has wheels 2 a and is arranged in front of a coke oven chamber door 3 . The coke batch 4 a , 4 b is pushed into the receiving container 1 , and the coke batch 4 is broken into two partial batches 4 a , 4 b by means of a wedge-shaped structural member 5 a arranged on the bottom of the receiving container 1 . This results in an increase in the inner surface of the coke batches 4, so that the quenching water 6 flowing down onto the top of the coke batches 4a, 4b during the quenching operation can also enter inside the coke batches 4a, 4b. The figures also show the push rod 7 of the push machine.

[0036] figure 2 A side view of the same receiving container 1 is shown, in which the push rod 7 of the push machine is included. The figure also shows the axle 2b and the wheels 2a of the quenching car 2 arranged on a track 8 . The hot coke 4 is pushed in the direction of the arrow via a coke table 9 fro...

Abstract

A device for increasing the interior surface of a compact coke charge in a receiving trough, which device increases the interior surface of a coke cake or coke leaving the coking chamber by mechanically breaking apart or roughening it, resulting in a break-up of the coke structure and the formation of crevice-type cavities in the compacted coke charge so that an increased amount of water can flow into the interior of the coke charge during the subsequent quenching step through these crevices, resulting in a high profitability of the method due to reduced quenching times and lower water consumption. A method for increasing the interior surface of a compact coke charge in a receiving trough, which serves to break up a fresh coke cake or to roughen the coke in order to reduce water consumption during quenching is disclosed.

Description

technical field [0001] The invention relates to a device for increasing the internal surface of a compacted coke batch in a receiving vessel, which increases the internal surface of the coke cake and coke leaving the coke oven chamber by means of mechanical crushing or roughening, whereby the coke The structure is loose and allows a plurality of interstitial-like cavities to be formed in the compact coke batch, so that during the subsequent water cooling process, an increased amount of water can flow into these interstitial-like cavities and flow to the interior of the coke batch, so that by using The reduced quenching time and lower water consumption for quenching make the process more economically efficient. The invention also relates to a method for increasing the internal surface of a compacted coke batch in a receiving vessel for breaking up fresh and hot coke cakes or for roughening the coke to reduce water consumption during coke quenching reduce. Background techniqu...
