【Basic Knowledge of Haichuan Coke Oven System 007】What to do if the coke oven chute area keeps getting clogged?

Thread Content

The coke oven chute area is located between the combustion chamber and the regenerator, with an internal temperature ranging from 1100 to 1300°C. Its internal structure is complex, with a large number of channels present, including ramps and brick gas ducts. These channels are located quite close to one another, each carrying its own type of gas. There is a significant pressure difference between the upward and downward air currents, but leakage is not allowed. During the construction or operation of coke ovens, it is inevitable that some chutes may become blocked. Addressing these blocked chutes can help reduce damage to the oven structure and extend its service life. Specific steps: 1) First, determine the number of rows of inclined channels that need to be treated; then close the inlet and outlet valves. Next, block the nozzles in the burners of the individual chambers that require treatment, either by using plugs or cotton yarn, and finally restore everything to its normal state. 2) The extended coking time in adjacent carbonization chambers; when dealing with the chutes, try not to load coal to avoid affecting the treatment efficiency. 3) The opposite is true when viewing from the machine-focal side ramp; it is essential to have a clear impression and understanding in mind while handling it, so as to achieve the best results accurately when dealing with the ramp. 4) When using the steel drill, be quick and precise; the first strike must be directed at the center, and the angle should then be adjusted according to the actual situation. 5) It is necessary to use air ducts for purging when the estimated depth reaches 100 mm, in order to carry out further treatment. 6) When lifting the drill rod upward, it is necessary to first align the hole in the operating frame vertically with the firing hole, then lift it slowly; wire should be used to secure it, mainly to prevent the drill rod from deforming and to allow it to be used multiple times. 7) Principles for work requirements: Ensure that work continues even while people rest, so as to complete the arduous task of drilling through the inclined shaft with high quality and efficiency. 8) Safety must be given top priority; during operations, precautions must be taken to avoid burns, crush injuries, blows, and collisions, with everyone watching out for one another to ensure a safe environment free from any hazards. 9) Indeed, piercing through the chute is quite difficult; therefore, a signal for controlled blasting should be given based on the actual circumstances.
