How is the 6-2 sequence concatenated?
Thread Content
9-2, 5-2, 2-1 – these sequences are well-known to everyone. Recently, when preparing the construction plan, sequence 6-2 was needed for removing the partition walls; those who know how to arrange these sequences could please give some advice. Thank you!
1 7 13 19 25..... 3 9 15 21 27..... 5 11 17 23 29..... 2 8 14 20 26..... 4 10 16 22 28..... 6 12 18 24 30..... For reference only; please correct any errors
I’ve never heard of it. The principles for determining the sequence of coke pushing are as follows: 1. Improve the efficiency of the equipment, shorten the movement distance of mechanical devices, and reduce unnecessary losses; 2. Ensure that both sides of the coke coking chamber are in the middle stage of coking, so as to maintain an appropriate expansion pressure； 3. Carry out even coking and coal charging along the length of the furnace bank to prevent localized overcooling or overheating of the furnace structure, thereby ensuring uniform furnace temperature and uniform pressure in the gas collection pipes.
What the original poster is referring to is not the sequence for pushing coke, but rather the sequence for removing the sealing wall; therefore, the following issues do not apply: 1. Improving the efficiency of the equipment, reducing the movement distance of mechanical devices, and minimizing unnecessary losses; 2. Ensuring that both sides of the coke coking chamber are in the middle stage of coking, so as to maintain an appropriate expansion pressure； 3. Carry out even coking and coal charging along the length of the furnace bank to prevent localized overcooling or overheating of the furnace structure, thereby ensuring uniform furnace temperature and uniform pressure in the gas collection pipes. Of course, a 6-2 sequence is not very suitable for normal furnace discharge and coke pushing
I’ve also never heard of the 6-2 sequence; but for simply bypassing a firewall, it’s actually not necessary to go through such complicated procedures. Under normal circumstances, it is sufficient to remove one layer at a time. The main thing to note is that the sealing of the coke side wall in one carbonization chamber should not be carried out simultaneously; also, it is better not to remove the end walls first. Taking a 50-hole coke oven as an example, the sequence for removing the sealing walls can be: machine side: 3, 1, 5, 7---------- ； Charged sides: 48, 50, 46, 44--------------.
Haven’t heard of it; it’s the first time I’m hearing about a 6-2 sequence as well
A new term has emerged; I don’t think there’s such a thing as 6-2 reordering. There must be certain differences between solid fuel, liquid fuel, and gas fuel furnaces when it comes to wall removal
If only the fire bed is cleaned without adding coal, it’s not necessary to follow a strict sequential order; working in odd and even numbers is also acceptable
