Coke oven temperature
Thread Content
Modern coke ovens can be charged either from the top or by tamping. Due to the broken rammer, coal cannot be loaded, but coal loading can still be carried out using a top-loading coal car. The question is: for the mixture of coal used in ramming coke ovens, which is fed into the ovens using a top-loading method, should the standard temperature be changed while keeping factors such as the turnaround time constant?
Regarding the mixture ratio of compacted coke, when coal is loaded using the top-loading method, the bulk density will certainly not meet the required levels. Can the coke produced in this way satisfy the specified requirements?
It is necessary; as the coal loading amount changes, the standard temperature also needs to change accordingly.
It is definitely necessary; it’s not just a matter of standard temperature. If compacted coal material and specific mixtures are used and fed into the coke oven, even if the temperature remains at standard levels during production, the quality of the coke will still not meet the original standards.

Everyone knows that the requirements cannot be met, as it is a coke oven that has been converted from a top-charging type to a tamping type – it can operate in either mode. If the conversion from tamping to top-charging is planned, coal can be prepared in advance. This time, a sudden failure of the rammer occurred, so the coal that needed to be rammed had to be loaded into the coke oven using a top-loading method. At the very least, the density is lower, which means the weight is less; therefore, the temperature needs to be changed. If nothing is changed, are there any other consequences besides the substandard quality of coke? Such as difficulty in pushing out coke, etc
It is necessary, because the bulk density has changed
