What indicators are more appropriate for assessing the quality of coke in dry quenching?
Thread Content
In our plant, the cold strength of coke is evaluated using the M40 standard to determine its quality. After the introduction of dry quenching, the particle size of coke decreases significantly; the proportion of coke particles larger than 60 is very low, generally not exceeding 20%, while the proportion of particles between 40 and 60 is higher, with an average particle size of around 48. Should we consider using the M25 standard to evaluate the cold strength of coke? The reasons are as follows: 1. When using M25, it is sufficient to use coke with a value greater than 40, which provides better representativeness. 2. It is more convenient for M25 sampling. 3. When comparing coke with a calorific value greater than 60 to that in the 25-60 range, the latter has a better heat intensity. We welcome everyone to discuss which indicators would be the best for measuring the cold strength of coke produced by dry quenching.
Are there any colleagues who have done a lot of research on this topic? Let’s exchange ideas
Everyone is using this for the M25 now; the M40 has too large a range and isn’t suitable
