Can the coking yield of rammed coking be calculated using volatile matter?
Thread Content
Our company’s coking plant uses the ramming method for coking. Recently, we’ve been facing problems due to high coal consumption. I searched this forum for methods to calculate the coking yield; most of these methods involve using the volatiles content of the blend coal and coke to determine the coking yield. However, none of the formulas specify whether coking is being carried out by top-charging or ramming. I would like to ask whether the formulas available on this forum can be applied to both top-charging and ramming methods of coking ? ? ? Taking into account that the volatility content of the coal is 28-29%, the coking rate comes out to be over 72% but less than 73%! ! !
Most of the calculation methods are empirical formulas based on corporate statistical regression, and they are all based on statistical regression of conventional coke ovens! It can only be used for reference!
The compaction rate for coking at 28-29 degrees reached 76% – could such a low value be due to errors in the measurement of coal and coke amounts? It’s necessary to check the temperature at the center of the coal cake in the coke oven
I misread it; your focal ratio is 72, and with 5% focal dust added, the total focal ratio becomes 75%
