Can the thermal strength of coke produced in heat-recovery coke ovens reach over 60?
Thread Content
The density of the coke cakes produced by our plant through heat recovery is 0.97. The temperatures at the furnace top and in the six-arch structure are above 1250 degrees. The coking time is 70 hours. The ash content of the coal fed into the furnace is below 10.5%, while the sulfur content is below 0.8%. The volatile matter content on an analytical basis is around 26, with the Y value ranging from 12 to 15. The thermal strength of the coke is 57. Since it is a coal cake used in vehicles, the density of the coal cake cannot be increased any further. Can the heat strength of coke produced using a wide coking chamber reach over 60?
By adjusting the coal blend, the heat strength of the coke reached over 60. It always seems that, with the same coal blending ratio, the quality of coke produced by heat-recovery coke ovens is inferior to that produced by conventional coke ovens.
