How to deal with excessive pyrosulfur?

What to do when the sulfur content is high and the reaction intensity is low?
The sulfur in coke comes from the coal blend; surely the coking plant can’t add sulfur to it? Therefore, the target for controlling sulfur content in the coal fed into the furnace should not be set too high. There are many factors that affect coke strength, such as the cohesion of the coal fed into the furnace, its bulk density, the heating rate, and the final temperature… It depends on the specific circumstances. If there are many total cracks in the coke and its strength is low, it is likely that too much bituminous coal was used. Similarly, an excess of lean coal results in lower wear resistance of the coke. Over-cooked coke or green coke – no need for further explanation.
Let’s look for problems in the indicators of the blending coal. The intensity of heat and cold is directly related to the temperature of the coke oven, the coking time, and the properties of the blending coal. A thorough analysis will allow us to draw a conclusion.
