What effects can high temperatures in the furnace roof space of the carbonization chamber cause?

It’s not the carbonization chamber; it’s the excessive temperature in the furnace roof area.
At present, it is difficult to separate tar from ammonia solution
Just use the coal cake’s depression height, right?
Excessive growth of graphite on the furnace roof affects the yield and quality of chemical products.
Gas and chemical product cracking leads to an increase in carbonized graphite
1. Low heating level. 2. Excessively high volatiles in the coal fed into the furnace, resulting in large coke shrinkage and high temperature in the furnace roof area.
The key now is to consider that the reduction in coal pellets is one of the reasons for the increased temperature in the furnace top space. The temperature is being stabilized first, before measuring the temperature in the furnace roof space.
. . In our plant’s experience, low coal cake levels have never caused high spatial temperatures.
Such a phenomenon has indeed occurred; for example, after a domestic steel company introduced 7.63-meter coke ovens, it was found that the temperature in the space above the oven was consistently high, and graphitization of the oven roof was severe. The reason is an unreasonable design of the heating level for the 7.63-meter coke ovens, combined with the reduction in temperature differences along the height of the coke ovens during segmented heating (which is a advantage)! The high temperature in the furnace top space is mainly related to the heating level! However, some companies have installed SCR systems for desulfurization and denitration, which has had a certain impact on the upper heating of coke ovens; I am currently working with various companies to understand the specifics of this situation! !
