Coke oven exhaust gas temperature
Thread Content
What factors generally determine the temperature of flue gas from coke ovens? Why is there such a large difference in the temperature of flue gas from different coking plants?
The temperature of coke oven exhaust gas is related to the type and calorific value of the gas used for heating, as well as to the design of the coke oven and the level of thermal management. In general, coke ovens with excellent design have a relatively stable temperature field!
Buy a book on questions and answers about coking technology; it’s been a long time since I worked in coking
I’ve watched it several times, but I still haven’t found the answer.
Depending on the type of gas used for heating, gas waste gas with a high calorific value has a higher temperature, while gas waste gas with a low calorific value has a lower temperature； The gas leakage rate of the coke oven: when more gas leaks into the carbonization chamber, the temperature rises ； The regenerator is sealed, so there is no air leakage from it; however, the temperature of the waste gases is high. There is air leakage in the brick gas ducts, and this leakage causes air to enter the regenerator where the downward-flowing gas is present, resulting in high temperatures of the waste gases. The management level of coke production is poor, which leads to high energy consumption during coke production and thus high waste gas temperatures as well ；
