Practice of Improving the Temperature and Uniformity of 7.63 m Coke Oven Head
With the long-term operation of the 7.63 m coke oven at Masteel,the heating situation at the furnace head has deteriorated,making it difficult to adjust,and the furnace head temperature does not meet the requirements of coking.In response to this issue,measures such as optimizing and adjusting the size of the nozzle plate and the pressure of the fire hole,increasing the sealing of the heat storage chamber wall and the two forks of the small flue have been taken to reduce the problems of coke cake deviation and smoke generation caused by low furnace head temperature.The application results show that the number of channels with a coke oven head temperature below 1 100 ℃ has decreased by more than 80,and the uniformity coefficient of the furnace head is greater than 0.90.The maturity of coke cake at the head of the coke oven has been significantly improved,and the temperature of coke cake at the head of the coke oven has been raised to above 930℃,greatly improving the cleanliness status of the coke oven.
