Coke oven temperature measurement
Thread Content
The temperature in the same flame channel (for example, chamber 35# with 29 nozzles) is 1320°C at the direct flow temperature, which is 80 degrees higher than the average value℃； At the horizontal temperature, it is 1160℃, which is 120℃ lower than the average. How do I adjust this? Should it be adjusted up or down?
Based on the provided information, the temperature of this firebox is higher than the straight-run temperature and lower than the cross-row temperature, respectively. To adjust the temperature of the coke oven, the following strategies can be employed: 1. In cases where the direct-flow temperature is 80°C higher than the average temperature, it can be adjusted downward appropriately. The fuel supply can be reduced or the amount of combustion air can be increased to lower the temperature. 2. In cases where the horizontal temperature is 120°C below the average temperature, it can be adjusted upward appropriately. The fuel supply can be increased or the amount of combustion air can be reduced to raise the temperature. By taking into account both temperature deviations, the fuel supply and amount of combustion air can be adjusted appropriately so that both temperatures approach the target temperature. The specific adjustment method needs to be determined based on the particular circumstances and the operating parameters of the coke oven. At the same time, it is also necessary to pay attention to maintaining stable combustion and a uniform distribution of temperature at the furnace outlet. .
The same vertical flue in the same combustion chamber?
Yes, the same flame tube in the same combustion chamber.
