How to determine coking in heating furnace tubes?
1. After coking, the temperature at the furnace outlet increases； 2. The pipeline resistance of the heated medium will increase.
The flue gas from the firewall rises steadily, while the oil outlet temperature of the furnace tubes increases sharply in a linear manner.
No, it should be that the pressure and temperature in the furnace rise, while the outlet temperature responds slowly. There are dark spots on the furnace tube.
1. Increased fuel consumption 2. Rising furnace temperature 3. Severe drop in furnace exit temperature 4. Bright spots observed on the furnace tubes
