Scope of purpose: Use a tank calciner to heat and calcinate petroleum coke to meet the quality requirements. It mainly includes calcined feedstock, tank furnace calcining system, and calcined coke transportation equipment.
1. Technical conditions
1. The temperature of the first fire path is 1150～1300℃, and the negative pressure is 10～30Pa. 12pa
2. The temperature of the three-layer or four-layer fire path is 1150～1300℃, and the negative pressure is 20～80Pa. 60pa
3. The average temperature of the flue is not more than 800℃, the individual measuring points are not more than 1000℃, and the temperature of the flue with the waste heat boiler is not more than 300℃.
4. The cooling water outlet temperature of the discharge tank is lower than 60℃, and the temperature of the coke discharged after forging should be lower than 250℃.
5. The true density of the calcined coke is not less than 2.04g/cm3, the powder resistivity is not more than 650Ω.mm/m, the volatile content is less than 0.5%, the ash content is less than 0.6%, and the moisture content is less than 0.5%.
2. Production operation
1. Under normal production conditions, add materials at regular intervals in each shift, keep the material on the furnace head sealed tightly, and do not allow the phenomenon of empty furnace head.
2. Adjust the discharge amount according to the quality of the calcined coke, and discharge less frequently, so that the material in the furnace is in a state of frequent movement, and the interval between two discharges is not more than 10 minutes.
3. Frequently clean volatile sub-channels and vertical channels to keep them unblocked. Make full use of the volatile matter, and try to make it burn in the first and second floors. Only the waste heat boiler is allowed to burn the excess volatile matter in the fire channel of the last layer.
4. When the power is cut off, the water is cut off, the smoke exhauster is stopped, or there is no raw material, the discharge should be stopped, and the height of the material surface should be above the furnace neck. When production is stopped for a short period of time (1 to 2 days), the temperature of the fire channel should be kept above 1000℃, and the temperature of the fire channel should be kept at 900±20℃ for more than three days.
5. During the temperature adjustment process, check the combustion situation in the fire channel regularly, adjust the fuel and air ratio in time according to temperature changes, and deal with the blockage of the fire channel and air leakage in time.
3. 　Equipment inspection:
The equipment screws are fixed and tightened, the water tank of the calciner is leaking, the crushing and discharging equipment is operating normally, the vibration conveying and lifting equipment is normal, the lubrication of each lubrication point is in good condition, and the temperature of each motor and bearing should not exceed 60℃.
