  • Pot furnace low-temperature calcination process
    Patent number: 11306254
    Abstract: A pot furnace low-temperature calcination process may ensure that, by controlling the flame path temperature and discharge speed of the pot furnace, that the range of the temperature at which the petroleum coke is calcined in the pot is from 1150° C. to 1220° C., and that the discharge speed is 10 to 20% higher than the normal discharge speed and reaches 110˜120 kg/h, reducing the amount of desulfurization of the petroleum coke during the calcination so that the true density of the calcined coke is between 2.05 and 2.07 g/cm3.

  • Pot furnace for calcining petroleum coke at low temperature
    Patent number: 10371446
    Abstract: A pot furnace for calcining petroleum coke at low temperature may include a pot, and a cooling water jacket and a flame path below the pot. The flame path may include eight layers. An inlet of a first flame path layer may be in communication with a volatile channel in the front wall, and is provided with a first flame path layer flashboard An eighth flame path layer may be in communication with a communication flue. Flue gas may be discharged out of the furnace body through a main flue. A furnace bottom cooling channel may be provided below the eighth flame path layer.
