LOW-TEMPERATURE CALCINATION PROCESS OF POT FURNACE

摘要

Provided is a low-temperature calcination process for petroleum coke. The process comprises: controlling the flame path temperature and discharge rate of a pot furnace, so that the calcination temperature of petroleum coke in a material pot is 1150-1220°C, the discharge rate is 10-20% higher than the normal discharge rate and reaches 110-120 kg/h, and the desulfurization amount of the petroleum coke during the calcination is reduced so that the true density of calcined coke is 2.05-2.07 g/cm3. The phenomenon of overcalcination generated in producing calcined coke for a prebaked anode by using the pot furnace is avoided, the desulfurization amount of the petroleum coke during the calcination is reduced, the content of sulfur dioxide in flue gas is reduced, corrosion to silica bricks by sulfur in the petroleum coke is slowed down, the service life of the furnace body is prolonged, and the production capacity of the pot furnace is improved.
