Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the examples, but the protection scope of the present invention is not limited by the examples.
[0017] Such as figure 1 The shown calcined material petroleum coke goes through the entire calcination process from top to bottom in the material tank 2, and high-temperature flue gas flows from the flue 1 to complete the indirect heating process of petroleum coke.
[0018] By controlling the flue temperature and discharge speed of the tank furnace, the calcination temperature range of petroleum coke in the material tank is guaranteed to be 1150°C to 1220°C, and the discharge speed is 10-20% higher than the normal discharge speed, reaching 110-120kg / h, reduce the amount of desulfurization of petroleum coke during the calcination process, so that the true density of the calcined coke is 2.05~2.07g / cm 3 Between them, there are eight layers of fire paths.
