Description
technical field [0001] The invention proposes a device in the field of non-metallic material processing, specifically a combined calciner for calcining graphite using petroleum coke. Background technique [0002] Petroleum coke is calcined to make ordinary calcined petroleum coke. Usually, a closed dry distillation calciner is used as a petroleum coke calciner. The volatile components in petroleum coke are extracted from petroleum coke by heating up the furnace body to make ordinary calcined petroleum coke. The heat source is the combustion of combustible gas produced by heating petroleum coke. [0003] The heating temperature of petroleum coke in the existing dry distillation calciner is low, usually around 1200°C, so the removal rate of metal elements and non-metal elements in it is low, which affects the quality and purity of the calcined petroleum coke produced. primary product. Contents of the invention [0004] In order to make petroleum coke into low-impurity and ...
