Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method and device for measuring and calculating the burning loss rate of metallurgical coke. Background technique [0002] In the coal coking industry, dry coke quenching is generally used to cool red coke. During the process of dry coke quenching, due to the CO 2 and O 2 The existence of red coke has caused the red coke to be continuously oxidized and burned. In the production process, the burning loss ratio of red coke should be controlled as much as possible to reduce the coke loss in the process of dry coke quenching. Reducing the burning loss rate of CDQ is a difficult point in the CDQ industry at present. There are also many methods for calculating the burning loss rate. How to calculate it accurately is also a topic often discussed in the industry. [0003] At present, the commonly used methods for calculating the loss rate of red coke are: coal consumption method ...
