Abstract
Methods for evaluating whether there is a probability that coal will reduce the strength of coke using an apparatus including a stirrer. A degree of entanglement (a−b)/a represented by the heights a and b, or the height a only, is used as an evaluation index for coal, where a height of the semicoke on an inner wall of the container is represented by b, and a height of the semicoke on the stirrer is represented by a. Semicoke formed from heated coal is formed in the container using the degree of entanglement as an evaluation index.
