In order to develop a coal preheating process, the effects of coal type and preheating conditions on coke strength were investigated. The blended coal of poor-coking coal 50% and coking coal 50% were preheated rapidly and carbonized by laboratory scale test. The following results were obtained. (1) As a result of investigation of three kind of poor-coking coal, the rapid preheating treatment improves coke strength irrespective of coal type. (2) It was found that rapid preheating treatment of coal improves coke strength in the case of coal blend which consists of six kind of coal. (3) The preheating condition to raise the coke strength has been revealed as follows ; first of all, coal has to be heated up to 330-400℃ ; secondly, it is nessesally to prevent fault heating of coal over 400℃.
