Abstract
The basic components of a furnace for laboratory coking are considered. The problems encountered in organizing laboratory coking are discussed. Among the features of coking, particular attention is paid to the poor thermal conductivity of the coal charge, which sets limits on the design. Photographs of coke samples obtained in two different furnaces are presented: one furnace has bottom heat supply, while the other has bilateral heat supply. The structure of the coke samples is considered. The coke produced with bottom heat supply has characteristics such as cauliflowers, tar lines, particles of finger and palm type, and also longitudinal and transverse cracks. Such elements are also seen in industrial coke. The coke produced with bilateral heat supply takes the shape of the coking chamber. It consists of many structural elements with sharp corners. The geometry of the coke cake may reflect the specifics of the heat and mass transfer. Accordingly, in designing the furnace for laboratory coking, it is important to produce coke whose geometry resembles that of industrial coke.
