PURPOSE:To improve modulus of elasticity of coal block and to make it possible to carbonize coal block in a chamber oven, by charging a mold with pulverized coal, compression molding the pulverized coal, releasing pressure from the coal block and further compressing the coal block to produce permanent set. CONSTITUTION:Pulverized coal is fed to a mold, compression molded, further molded to give coal block, from which pressure is released. The coal block is further compressed and permanent set is produced in the coal block. A highly elastic block which is fed to a chamber oven and carbonized into coke and has a little smaller dimension than that of the chamber oven. Consequently, self-stability of coal block and stability of handling are improved and cost of installation and power expense are reduced.
