Abstract
METALLURGICAL coke is made by carbonizing coal in an oven that consists essentially of two heated walls spaced some 40–45 cm. apart. Coal is charged into the already heated oven, and the isotherms in the coal are found to be substantially pairs of planes parallel to the oven walls. With the passage of time, both components of any pair of isothermal planes will advance through the charge to the centre of the oven. As the dimensions of the walls are large with respect to their spacing, the system may be regarded for the purpose of analysis as one-dimensional and, if the thermal properties of the charge are known, the temperature distribution at any time should be determinable by solution of the one-dimensional case of the heat-flow equation.
