Abstract

Since coking coal is characterized by both elasticity and ductility in the plastic state, the coal charge of coke furnaces that contains a plastic layer exerts pressure (coking pressure) on the chamber walls. The pressure exerted depends on the height and mean density of the charge and on the elastoplastic (rheological) conditions. Formulas are obtained for the coking pressure as a function of the height and mean density of the charge and its properties. Those formulas are different for semiindustrial and industrial furnaces. They may be used in the analysis of semiindustrial and industrial coking data.
