ABSTRACT:
A heating wall of a coking oven, particularly a horizontal coking oven, separates the coking chamber of the coking oven from the heating flues through which a heating medium flows to heat a charge of coking coal which is contained in the coking chamber. The heating wall is provided with a plurality of individual compartments which are separated from each other and also from the coking chamber and from the heating flues, the compartments being situated between the coking chamber and the heating flues and increasing the rate of heat transmission through the heating wall. Depending on the desired heat-transmission properties of different portions of the heating wall, the compartments may be distributed either uniformly or nonuniformly, or may have the same or different dimensions. The heating wall is constituted by refractory blocks and the enclosed compartments are provided in these refractory blocks. One or more of these compartments may be enclosed within a single block or respective zones of adjacent ones of these blocks may together enclose the compartments. In addition to coking ovens, this type of heating wall can also be used in other applications, particularly where the heating wall is subjected to temperatures exceeding 1000.degree. C. for extended periods of time.
