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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
