A pair of adjacent horizontal coking chambers of a coke-oven battery are separated by a longitudinal wall with a multiplicity of vertical heating ducts, the wall being built from blocks which form two parallel frameworks defining the ducts between them. Each framework consists of longitudinal and transverse refractory blocks-preferably of silica-leaving rectangular apertures open toward the ducts and the chambers, these apertures being occupied by refractory plates of lower thermal resistance than the blocks. The transverse blocks of the two frameworks extend overlappingly between the ducts and have interfitting formations holding the frameworks together. The lower thermal resistance of the plates may be achieved by a reduction in wall thickness, compared with that of the over- and underlying longitudinal blocks, and/or by the choice of a more highly heat-conductive material therefor, preferably silicon carbide; in the latter case, tongue-and-groove joints between the frameworks and the plates should leave gaps sufficient for relative thermal expansion which may be filled with grouting and/or elastic inserts.
