Abstract

A partition of high thermal conductivity is provided to separate a furnace heating zone from a furnace reaction zone, the reaction zone being at least partially heated by radiant heat from the heating zone. In a preferred embodiment, the partition means comprises a plurality of individual panels which are arranged in horizontally extending rows across the furnace. A ceramic seal plate is secured over the longitudinal interface between the adjacent panels in the same horizontal row. The seal plates in one horizontal row which extend across the width of the furnace are slightly offset from the seal plates in adjacent rows to compensate for thermal expansion forces which may tend to move the panels and sealed expansion spaces are provided between adjacent panels in the width-wise and longitudinal direction.
