ABSTRACT:
A refractory brick is installed in a transfer flue with vertical orifices disposed between, on the one hand, the regenerators or recuperators and, on the other hand, the combustion chambers of industrial gas-fired systems, particularly a coke oven. The refractory brick has parallel surfaces and the length of the orifices in the brick is at least six times their diameter. The sum of the cross-sectional areas of the orifices is from 0.75 to 1.5 times the flow cross section of the upwardly-inclined portion of the transfer flue. The cross sections of the orifices can be cylindrical or elliptical. The orifices can be longitudinal slots whose cross-sectional areas are bounded by semicircles and whose cross-sectional length is not greater than three times the diameter of the semicircles.
