Abstract of the Disclosure The invention relates to a system for improving the flow in the ducts between the regenerators or recuperators and the combustion chambers of industrial gas-fired systems such as coke ovens. According to the invention, a wedge-shaped refractory brick having at least one oblique surface and formed with vertical bores is inserted into the vertical portion of each duct. This portion has a suitably increased diameter and enters the base of the flue, the vertical sides of the rectangular cross-section brick abutting the inner walls of the duct and the bottom oblique surface extending towards the mouth of the obliquely rising portion of the duct. The sum of the cross-sectional areas of the cylindrical bores is from 0.75 to 1.5 times the flow cross-section of the obliquely rising duct portion.
