-1- ABSTRACT OF THE DISCLOSURE A device for improving the flow of gases flowing through ducts into the combustion chamber of industrial gas- fired systems, and more particularly coke ovens, with regenerative or recuperative recovery of heat from the waste gases, preheated combustion media such as air in the case of rich gas firing or air and lean gas in the case of lean gas operation being introduced through the ducts from the heat- exchanger outlet into the heating flues. The device is characterised in that the conventional heating-flue base is replaced by an oncoming flow plate, preferably with cylindrical bores, the plate being somewhat thicker than the flue base and disposed above a chamber which is divided in a gas-tight manner by a central refractory web into two halves, each receiving a duct, the ratio of the height a of the free space to the thickness L of the oncoming-flow plate being 0.3 to 0.7, preferably 0.5.
