Abstract

Heating boiler with integrated waste gas recirculation for the combustion of liquid or gaseous fuel, having a furnace insert open in the direction of flow and a burner arranged on the front side, a part of the flue gas being recycled into the flame thereof for cooling the flame temperature and hence reducing the formation of NOx, in such a way that, in the interest of an overall optimised temperature characteristic, the flue gas fraction fed to the flame is tapped downstream of a first cooling section and passed into a region in the form of a cylindrical pipe around the flame formation zone.
