An exhaust-gas connection of a combustion space to the exhaust-gas duct 4 of a supply-air/exhaust-gas chimney 1 has an exhaust-gas connection piece 10 which issues into an inlet orifice 8 of the exhaust-gas duct 4 and which runs coaxially to a supply-air connection piece 9a of larger diameter of a connection box 9. In order to achieve a low-outlay connection which can be produced easily and, above all, is permanently leak- tight, a connection block 11 surrounding the inlet orifice 8 and consisting of heat-resistant material is attached firmly to the duct wall, the said connection block possessing a connection orifice 13 which receives the exhaust-gas connection piece 10 with radial play and carrying a sealing plate 15 which consists of asbestos or such like heat-resistant insulating material and which forms a recess 15a adapted to the exhaust-gas connection piece 10 and can be clamped via a clamping ring 16. <IMAGE> |
