Abstract: A recuperator burner comprising a recuperator is disclosed, comprising a tube section serving as a heat exchange surface with flowing fluids, the tube section having a plurality of pleats wound spirally about the longitudinal axis of the recuperator. The recuperator allows an intensive heat exchange between fluids streaming on the inner side and the outer side and can be manufactured using slip casting, due to its simple geometric shape.

Abstract: A process and a device for monitoring the imperviousness of a radiant tube fired by a gas burner is disclosed. From a burner control a burner signal is derived that may have at least the states BURNER OFF when the burner is switched off and BURNER ON when the burner is switched on. In addition, the exhaust gas flow of the burner is monitored and an exhaust gas signal is derived there from which may at least have the states EXHAUST GAS OFF when there is no sufficient volume flow of exhaust gas flowing out of the radiant tube, and EXHAUST GAS ON when there is a correctly flowing exhaust gas. The burner signal and the exhaust gas signal are linked with each other for outputting a failure signal in case the combination BURNER ON and EXHAUST GAS OFF results.

Abstract: A burner for an industrial furnace has a plurality of lines passing through a furnace wall for fuel gas, burner air, and waste gas. Arranged in the furnace space is a combustion chamber (66) in which a mixture of fuel gas and burner air is combusted, and from which a flame (89) is directed into the furnace space. The combustion chamber (66) is delimited by walls (32, 65). The walls (32, 65) are arranged to be movable with respect to one another (65', 65"), so that the volume of the combustion chamber (66) is adjustable (FIG. 2).

Abstract: A burner for an industrial furnace has a combustion chamber arranged in the furnace space in which a mixture of fuel gas and burner air is combusted, and from which a flame is directed into the furnace space. There is further provided an ignition chamber, separate from the combustion chamber, in which a predetermined mixture of burner gas and burner air can be adjusted.
