Abstract: A radiant heating tube device with a fuel-heated burner and a flame tube located inside the radiant heating tube often shows an undesirable increase in temperature in the area of the closed end of the radiant tube. This temperature rise can be reduced by installing an additional tube or other flow body in the area of the end of the flame tube. This achieves a more uniform radiant tube surface temperature.

Abstract: A furnace heating device is provided for the heating a furnace chamber, comprising: at least one radiant tube, configured to heat the furnace chamber and which can be heated using a burner, which can be operated in a first operating mode with a flame and in a second operating mode with flameless combustion, a burner control device, configured to control on and off states and operating mode setting for the burner of the radiant tube, wherein said burner control device is configured to determine when a temperature (T) of the furnace chamber lies above a critical temperature (Tk), which must at least be present in a combustion chamber for safe operation of flameless combustion, wherein there is a single safety monitor for monitoring the temperature within said furnace chamber and communicating said temperature to said burner control device and wherein said burner control device is configured to send a signal to not send a signal to start said flameless combustion when it is determined that said temperature (T) o

Abstract: A recuperative gas burner for industrial applications can include a combustion chamber and a burner tip providing an outlet opening of the combustion chamber. The gas burner includes a gas supply for combustion gas having a first gas supply duct and a second gas supply duct. The combustion gas can be provided to the combustion chamber through the first gas supply duct. The combustion gas can also be provided to the burner tip through the second gas supply duct. The gas burner can include an air supply for combustion air and an exhaust gas flow channel for exhaust gas, wherein the exhaust gas flow channel and the air supply are configured such that combustion air can be heated by the exhaust gas.
