Abstract
A dark radiator includes a burner, a fan and a radiant tube which is connected to an exhaust gas discharge line, wherein the burner is connected to a fuel gas supply, wherein the fan is designed to supply the burner with combustion air, wherein the burner is designed to output a flame into the radiant tube, wherein the fuel gas supply is connected to a hydrogen source.
Claims11
A dark radiator, having a burner, a fan, and a radiant tube, which is connected to an exhaust gas discharge line,
- wherein the burner is connected to a fuel gas supply,
- wherein the fan is set up for supplying combustion air to the burner,
- wherein the burner is set up for outputting a flame into the radiant tube,
- wherein the fuel gas supply is connected to a hydrogen source,
- wherein the burner comprises a gas jet and a mixing tube,
- wherein the mixing tube is supplied with hydrogen by the gas jet,
- wherein the mixing tube is flushed with combustion air by the fan,
- wherein the gas jet, together with the mixing tube, forms an ejector,
- wherein the driving medium of the ejector is hydrogen introduced by the gas jet, and the medium drawn into the mixing tube is combustion air situated in the radiant tube,
- wherein an ignition apparatus for igniting the hydrogen/combustion air mixture follows at a distance from the mixing tube in the flame direction, and
- wherein a flashback barrier is arranged in the mixing tube, at an end of the mixing tube directed in the flame direction.
A dark radiator, having a burner, a fan, and a radiant tube, which is connected to an exhaust gas discharge line,
- wherein the burner is connected to a fuel gas supply,
- wherein the fan is set up for supplying combustion air to the burner,
- wherein the burner is set up for outputting a flame into the radiant tube,
- wherein the burner comprises a gas jet,
- wherein the fan is set up for flushing the gas jet with combustion air,
- wherein no fuel gas mixing chamber is provided for pre-mixing fuel gas and combustion air, and the gas jet is supplied exclusively with fuel gas,
- wherein a combustion air mixing chamber is arranged to precede the burner in the flame direction,
- wherein the combustion air mixing chamber is connected to a combustion air source and to the exhaust gas discharge line, and
- wherein the connection between the exhaust gas discharge line and the combustion air mixing chamber comprises a branching-off device by which the ratio of the branched-off exhaust gas volume stream and the combustion air volume stream is determined.
