Definitions

  • the invention relates to a bright radiator, with a burner, a fan and a radiant plate serving as a radiation surface and provided with flame passage channels, the burner being connected to a fuel gas supply, the fan being set up to supply combustion air to the burner, the burner being set up to cause a flat glow of the radiant plate.
  • infrared heaters are often used to heat production and storage facilities. These generate infrared radiation, which is used to generate heat.
  • infrared heaters over conventional heating systems is that they emit their heat with almost no loss. On the other hand, drafts that occur in conventional combustion systems are avoided.
  • Infrared heaters are divided into light and dark heaters. While in dark radiators the heat is generated by combustion of a fuel gas-air mixture in a closed tube, in which the surface of the pipe heated by the hot gases generated gives off the heat predominantly as radiation, in bright radiators a fuel gas-air mixture is used on the surface of one or more of these arranged ceramic radiant panels burned. Either natural gas or liquid gas (propane gas or biogas) is used as fuel.
  • the name bright radiator is based on the visible combustion of the fuel gas and air mixture on the ceramic radiant plate, which causes it to glow.
  • the ceramic radiant plate has flame passage channels arranged parallel to one another with, often conical, recesses on the radiation side.
  • the modern bright spotlights have proven themselves in practice and have relatively low pollutant emissions while at the same time being highly efficient.
  • the present invention is based on the object of providing a bright radiator whose pollutant emissions are further reduced while maintaining at least the same level of efficiency. According to the invention, this object is achieved by the features of the characterizing part of patent claim 1.
  • the invention provides a bright radiator which has at least the same level of efficiency compared to the prior art and in which pollutant emissions are reduced. Because the fuel gas supply is preferably connected exclusively to a hydrogen source, the exhaust gas theoretically does not contain any carbon-containing pollutants such as carbon monoxide, carbon dioxide or hydrocarbons, since hydrogen does not contain any carbon.
  • the hydrogen supply and the blower are designed and aligned in such a way that the hydrogen flow and combustion air flow are set at an angle to one another, the angle preferably being less than or equal to 90 degrees and greater than or equal to 45 degrees. This ensures good mixing of hydrogen and combustion air.
  • a reflector is arranged which surrounds the radiation surface of the radiant plate and which delimits an exhaust gas space, with a combustion air mixing space being arranged upstream of the burner, which is connected to a combustion air source and the exhaust gas space.
  • the exhaust gas space is connected to the combustion air mixing space via an ejector, the driving medium of the ejector being combustion air introduced by the fan and the medium sucked into the combustion air mixing space being exhaust gas located in the exhaust gas space.
  • An adjusting device is preferably arranged, via which the ratio of the combustion air volume flow to the sucked-in exhaust gas volume flow of the ejector can be adjusted.
  • the combustion air mixing chamber is arranged within the blower. This ensures good mixing of combustion air and exhaust gas.
  • the hydrogen supply is guided over a surface area via a distributor plate which is arranged parallel to the jet plate and which delimits a fuel mixing chamber.
  • a distributor plate which is arranged parallel to the jet plate and which delimits a fuel mixing chamber.
  • the fuel gas supply can also be connected to a hydrogen-combustion air mixture source, with the hydrogen concentration in the mixture being supplied above the upper explosion limit, which is why the hydrogen-combustion air mixture is not ignitable. In this way, only a very low oxygen content is required in the combustion air introduced into the mixing chamber.
  • a supply air duct which encompasses the distribution plate at least in some areas and is connected to the blower is arranged.
  • the supply air duct is preferably designed in such a way that a flat flow of combustion air over the distributor plate is achieved. This results in uniform mixing with the hydrogen flowing through the distributor plate.
  • an optical sensor is arranged which is set up to detect at least one parameter of the flame generated by the burner.
  • the sensor is advantageously a UV sensor. This achieves flame detection of the invisible hydrogen flame.
  • the optical sensor is aligned with the radiant plate, preferably at an obtuse angle. This achieves reliable flame detection.
  • a reflector is arranged which surrounds the radiant plate at least in some areas and is provided with a window, the optical sensor being aligned from outside the reflector through the window onto the radiant plate. This achieves flame detection in a position of the sensor that is protected from heat.
  • the optical sensor is connected to an adjusting device connected to the blower for interrupting and/or adjusting the combustion air supply.
  • the optical sensor is preferably connected to an adjusting device connected to the fuel gas supply for interrupting and/or adjusting the hydrogen supply. This influences the combustion air-hydrogen mixture or even a The hydrogen supply can be switched off depending on the flame status.
  • the adjusting device is connected to a control and regulation module which is programmed to regulate the flame properties based on stored target parameters by changing the quantities of hydrogen and/or combustion air.
  • the bright spotlight chosen as an exemplary embodiment according to Figure 1 comprises a burner 1, which is connected to a hydrogen supply 2 and a fan 3.
  • a reflector 4 is arranged to encompass the burner 1.
  • the burner 1 includes a fuel mixing chamber 11, which is delimited by a ceramic radiant plate 12.
  • the ceramic radiant plate 12 is provided in a known manner with a hole pattern extending over the entire surface, which is formed from cylindrical flame passage channels which are designed to widen conically on the outward-facing side of the radiant plate 12.
  • a hydrogen supply 2 is arranged orthogonally thereto, which opens into the fuel mixing chamber 11. Opens at right angles to the hydrogen supply 2 a pressure line 31 in the fuel mixing chamber 11, which is connected to the blower 3.
  • the blower 3 is connected on its suction side to an ejector 32, the drive connection of which is connected to a combustion air supply 33 and the suction connection of which is connected to an exhaust gas supply line 34, which is passed through the reflector.
  • a recirculation aperture 35 is arranged in the exhaust gas supply line 34.
  • the combustion air flow sucked in by the fan 3 through the combustion air supply 33 serves here as a driving medium, through which part of the exhaust gas cushion 381 located within the reflector 4 is sucked in through the recirculation aperture 35.
  • the proportion of the exhaust gas flow in the combustion air flow can be adjusted through the recirculation aperture 35, which in turn determines the oxygen content of the exhaust gas-combustion air flow mixture.
  • the remaining exhaust gas stream flows out of the reflector 4 into the ambient air.
  • a combustion air mixing chamber 39 is integrated into the blower 3.
  • the fuel mixing chamber 11 is supplied with an exhaust gas-combustion air mixture by the fan 3, which is ignited with the hydrogen stream introduced through the hydrogen supply 2 after exiting through the radiant plate 12 by an ignition electrode 13 arranged on the burner 1 outside in front of the radiant plate 12, whereby a flame carpet is created on the outside of the radiant plate 12.
  • the combustion essentially takes place in the conically widened sections of the flame passage channels of the radiant plate 12, whereby the latter is heated to a bright red glow on its outer surface.
  • the flame temperature can be regulated by the oxygen content of the exhaust gas-combustion air flow mixture, which can be set via the recirculation aperture 35.
  • the burner 1 is designed in accordance with the previous exemplary embodiment and is in turn surrounded by a reflector 4.
  • a hydrogen supply 2 is arranged orthogonally thereto, which opens into the fuel mixing chamber 11.
  • a pressure line 31 opens into the mixing chamber, which is connected to the blower 3.
  • the blower 3 is connected on the suction side to a combustion air supply, an ejector 36 being inserted in the pressure line 31 within the reflector 4, through which a suction gap 37 radially spanning the pressure line 31 is formed.
  • the section of the pressure line 31 adjoining the ejector 36 forms the combustion air mixing chamber 37.
  • a sensor receptacle 41 which has a window 42, is inserted into the reflector 4.
  • a UV sensor 43 is inserted into the sensor receptacle and is connected via an electrical line 44 to an adjusting device (not shown) for interrupting the hydrogen supply.
  • the UV sensor 43 is aligned at an angle of 45° to the radiation plate 12. If no flame is detected by the UV sensor 43, the hydrogen supply is interrupted by the adjusting device.
  • the actuating device or a control and regulation module connected to it can also be additionally connected to the ignition electrode 13 and set up in such a way that in the event that no flame is detected, the ignition electrode 13 is first activated and only after a further absence of a flame is an interruption the hydrogen supply takes place.
  • a burner 5 is arranged, which in turn is connected to a fan 3.
  • the burner 5 includes a fuel mixing chamber 51, which is delimited by a ceramic radiant plate 52.
  • a hydrogen supply 2 is arranged orthogonally thereto, which opens into the fuel mixing chamber 51.
  • a distributor plate 53 is arranged parallel to the jet plate 52.
  • the distribution plate 53 is provided over its surface with a hole pattern formed from cylindrical bushings.
  • the hydrogen supply 2 is connected to the distributor plate 53 via a hood-shaped section 21, so that hydrogen flows through the distributor plate 53 over a flat area.
  • the fuel mixing chamber 51 is arranged surrounding a supply air duct 54, the nozzles 55 of which are aligned in an imaginary plane parallel to the distributor plate 53.
  • the supply air duct 54 is connected to the fan 3, through which it is fed.
  • the blower 3 is connected on its suction side in accordance with the first exemplary embodiment to an ejector 32, the drive connection of which is connected to a combustion air supply 33 and the suction connection of which is connected to an exhaust gas supply line 34, which is passed through the reflector 4.
  • a recirculation aperture 35 is arranged in the exhaust gas supply line 34.
  • the combustion air sucked in by the fan 3 through the combustion air supply 33 serves here again as a propellant medium, through which part of the exhaust gas cushion 381 located within the reflector 4 is sucked in through the recirculation aperture 35.
  • the proportion of the exhaust gas flow in the combustion air flow can also be adjusted here through the recirculation aperture 35, which in turn determines the oxygen content of the exhaust gas-combustion air flow mixture.
  • the remaining exhaust gas stream flows out of the reflector 4 into the ambient air.
  • the combustion air mixing chamber 39 is integrated into the blower 3.
  • an exhaust gas-combustion air mixture is supplied to the fuel mixing chamber 51 by the fan 3 via the supply air duct 54, which reaches the distributor plate 53 flows over the surface and mixes with the hydrogen flowing through the distributor plate 53 before it is ignited by an ignition electrode 13 arranged in the fuel mixing chamber 51.
