Definitions
- the invention relates to a dark radiator with a burner, a fan and a radiant tube, 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 emit a flame into the radiant tube.
- infrared heaters are often used to heat production and storage facilities.
- Dark radiators have one or more radiant tubes as radiant elements, to which at least one burner is assigned.
- Combustion of a mixture of combustible gas and air within the burner generates a flame that can be distributed over the entire length of the radiant tube using a fan.
- Natural gas or liquid gas is used as fuel gas, which is mixed in a mixing chamber in a specified ratio, after which it is fed into the combustion chamber via a nozzle and ignited.
- the fuel-air mixture is guided through a grid or mesh, which also has the task of holding the flame.
- the radiant tubes are regularly connected to the burner in a linear or U-shaped manner and should radiate the heat generated by the flame evenly over the entire length of the tube.
- the radiant tube is evenly heated by the flame and generates thermal radiation, which is radiated onto an area to be heated. Reflectors are often used to increase efficiency.
- the exhaust gases resulting from the combustion are removed from the radiant tube with the help of the blower, for example discharged to the outside air via exhaust pipes.
- DE 10 2014 019 765 A1 proposes blowers and To control gas valve by means of a control device to ensure complete combustion of the mixture of fuel gas and air.
- EP 2 708 814 A1 also proposes equipping the burner with a mixer and at least one secondary air duct, with the burner being set up so that part of the air supplied by the blower is supplied to the mixer and another part of the air is supplied to a secondary air duct , to direct part of the supplied combustion air to the flame without fuel.
- DE 10 2014 019 766 A1 also proposes using a sensor to detect the current mixing ratio and/or the type of gas, in particular with regard to the admixture of other types of gas, and to supply gas and/or air to the burner depending on the comparison result between measured and to the necessary mixing ratio until the necessary mixing ratio is established.
- the above solutions have proven themselves in practice, as a result of which dark radiators today have relatively low pollutant emissions while at the same time being highly efficient.
- the object of the present invention is to provide a dark radiator whose pollutant emissions are further reduced with at least the same level of efficiency. According to the invention, this object is solved by the features of the characterizing part of patent claim 1.
- a dark radiator which has an efficiency that is at least the same as in the prior art and in which the emission of pollutants is reduced. Due to the fact that 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 blower is connected to an ejector whose suction connection is connected to the hydrogen supply, with the combustion air sucked in by the blower serving as the driving medium, so that the blower supplies the burner with a hydrogen combustion air mixture is supplied.
- This enables the supply of a hydrogen/combustion air mixture in a defined mixing ratio, whereby the flame temperature can be adjusted.
- the flame temperature can be reduced. Due to the high reactivity of hydrogen, a high air ratio of 2.5 to 3 is possible. In this way, the flame temperature can be brought below the limit temperatures of nitrogen oxide formation and the materials of the radiant tube.
- the burner comprises a gas nozzle and a mixing tube, which is fed with hydrogen from the gas nozzle, the mixing tube being flushed with combustion air by the blower, the gas nozzle forming an ejector with the mixing tube, the driving medium of the ejector hydrogen introduced through the gas nozzle and the medium sucked into the mixing tube is combustion air located in the jet tube and an ignition device for igniting the hydrogen-combustion air mixture is connected downstream in the flame direction at a distance from the mixing tube.
- a non-return lock is preferably arranged in the mixing tube at its end directed in the direction of the flame. This prevents flashback into the mixing tube.
- the burner comprises a gas nozzle, the blower being set up for flushing the gas nozzle with combustion air and no combustion gas mixing chamber for premixing combustion gas and combustion air being arranged and the gas nozzle being fed exclusively with combustion gas.
- the blower being set up for flushing the gas nozzle with combustion air and no combustion gas mixing chamber for premixing combustion gas and combustion air being arranged and the gas nozzle being fed exclusively with combustion gas.
- a combustion air mixing chamber is arranged upstream of the burner in the flame direction and is connected to a combustion air source and the exhaust gas discharge line.
- the fan is arranged upstream of the burner in the flame direction and the combustion air mixing chamber is arranged inside the fan. This achieves good mixing of combustion air and exhaust gas within the fan.
- the connection between the exhaust gas discharge line and the combustion air mixing chamber includes a branching device, by which the ratio of the branched off exhaust gas volume flow to the combustion air volume flow is determined. This allows the oxygen content of the combustion air/exhaust gas mixture to be adjusted.
- the branching device preferably includes an adjusting device, by means of which the ratio of the branched off exhaust gas volume flow to the combustion air volume flow can be adjusted.
- the burner serves as a primary burner, which is followed by a secondary burner at a distance in the flame direction in the radiant tube, the fuel gas supply of which is connected to a hydrogen source as the fuel gas source, with the exhaust gas stream of the upstream primary burner being supplied to the secondary burner as combustion air.
- a secondary burner at a distance in the flame direction in the radiant tube, the fuel gas supply of which is connected to a hydrogen source as the fuel gas source, with the exhaust gas stream of the upstream primary burner being supplied to the secondary burner as combustion air.
- a compensating element in the form of a compensator is interposed between the primary burner and the secondary burner to compensate for thermally induced changes in length within the radiant tube.
- This compensator which is preferably designed as an axial compensator, absorbs the movement of the jet pipe along the axis, thereby avoiding damage to the jet pipe.
