Definitions
- the invention relates to a gas burner device according to the preamble of patent claim 1 and a method for operating a gas burner device according to the preamble of patent claim 8 .
- a gas burner device of the type mentioned at the outset is known from document US 2016/0146455 A1.
- This consists of a conveying device for conveying a gaseous fuel to a burner and a recirculation device for returning an amount of exhaust gas produced during combustion of the fuel to the burner.
- a gaseous fuel is conveyed to a burner with a conveying device and an amount of waste gas produced during combustion of the fuel is fed back to the burner with a recirculation device.
- a valve (see reference numerals 128 and 228 there) is provided on the recirculation device for adjusting the said amount of exhaust gas.
- the object of the invention is to improve a gas burner device of the type mentioned at the outset and a method for operating such a gas burner device.
- a gas burner device that can be used more universally with regard to the gaseous fuel used and a more universal method for its operation are to be created 30 .
- This object is achieved with a gas burner device of the type mentioned by the features listed in the characterizing part of patent claim 1 .
- this object is achieved with a method for operating such a gas burner device by the features listed in the characterizing part of patent claim 5 .
- a sensor device for determining a composition of the fuel is therefore provided according to the invention, the recirculation device being designed to be controlled as a function of the composition of the fuel detected by the sensor device.
- a composition of the fuel is determined using a sensor device and the recirculation device is controlled as a function of the composition of the fuel detected by the sensor device.
- controlled used in the present context for the sake of simplicity includes the two terms “control” and “regulate” that are common in control technology.
- the gas burner device according to the invention or the method according to the invention for operating such a gas burner device is characterized in that the exhaust gas quantity recirculated to the burner is determined based on the composition of the fuel.
- the result of this is that with a single burner, for example natural gas as well as 30
- a sensor device for determining the composition of the fuel or that "a composition of the fuel is determined using a sensor device” means very generally that the sensor device is suitable for draw conclusions about the composition of the fuel either directly or indirectly.
- the sensor device can thus, as will be discussed in more detail below, for example as a gas chromatograph, but also as a temperature sensor for detecting the focal surface temperature. It is also possible, for example, that a sensor device that measures UV light is used to detect the so-called OH and/or CH bands, which result as an intermediate product during combustion and from which the composition of the fuel can be deduced can , capture .
- the sensor device can be designed very differently; Ultimately, it is a question of using them to or can determine the composition of the fuel used in order to determine the amount of exhaust gas that is actually to be returned for clean combustion on this basis.
- Patent specification DE 39 38 090 CI also discloses a burner device with a conveyor device and a recirculation device.
- the two impellers also sit on a common drive shaft and can therefore not be operated independently of one another.
- Document FR 2 711 224 A1 also discloses a burner device in which the conveying device and the recirculation device are firmly connected to one another.
- Patent specification DE 693 12 226 T2 discloses a boiler with two flue gas paths.
- a burner for the combustion of hydrogen is known from the document WO 1995/023315 A1, in which, however, only local recirculation in the area of the individual flame tongues (flame recirculation) is provided.
- FIG. 1 shows the gas burner device according to the invention with a sensor device arranged in front of the fuel-air mixing device, seen in the direction of flow of the fuel.
- the gas burner device shown in the figure consists in a known manner first of a conveying device 1 for conveying a gaseous fuel to a burner 2 and a recirculation device 3 for returning an amount of exhaust gas produced during combustion of the fuel to the burner 2 .
- the conveying device 1 preferably comprises a blower.
- a method for operating a gas burner device in which 10 a gaseous fuel is conveyed to a burner 2 with a conveying device 1 and an amount of exhaust gas produced during combustion of the fuel is returned to the burner 2 with a recirculation device 3 .
- a sensor device 4 is provided for determining a composition of the fuel and that the recirculation device 3 is designed to be controlled 20 as a function of the composition of the fuel detected by the sensor device 4 .
- a composition of the fuel is determined with a sensor device 4 and the recirculation device 3 is controlled as a function of the composition of the fuel detected by the sensor device 4 .
- the sensor device 4 can be used either as a gas chromatograph, 30 as a gas thermal conductivity sensor, as an ionization sensor, as a UV sensor, as an oxygen sensor and / or as a temperature sensor (especially flame temperature sensor) is formed.
- the gas chromatograph and the gas thermal conductivity sensor are seen in the flow direction of the fuel before 5 (i.e. in the area before combustion) and the ionization sensor, the UV sensor, the oxygen sensor and/or the temperature sensor after or on the burner 2 ( i.e. in the area of combustion).
- the only figure shows schematically the option of a gas chromatograph or a gas thermal conductivity sensor on the fuel supply line. The other options are not shown separately because they can be imagined without further ado.
- each sensor device 4 is suitable for determining the composition of the fuel used.
- the aforementioned control device 6 is connected in terms of data technology, as shown in the single figure by a dotted line, optionally with the conveyor device 1, the sensor device 4 and/or (as just explained) with the recirculation device 3 or the (preferably electrically actuatable) Recirculation valve 3.1 connected formed.
- the delivery device 1 and the recirculation device 3 are preferably each controlled individually depending on the composition of the fuel (preferably by the control device 6).
- a fuel/air mixing device 5 is arranged in front of the burner 2, as seen in the flow direction of the fuel, preferably, as shown, in front of the conveyor device 1, 30. Or in other words: one for mixing the gaseous fuel
- the fuel-air mixing device 5 provided with air is preferably controlled by the control device 6 as a function of the composition of the gaseous fuel. It is further preferably provided that in addition to a fuel 5.1 and an air supply connection 5.2 5, it has an exhaust gas supply connection 5.3 connected to the recirculation device 3.
- the burner 2 (for example - as shown schematically - a cylinder burner) 10 is arranged in a combustion chamber 2.1 with an exhaust gas discharge connection 2.2 and the recirculation device 3 has an exhaust gas connection 3.2 connected to the exhaust gas discharge connection 2.2.
- the exhaust gas connection 3.2 of the recirculation device 3 is preferably connected to the exhaust gas supply connection 5.3 of the fuel/air mixing device 5 via a connecting line 3.3.
