Definitions
- the invention relates to a control method for gas burners according to the preamble of Claim 1.
- Control procedures for gas burners are used to provide a gas / air mixture, that is, supplying a gas stream and a combustion air stream to a burner.
- the gas burner To inside the gas burner for optimal and complete combustion of the To provide fuel, namely the gas, the gas burner must be equipped accordingly coordinated gas / air mixture can be supplied.
- the ratio between the gas flow and the combustion air flow or the gas pressure and the combustion air pressure is called the gear ratio.
- the quality of the gas provided by the gas supply - the quality of Gas is defined by a so-called Wobbe index - fluctuates, has to Ensuring an optimal and complete combustion of the gas / air mixture in Depending on the quality of the gas can be varied accordingly.
- the ionization signal In the known control methods using an ionization signal for Gas burner, the ionization signal over the entire working area or Operating range of the burner to adapt the gas / air mixture to different Gas qualities used. At low burner operating loads this is However, the ionization signal is strongly dependent on external influences and therefore does not provide any reliable information about those actually in the burner Combustion conditions. State-of-the-art control procedures consequently to an unstable and therefore insufficient regulation.
- the present invention is based on the problem of a To provide improved control method for gas burners, according to the invention the problem by a regulatory procedure with the features of claim 1 solved.
- the control process for gas burners involves the provision of a gas / air mixture for a burner.
- the burner is a gas stream and a Combustion air flow supplied.
- the ratio between gas flow and Combustion air flow or the relationship between gas pressure and Combustion air pressure is called the transmission ratio.
- the ionization signal is only in an area nearby a burner full load operation for setting the gear ratio in Dependence on gas quality used.
- This range is preferably between 70% and 100% of the burner full load operation, but can also between 60% and 100% of Burner full load operation.
- the idea lies in this feature according to the invention based on the fact that the burner only during this working state or operating state Ionization signal provides a reliable statement about the combustion process.
- the gas quality is used to determine one taking into account the transmission ratio of the burner, in particular 70% to 100% of the burner is operated at full load and during this operation with the help of a Ionization signal taking into account the existing gas quality Gear ratio determined.
- the gas / air mixture regulated while maintaining the last determined transmission ratio. This ensures a particularly stable regulation.

Abstract
Description
Claims (2)
- Regelungsverfahren für Gasbrenner zur Bereitstellung eines Gas/Luft-Gemisches, nämlich zum Zuführen eines Gasstroms und eines Verbrennungsluftstroms zu einem Brenner, wobei ein Ionisationssignal eines Sensors verwendet wird um das Gas/Luft-Gemisch an unterschiedliche Gasqualitäten anzupassen, dadurch gekennzeichnet, daßa) das Ionisationssignal ausschließlich in einem Bereich in der Nähe eines Brenner-Vollastbetriebs zur Einstellung eines Übersetzugsverhältnisses verwendet wird,b) außerhalb des Bereichs des Brenner-Vollastbetriebs das Gas/Luft-Gemisch in Abhängigkeit dieses Übersetzugsverhältnisses geregelt wird,c) der Bereich des Verfahrensschritts a) zwischen 60% und 100% des Brenner-Vollastbetriebs liegt.
- Regelungsverfahren für Gasbrenner nach Anspruch 1, dadurch gekennzeichnet, daß das Ionisationssignal in einem Bereich von 70% bis 100% des Brenner-Vollastbetriebs zur Einstellung eines Übersetzugsverhältnisses verwendet wird.
