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 present invention is based on the problem of a to provide improved control method for gas burners. According to the invention Problem solved by a control method with the features of claim 1.
- 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 gear ratio.
- the combustion process in the Burner monitors.
- Information about the. Can be obtained from the ionization signal Combustion process and thus be obtained on the existing gas quality.
- the Ionization signal is only in an area near a burner full load operation to set the gear ratio depending on the 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. Outside the above range the gas / air mixture regulated depending on the previously determined transmission ratio.
- Burner gear ratio with in particular 70% to 100% of the burner at full load driven and during this operation with the help of an ionization signal a transmission ratio taking into account the existing gas quality is determined. As soon as the working state of the burner ranges in particular from 70% to 100% of the burner at full load leaves, the gas / air mixture while maintaining the last certain transmission ratio regulated.
- a reference slew rate for the Ionization signal determined.
- This reference slew rate is for a burner with predetermined burner conditions, in particular at a predetermined temperature and Burner downtime, determined and saved.
- the current rate of rise of the ionization signal measured, namely when the Burner when starting due to a heat request the predetermined Has burner conditions.
- This measured rate of increase is measured with the Reference slew rate compared, and then when the measured Slew rate from the reference slew rate by a predetermined one Dimension deviates, a new gear ratio is set.
- the burner operated in the vicinity of a burner at full load. Should it not be possible to To operate the burner in the vicinity of the burner at full load, an alternative can also be used Maintenance indicator can be activated to show an operator the change.
- the above method can still be improved may have a burner reference start defined from certain burner conditions.
- the scheme states that the burner will not for a predetermined period of time was operated - so-called downtime - and all temperatures - e.g. Water temperatures of a boiler to be operated by the burner - below one specified value, the burner should first be on for a specified period of time a predetermined value of burner full load operation, e.g. 75% of the burner at full load, operated before regulated depending on the heat requirement becomes.
- the invention relates to a control method for gas burners for providing a Gas / air mixture.
- the rate of increase of the Ionization signal measured.
- This measured rate of increase is measured with a Reference slew rate for the ionization signal compared, and then when the measured slew rate from the reference slew rate by one a predetermined dimension deviates, a new gear ratio is set.
