Description

Method for operating a gas burner
Technical Field
The invention relates to a method for operating a gas burner, wherein a voltage signal of a voltage applied to an ionizing electrode arranged on the gas burner is monitored, wherein the voltage on the ionizing electrode is regulated to a target value.
Background
A method for operating a gas burner of the type mentioned at the outset is known from DE 10 2015 222 A1. There, the voltage at the ionization electrode of the gas burner is regulated to a desired value in order to compensate for the leakage current.
Disclosure of Invention
The invention is based on the object of improving a method of the type mentioned at the beginning. In particular, a method for operating a gas burner is to be provided, by means of which condensate blockages in the gas burner can be detected and which can thus make the operation of the gas burner safer.
This object is achieved by a method for operating a gas burner of the type mentioned at the outset in that: when a first deviation of the voltage signal from the setpoint value reaches a first predetermined magnitude, the voltage signal is continuously measured for a predetermined time interval, and a fault message is generated if a second deviation of the voltage signal reaches a second predetermined magnitude is detected from the voltage profile in this time interval.
In other words, the solution according to the invention is therefore distinguished in that a fault message is generated when two deviations of the voltage signal of the ionization electrode, which otherwise remain constant, of a certain height are detected within a certain time interval, since the occurrence of these deviations is attributed to condensate blockages in the gas burner.
Further advantageous embodiments of the method according to the invention are described below in the description of the figures.
Drawings
In the following, the method according to the invention for operating a gas burner together with advantageous further developments thereof are explained in more detail in general terms and also in accordance with the drawings of preferred embodiments.
It shows
Fig. 1 schematically illustrates a method according to the invention according to a preferred embodiment.
Detailed Description
In the method according to the invention for operating a gas burner, a voltage signal S of a voltage applied to an ionizing electrode arranged on the gas burner is monitored, wherein the voltage on the ionizing electrode is set to a target value S 0 。
It is now important for the method according to the invention for operating a gas burner that the voltage signal S is equal to the setpoint value S 0 By a first predetermined magnitude deltas 1 The voltage signal S is continuously measured over a defined time interval Δ t, and if a second deviation of the voltage signal S is detected by a second predetermined magnitude Δ S on the basis of the voltage profile within this time interval Δ t 2 Then fault information is generated.
It is also preferred that the gas burner is switched off if a fault message has been generated. It is also preferred that after a shutdown as a result of the generated fault information, the gas burner can only be operated again after receiving safety information on the gas burner. It is also preferred that the gas burner is automatically forced after switching off. In addition, it is particularly preferred to lock the gas burner after the fault information has been generated, so that a layperson cannot operate the gas burner again. The safety information is preferably a specific code which is only known to the professional (i.e. for example the respectively trained heating installation worker) and which is input on an operating field on the housing of the gas burner, alternatively an electrical signal which is generated by rotating a specific key in a receptacle provided for this purpose in the housing of the gas burner, or alternatively an electronic signal which is received by the gas burner and is transmitted by the professional to the gas burner via the internet or by radio. In principle, other methods for generating security information known to the person skilled in the art can also be used here. This treatment is used to protect the user of the gas burner. If too much condensate accumulates in the gas burner, this can affect the combustion process and lead to the production of health-damaging amounts of carbon monoxide. The user of the gas burner is protected from carbon monoxide by locking the burner until the burner is inspected, repaired if necessary and reopened by a professional.
It is also preferred if the voltage signal S and the setpoint value S are not detected 0 By a first predetermined magnitude deltas 1 The method is started again from the beginning or the measurement of the voltage signal S is simply continued. It is also preferred if during a certain time interval Δ t no voltage signal S is detected from the setpoint value S 0 By a predetermined second magnitude Δ S 2 The gas burner remains operational. It is also preferred if during a certain time interval Δ t no voltage signal S is detected from the setpoint value S 0 By a predetermined second magnitude as 2 The method is started again from the beginning. If no voltage signal S is detected during a determined time interval Δ t 0 By a predetermined second magnitude Δ S 2 There may also be no condensate plugging, i.e. the operation of the combustor need not be limited.
Furthermore, it is preferred that the pairs are implemented by a computing unitProcessing of the measurement data of the voltage signal S. It is additionally preferred that the voltage signal S is at a nominal value S 0 Is determined in advance of a first deviation of a first magnitude as 1 Greater than the rated value S 0 1% and/or the voltage signal S and the setpoint value S 0 Of a predetermined second magnitude as of a second deviation of 2 Greater than the rated value S 0 1% of the total.
Finally, it is preferred that the length of the determined time interval Δ t is 20 to 200 seconds.
As is clear from the above description, the method according to the invention for operating a gas burner leads to a significantly safer operation of such a burner, since condensate blockages can be quickly identified, and therefore damage to the health of the user of the gas burner can be effectively prevented.
