- the signal processing device in particular the analog-to-digital converter (s), is integrated in the control, monitoring and monitoring unit 9.
- the value of the fuel supply 6 with which the actuator 5 is driven can be used as the value of the burner output. Since the fuel supply and the air flow (air supply) are related to one another via the predetermined air ratio ⁇ , the air supply can equally be regarded as a measure of the current performance of the combustion device. Thus, the rotational speed 11 is a representative value for the performance of the combustion device.
- the material of the ionization electrode 7 is often KANTHAL®, e.g. APM® or A-1®. Nikrothal® electrodes are also contemplated by those skilled in the art.
- the ionization signal 13 is generated.

- FIG. 2 shows the setpoint values 14 of the ionization flow for two different gas groups / families above the fan speed 11.
- the skilled artisan recognizes that instead of the fan speed 11, another equivalent size of the throughput of air can be applied.
- the ionization measured value 13 is regulated via the control loop comprising control unit 9, actuating signal 12, the gas ratio actuator 5 adjusting the mixing ratio, flame in the combustion chamber 2 and current through ionization electrode 7 to the desired value 14 of the ionization current.
- the air ratio ⁇ is set for each occurring value of the air throughput, that is to say for each fan speed 11.
- the ionization current desired value 14 is determined by setting the desired air ratio ⁇ as a function of the fan speed 11 via the gas quantity actuator 5 as an example and determining the subsequently measured value of the ionization current as the characteristic point of the characteristic curve 15, 16.
- further sensors are preferably used, with the aid of which the air ratio ⁇ can be measured.
- the skilled person is in particular the measurement of O 2 value and / or the CO 2 value in the exhaust gas known. In this case, the air ratio ⁇ can be determined directly from the measurement result.
- the characteristic curve 15, 16 determined in this way is representative of all combustion devices which have the same assignment of ionization flow 14 over the air throughput and at the same time of the air ratio ⁇ over the air flow.
- the assignment of the detected of the ionization current measured value 13 to the ionization current desired value 14 and the compensation of the detected ionization current measured value 13 to the desired value 14 thus represents a processing to an air-number measured value which is equivalent to a direct measurement, for example of the O 2 value in FIG Exhaust gas and a direct calculation of the associated Lucasiere-measured value, which is then corrected to a predetermined Gutiere setpoint.
- the characteristic curve 15 shows the course of the desired value, which can be used for a group of similar gas compositions.
- One example is the E-gas group, whose main component is methane gas.
- the characteristic curve 16 shows the course of the desired value, which can be used for a second group of similar gas compositions.
- Exemplary here is the B / P gas group with mixtures of propane with propene or propane and butane.
- Each gas group consists of gases, which in turn are mixed with the base gas and other gases. These are for example in the E-gas group mixtures of methane and propane, mixtures of methane and nitrogen or mixtures of methane and hydrogen. The mixtures represent real mixtures of gas sources for the incinerator.
- a characteristic of the fuel flow 12 over the air flow 11 is defined, wherein the air flow rate is selected as the measure of the burner output.
- the characteristic curve is represented by a position of a stepper motor over a fan speed. This results within the boundary mixtures characteristic bands of the fuel supply 12 on the air supply 11th That fact is in FIG. 3 illustrated.
- the characteristic curve 15 As setpoint characteristic FIG. 2 choose. If the gas supply actually delivers a gas from the e-gas group, then the characteristic point of the gas currently regulated for a power lies in the characteristic curve 17.
- the characteristic curve 16 should be selected (as setpoint characteristic). If the gas supply supplies a gas from the B / P gas group, the currently regulated characteristic point of the gas lies in the characteristic curve 18.
- the two gas groups E-gas and B / P-gas have a sufficient distance of the minimum air requirements L min for their respective gases to each other. Therefore, the characteristic bands overlap FIG. 3 Not. Consequently, a limit characteristic 19 between both characteristic bands can be defined.
- the limit characteristic curve 19 advantageously proceeds as an arithmetic mean between the upper and lower limits of the characteristic bands 18 and 17 FIG. 3 ,
- the regulated characteristic point for gases of the E-gas group is above the limit characteristic curve 19.
- the corrected characteristic point is below the limit characteristic curve 19 if the characteristic curve is selected correctly.
- the regulated characteristic point is not always in the characteristic band of the group of gases on the other side of the limit characteristic curve 19. However, the regulated characteristic point lies on the other side of the limit characteristic curve 19. Thus lies the regulated characteristic point in the case of a gas of the E-gas group with the wrong characteristic curve below the limit characteristic curve 19. For a gas from the B / P gas group, the regulated characteristic point lies above the limit characteristic curve 19. The position of the regulated characteristic point in With reference to the limit characteristic curve 19, it is therefore possible to detect the faulty selection of a characteristic curve for a fuel.
- the characteristic bands 17 and 18 overlap (partially). Such a situation is in FIG. 4 shown.
- at least 2 percent of the areas of the characteristic bands 17 and 18 overlap, at least 5 percent overlapping of the areas of the characteristic bands 17 and 18 is possible, and there are cases with at least 20 percent or at least 50 percent overlap of the areas of the characteristic bands 17 and 18th
- the characteristic bands 17 and 18 are close to each other. According to one embodiment, the overlaps occur in the lower 60% of the power range, according to a particular embodiment in the lower 40% or 10% of the power range.
- the limit characteristic 19 can be clearly defined between the characteristic bands. Also in this case, for example, the limit characteristic 19 can be defined as an arithmetic mean between the upper and lower limits of the characteristic bands 18 and 17.
- the limit characteristic 19 is then defined only by the maximum power (corresponding to the maximum air flow rate and / or the maximum fan speed) up to a defined limit 20.
- the defined limit 20 is above the power range in which the characteristic bands 17 and 18 overlap.
- the defined limit 20 is at least 5% of the maximum power, furthermore preferably at least 10% of the maximum power, also preferably at least 20% of the maximum power, above the first overlap (starting from the maximum power) between the characteristic belts 17 and 18.
- the limit 20 can also be (starting from the maximum power) the last overlap-free tabular value of the characteristic curve.
- the check as to whether the regulated characteristic point is on the right side of the limit characteristic 19 takes place only in the region between the limit 20 and the maximum power.
- the detection of a wrong set characteristic is therefore limited to the first hours of operation and / or to the first days of operation.
- the detection of an incorrectly set characteristic may be limited to the first 5 hours of operation and / or to the first 50 hours of operation and / or to the first 500 hours of operation.
- the person skilled in the art recognizes that the time limit for the detection of a wrong set characteristic can depend on the network (gas supply network). The time limit of the detection of a wrong set characteristic is advantageous, because it prevents false detection because of extreme environmental influences. Such extreme environmental influences are, for example, a cover of the exhaust path during the life of the burner device.
- the limit characteristic curve 19 can move into the bands 17 and / or 18. This case is in FIG. 5 shown. Due to the different Setpoint characteristic curves 15 and 16, one now obtains two limit characteristic curves 21 and 22. With correct operation with E-gas one finds oneself in the volume 17. Above the boundary characteristic 21 one surely has E gas as fuel gas 6. Below the limit characteristic 21 one has Fuel gas 6 either E-gas or B / P gas. In this case, it can not be detected below the limit characteristic 21 whether one has E gas or B / P gas as the fuel gas 6.
- the person skilled in the art recognizes that at least one of the two limit characteristic curves 21, 22 can also lie between the belts 17, 18. If one selects a gas group and is only one of the limit characteristic curves for the wrong gas group 21 or 22 within the band 17 or 18 assigned to the gas group, an operation with the wrong gas group can not be revealed across all tolerances and influences. The person skilled in the art also recognizes such in the event that both limit characteristics 21, 22 lie within the band 17 or 18, which is assigned to the respective gas group. This case is in FIG. 5 outlined.
- both limit characteristics 21, 22 are outside the respectively assigned band 17, 18, then a common limit characteristic can be obtained 19 are found, which completely fulfills the function of the two limit characteristics 21, 22.
- FIG. 6 is shown with which measure the increase of the A-value is achieved. If the position of the fuel valve 5 is adjusted so that it is above the limit characteristic curve 21, then the setpoint value of the ionization current over the entire power range is preset via the predetermined nominal value characteristic curve 15. This is possible because it is ensured above the limit characteristic curve 21 that only E gas is present as fuel gas 6 in the supply line. If the limit characteristic curve 21 is undershot, B / P gas could also be present as fuel gas 6 in the supply line. In this case, a setpoint characteristic 23 is specified, which adjusts the device to a larger A value. This ensures that even in the case of B / P gas as fuel gas 6 in the supply line no critical emissions can occur.
- the person skilled in the art recognizes that the lowering of the nominal value characteristic curve to the characteristic curve 23 is only carried out where critical emissions can also occur. This is determined by experiments with the wrong gas group for a selected characteristic 15. The A-lowering is then carried out from an air flow point 24 corresponding to the associated burner power point, from the B / P gas as the fuel gas 6 critical emissions occur.
- the characteristic 23 may be defined as a straight line, which is defined by its end point and the point 24. Thus, the characteristic 23 can be deposited easily (and without much memory) in the control, control and monitoring unit 9.
- the limit characteristic curve 19 and the limit characteristic curves 21, 22 are stored in the form of a table in the (non-volatile) memory of the regulating and / or control and / or monitoring device 9 according to one embodiment. Intermediate values between the points stored in the table are obtained, for example, by linear interpolation. Alternatively, intermediate values between the points defined by the table are interpolated by a polynomial over several adjacent values and / or over (cubic) splines. The person skilled in the art recognizes that other forms of interpolation can also be realized.
- the limit characteristic curve 19 or the limit characteristic curves 21, 22 is also calculated from other characteristic values from the characteristic curves, for example limit characteristics and / or reference characteristics of representative actuators under defined environmental conditions.
- the limit characteristic curve 19 can have a defined distance ratio to the two reference characteristics over the entire power range.
- the deposition of the boundary characteristics 19, 21, 22 is based on (sectionally defined) functions such as lines and / or polynomials.
