Definitions
- the invention relates to a method for stabilizing an operating behavior of a power-modulating, air-frequency-controlled gas fan burner for the consideration of disturbances in the combustion air path, fuel gas-air mixture path, Schugasweg and / or exhaust gas path according to the preamble of patent claim 1.
- the lower modulation limit means a burner operation at low load where the blower operates at a lower allowable fan speed. Lower speeds are not adjustable.
- the upper modulation limit means burner operation at full load where the blower operates at an upper allowable blower speed. Higher speeds are also not adjustable.
- a modulatable and / or switchable e.g. Variable speed fan via an airway to a combustion air amount L and doses a modulatable and / or switchable fuel gas control valve a fuel gas amount G.
- a mixing device combustion air and fuel gas are combined and processed into a homogeneous fuel gas-air mixture.
- the fuel gas-air mixture exits the burner is ignited and burns with heat.
- the resulting hot hot gases flow through a heat exchanger, transfer their heat to a heat transfer fluid and leave as cooled exhaust gases, the heater via an exhaust path in the area.
- An ionization electrode detects in the combustion zone an actual flame ionization signal I, which arises due to a voltage applied to a burner flame.
- a control device influences a supply of combustion air and / or fuel gas on the basis of operating data and / or target specifications.
- Possible exemplary causes of these disturbances are soiling of the air path with leaves, reducing the exhaust gas outlet cross section to the open due to icing or dead bird, deposits in the heat exchanger of corrosion products, defective air or exhaust pipes with leakage, wind suction, wind pressure, and so on.
- the ratio of fuel to combustion air is therefore of great importance for a trouble-free, but also for an efficient burner operation.
- the air ratio control is often based on a signal from the combustion, the so-called flame ionization signal.
- a suitable evaluation circuit makes use of the fact that flames conduct electricity when an electrical voltage is applied.
- independently adjustable devices for air and fuel gas delivery are required, so for example, a variable speed fan and an electronically adjustable gas valve - the gas valve is not pneumatically connected to the amount of combustion air, but receives its control signal from a device control.
- a number of correction factors are required which take into account the influences of the burner power dependency, the feasible fuel quantity and the burner design.
- burners with high power modulation ranges which can satisfy very different heat requirements, such as those arising from domestic heating at different outside temperatures or from hot water production for small and large dispensers.
- DE 199 36 696 A1 discloses a method with which an air-fuel ratio control in the lower part-load range is possible. Again, an ionization signal is generated in the flame and derived from the current air ratio, which is then compared with a predetermined air ratio and, if the current air ratio differs from the predetermined air ratio, the current air ratio is set to the value of the predetermined air ratio.
- the current air ratio is, however, determined at full load, since here is an area with a clear assignment between ionization signal and air ratio. In the partial load range of the burner is only controlled, ie unregulated operated.
- the relationship given in this characteristic ISOLL (Q) can be determined with simple means on the laboratory test bench for a given burner. More difficult is the regulatory implementation in practice at the end user, since the affected burner usually have no determination of the power Q (ie the fuel gas flow G).
- the object of the performance determination is solved by the relationship between the power Q and the amount of combustion air L, which can be represented as a fixed proportional relationship for a desired air ratio ASOLL.
- a characteristic ISOLL (L) Figure 3.
- the combustion air quantity L the direct measurement is not easy, can be expressed by the RPM (RPM, revolutions per minute) of the air-conveying blower, this is the Air quantity L usually directly proportional to the fan speed RPM.
- the blower speed can be measured by simple means.
- the characteristic ISOLL (L) becomes a characteristic Isoi i (RPM). In fact, the specified by a burner control flame ionization target signal is given as a function of the fan speed.
- the cited prior art has the disadvantage that an air-frequency-controlled burner operation with a wide power modulation range is very susceptible to interference with respect to changed flow resistances in the air, mixture, heating gas and exhaust gas path.
- the invention has for its object to provide a method for stabilizing the performance of a power modulating air-frequency-controlled gas blower burner, are compensated with the interference due to changes in flow resistance in the air, mixture, fuel gas and flue.
- a composition of a fuel gas-air mixture is adjusted as a function of a flame ionization actual signal and a nominal flame ionization signal by controlling the flame ionization actual signal to the nominal flame ionization signal and igniting the flame ionization.
- Target signal in response to a speed of an air-conveying blower is predetermined.
- Essential to the invention is at selected operating conditions of the gas fan burner and in deviation from the normal control mode, the fuel gas-air mixture temporarily and temporarily enriched with fuel gas and the flame ionization actual signal observed.
- a so-called flame ionization signal H is formed from the difference between a maximum flame ionization signal (stoichiometric combustion) observed during the enrichment and the flame ionization actual signal measured before the enrichment. Now, if this flame ionization signal H (short: signal swing) is smaller than a first tolerance amount T1 or greater than a second tolerance amount T2, a lower allowable fan speed associated with the lower modulation limit is increased. The burner control then returns to normal control mode.
- First (smaller) tolerance amount T1 and second (larger) tolerance amount T2 define an allowable flame ionization stroke interval ⁇ (FIG. 1 right).
- the flame ionization actual signal Prior to the enrichment of the fuel gas-air mixture with fuel gas engages the normal control operation, the flame ionization actual signal is due to the regulation equal to the desired signal.
- the temporary and short-term enrichment or enrichment of the fuel gas-air mixture causes a change in the flame ionization actual signal. If the starting mixture (before enrichment) is significantly lean of stoichiometry or lean, the ionization signal will rise significantly when enriched. If the starting mixture is only slightly more than stoichiometric, the ionization signal grows only slightly. On the other hand, if the starting mixture is stoichiometric or substoichiometric, the ionisation signal does not rise or even fall.
- the size of the ionization signal lift is determined by comparing the actual maximum flame ionization signal observed during enrichment with the original flame ionization actual signal prevailing before enrichment.
- the measured ionisation signals can be individual measured values or, in order to take appropriate account of statistically fluctuating measured values, average measured values (for example according to the principle of the moving average).
- the signal deviation is less than the first tolerance amount, then the original fuel gas / air mixture is diagnosed as too rich.
- the signal deviation is outside the permissible signal stroke interval. This is attributed to an increase in the flow resistance in the flow path (air, mixture, fuel gas and / or exhaust gas path).
- the signal swing is greater than the second tolerance amount, then the original fuel gas-air mixture is diagnosed as too lean.
- the signal deviation is outside the permissible signal stroke interval. This is attributed to a reduction in the flow resistance in the flow path (air, mixture, Schugas- and / or exhaust path).
- the burner control changes a parameter set on which the control is based by increasing the lower allowable fan speed. This corresponds to an increase in the associated lower modulation limit or an adaptation (restriction) of the power modulation range of the gas-jet burner to a flow resistance that is changed compared to a design state in the flow path.
- this adaptation operating points accessible to the burner control are limited to a higher power modulation range, operating points in the lower modulation range can no longer be approached.
- the formation of a fuel gas-air mixture having the desired composition at target air and thus a more stable performance of the gas fan burner is achieved because the burner flame neither rests on the outlet surface and overheats this, still lifts off the burner and tends to extinguish, nor excessive pollutant emissions causes. This results from the flatter characteristic I S OLL (L) at the higher power modulation range (FIG. 3), as described above.
- the control returns to the normal control mode.
- the original fuel gas / air mixture is thus diagnosed as "good.”
- the burner control system returns without intervention in one of the control mechanisms Parameter set returns to normal control mode.
- the steps of temporarily enriching the mixture for a short time with fuel gas, comparing the ionization signal stroke with the first amount of tolerance, and optionally increasing the lower allowable fan speed, may be repeated and progressively adjusting the power modulation range lead the gas fan burner.
- the lower permissible fan speed can be increased step by step and thus the power modulation accessible to the burner control system can be increasingly limited to higher ranges.
- the lower permissible fan speed can be lowered again, and thus the power modulation range accessible to the burner control unit can be expanded again.
- the repetition rate of repeated steps may be in minutes or hours.
- the frequency can also be selected as a function of the ionization signal stroke observed when enriching the fuel gas / air mixture; for smaller strokes, the frequency can be higher, for example, than for larger strokes.
- the steps described for checking and optionally adjusting the power modulation range of the gas-fired burner are carried out at selected operating states of the gas-fired burner and in deviation from the normal control operation, the fuel gas-air mixture.
- selected operating states may be, for example, operating points of medium and low power modulation, since, according to experience, the largest gradients of the ionization signal setpoint curve are present here.
- the steps can also be performed only at those operating points that are unchanged during a predetermined minimum period, so for example, after a five-minute burner operation at low load. When carrying out the steps, the burner operation must deviate from the normal control mode in order to enrich the mixture differently from the nominal air number.
- An embodiment of the method according to the invention is characterized in that the observed maximum flame ionization actual signal is a measured maximum flame ionization actual signal. This means that when enriching, the mixture composition is at least enriched to stoichiometry.
- the observed maximum flame ionization actual signal is an expected maximum flame ionization actual signal which can be derived from the observed time profile of the flame ionization actual signal in a forward-looking manner (time t).
- the expected course and the maximum can be calculated from the can be calculated predictively without actually reaching the stoichiometric operating point. This avoids any disadvantages with regard to burner overheating and pollutant formation, which is brought about by a stoichiometric operating point.
- the temporary enrichment of the fuel gas / air mixture with fuel gas includes enrichment and subsequent leaning to the original mixture composition prior to enrichment. According to one embodiment, this is done by a fuel gas supply of the gas fan burner dominant electronic gas valve at constant fan speed temporarily and briefly releases about 10% to 50% more fuel gas.
- the control of the gas valve is controlled and not in response to a current heat request.
- the activation of the gas valve and / or the enrichment of the mixture can take place in the manner of a jump function or a ramen function.
- the enrichment can be achieved by changing the fan speed and changing the amount of air at a constant amount of gas.
- the enrichment of the mixture takes place in another embodiment of the method by the flame ionization target signal influencing the composition of the fuel gas-air mixture is temporarily increased at constant fan speed by about 10% to 30%.
- the dependence of the nominal flame ionization signal on the speed of the fan is temporarily suspended.
- the increase of the desired signal in turn causes an opening of the gas valve and thus an enrichment of the mixture.
- a duration of the temporary, short-term enrichment of the fuel gas-air mixture with fuel gas is about 0.1 second to 10 seconds.
- the described adverse effects associated with the enrichment are very limited in time and therefore are not significant.
- the additional amount of heat released by combustion of the additional amount of gas is very low and can be easily absorbed and mitigated by the thermal storage capacity of the component masses involved.
- the increase in the lower allowable fan speed always takes place by a fixed, proportionate amount of about 5% to 30% of a currently available speed range.
- the amount of increase in the lower allowable fan speed depends on the Flammenionisationssignalhub when enrichment. This amount increases with increasing difference between Flammenionisationssignalhub and the respectively associated tolerance amount.
- a small distance of the flame ionization signal stroke from the first or second tolerance amount ie, a signal stroke lying only slightly outside the signal stroke interval
- a large distance of the flame ionization signal stroke from the first and second tolerance amounts ie, a signal swing far out of the signal stroke interval results in a large increase in the lower allowable fan speed.
- An embodiment of the method is characterized in that the first tolerance amount is about 10% to 30% of the nominal flame ionization signal, and that the second tolerance amount is about 30 to 50% of the nominal flame ionization signal.
- the exact values of the tolerance amounts also depend on the design, operating and / or installation conditions.
- An embodiment of the invention is characterized in that the increase in the lower allowable fan speed after each burner-off or after pressing a reset button or after a predetermined increase period is reset. Resetting to the design state means that the entire power modulation range is available again. Subsequent to the provision, the method according to the invention can then be carried out again. Already at the first or only at a repeated increase of the lower allowable fan speed, a warning message can be issued, which signals to a user or installer that there is a fault in the flow path.

- a permissible flame ionization stroke interval ⁇ which is limited by a first tolerance amount T1 and a second tolerance amount T2. If, in carrying out the method according to the invention, a flame ionization signal H of less than T1 or greater T2 is observed, the lower permissible fan speed is increased. The burner control then returns to normal control mode. On the other hand, if the signal deviation is within the permissible interval ⁇ , the burner control returns to normal control mode without a change in the fan speed.
- a modulation range of a power modulating burner is limited by a lower modulation limit (low load, QMIN) and an upper modulation limit (full load or rated power, Q NOM ).
- FIG. 3 schematically shows exemplary ionization signal profiles I at three different air ratios ⁇ as a function of a combustion air quantity L and illustrates the problem underlying this invention.
- the amount of combustion air L is the amount of air that is required to achieve a burner power Q at a given air ratio.
- a modulation range of a power modulating burner is limited by a lower modulation limit (minimum air flow, LMIN) and an upper modulation limit (maximum or nominal air flow, L NE NN).
- LMIN minimum air flow
- L NE NN maximum or nominal air flow
- the burner control is given an ionization curve with reference to the fan speed RPM (revolutions per minute) as the setpoint curve.
- RPM repetitions per minute
- the combustion air quantity L decreases for example along the paths AB and CD.
- the fan speed does not change or does not change significantly.
- the flame ionization setpoint curve is formulated as a function of the blower speed, the ionization setpoint does not change either. In the high modulation range, this reduction in the air volume has no significant effect on the air ratio of the fuel gas-air mixture, compare way AB.
