Definitions
- the invention relates to a control device according to the preamble of Claim 1.
- Air ratio the ratio of the amount of air to the amount of fuel
- lambda the ratio of the amount of air to the amount of fuel
- Air ratio the ratio of the amount of air to the amount of fuel
- Lambda slightly above the stoichiometric value 1, for example 1.3.
- Air-controlled burners unlike controlled burners, react to external conditions Influences that change the combustion.
- the combustion be readjusted after a change in the type of fuel or air density. she have a higher efficiency, thus higher efficiency as well as lower Pollutant and soot emissions.
- the environmental impact is lower, the lifetime will be extended.
- Control of the air ratio is particularly effective when using a sensor quality combustion can be observed.
- Typical are in known burners Oxygen sensors in the exhaust duct, temperature sensors on the burner surface or UV sensors used in the combustion chamber. Newer developments are based on the ionization electrode, which has long been standard for monitoring the Flame is used in burners.
- Air-controlled burners using an ionization electrode as a flame sensor are known from DE-PS 196 18 573. Such burners check the control loop among other things, that the measuring signal a safety margin around the Control setpoint during normal operation should not leave in the long term. Meets this Nevertheless, the burner switches off.
- the tax period should be as short as possible, since external influences during this Time can not be corrected.
- the quality of the control should be below monitored at least marginally and for plausibility become. If the position of the fuel valve or the air blower during the Control period is not monitored by additional measures, so can at a Defective the permissible emission levels are greatly exceeded.
- the invention is based on the object of quality control during such Control periods are inexpensive and easy to improve.
- 1 indicates the flame of an air-operated gas burner.
- a Ionization electrode 2 protrudes into the area of the flame 1.
- the flame 1 is from an adjustable air blower 3 and an adjustable gas valve 4 fed.
- One Safety valve 5 in the gas supply ensures a faultless shutdown in case of a Error message.
- a control device 6 the air blower 3, the gas valve 4 and the Safety valve 5 as follows.
- the actuator of the air blower 3 is by means of a power request signal. 7 driven to a speed corresponding to a speed signal 8, as Input parameter is used for the performance request.
- z. B the measurement signal of a Differential pressure gauge in the ventilation duct, to be used as a power variable.
- the adjustable gas valve 4 is not shown by a control signal 9 via a Motor driven. An unshown mechanical pressure regulator is interposed.
- the safety valve 5 is opened against spring pressure, as long as an enable signal 10th is applied.
- the air ratio is controlled by the ionization electrode 2.
- the Tuning of the control signal 9 to the speed signal 8 is done by observation of current and voltage at the ionization electrode 2 as a measure of flame quality.
- the speed signal 8 is passed through a filter 11 to a control unit 12, which is realized as a program part in a microprocessor.
- a control unit 12 which is realized as a program part in a microprocessor.
- the control signals 13, 14 be fed to a controller 15, where they on the basis of flame quality in one Adjusting module 16 are weighted and added to form the control signal 9.
- Controller 15 is implemented as a program part in a microprocessor.
- a sensor evaluator 17 prepares two signals.
- a sensor signal 18 is a measure of the quality of the flame 1.
- a monitoring signal 19 indicates Extinguish the flame 1 a monitoring unit 20 in the controller 15 on.
- the monitoring unit 20 interrupts a corresponding monitoring signal 19 towards the release signal 10 and thereby closes the safety valve 5. Thus hears the gas supply on.
- the sensor signal 18 is supplied to the controller 15. There it becomes first by means of a low-pass filter 21 smoothed to suppress glitches and flicker.
- a comparison unit 22 is a generated by the control unit 12 and via a Correction unit 23 subtracted nominal reference signal 24.
- the setpoint signal 24 represents over a characteristic curve at each speed a desired size of the Sensor signal 18. From the difference is from a proportional controller 25 and a parallel integration unit 26 of the internal control value x redetermined, the two Control signals 13 and 14 re-weighted and thus changed the control signal 9.
- control value x of course by other types of controllers, for example a PID controller or state controller.
- the sensor signal 18 is thus in its normal operation on his current performance associated setpoint and the combustion receives the above the setpoint signal 24th set quality.
- the air ratio is programmed during a starting process controlled until the burner and the ionization 2 their operating temperature approximated or reached. Only then follows the normal operation, in which the Air ratio is regulated.
- the reason for the control at the start is, among other things, the inertia of the sensor, which measures the quality of combustion.
- ionization electrodes not only ionization electrodes have such a delay.
- an ionization signal can only be used for regulation about 30 s after ignition.
- Other sensors, such as ZrO 2 oxygen sensors in the exhaust duct, require more than one minute, depending on the design, until reliable control signals can be obtained.
- the control unit 12 During a startup process, the control unit 12 generates a start-up signal 27, which is supplied to the controller 15 and causes it to be linear in time to generate increasing actuating signal 9.
- a switching unit 28 selects as long as that Start-up signal 27, instead of the control value x, off. Because the air blower 3 meanwhile produces a constant flow of air, the air ratio of initially large Values are getting smaller and smaller. Once the mixture of air and gas is enough fat, can an ignition of the flame 1 done.
- the controller 15 opens the safety valve 5 by means of the release signal 10 and generates an actuating signal 9 which sets the position of the gas valve 4 to its start position S 1 .
- the control unit 12 introduces the controller 15. Start-up signal 27 too.
- the start-up signal 27 determines in this phase a control value x 'as a provisional replacement for the control value x in the weighting of the two control signals 13 and 14. Their size is fixed at the above-mentioned firing speed of the air blower 3.
- the controller 15 weights the control signals 13 and 14 on the basis of the start-up signal 27, so that a control signal 9 corresponding to the starting position S 1 appears at the output of the controller.
- control signal 9 after a programmed sequence, wherein the amount of gas per unit time is increased linearly.
- the gas-air mixture is initially very lean and is getting fatter during the ignition, until the time T 2 is an ignition.
- the linear increase of the actuating signal 9 is stopped and the position of the gas valve 4 is kept constant at its ignition position S 2 .
- the control unit 12 can then estimate the gas range based on the ignition position S 2 and the required ignition time T 2 -T 1 and selects the control value x 'new so that it matches the estimated gas range.
- the new control value x ' is, depending on the type of gas, z. At 0.9 or 0.1. This leads to a renewal of the gas valve 4 to a correction position S 3rd
- the actuating signal 9 in FIG. 2 is therefore quickly corrected to the correction position S 3 at the time T 3 .
- control value x 6 for the control phase after ignition would be specified as the programmed value or determined as the learned value from the last decommissioning and stored.
- FIG. 2 also shows a dot-dashed curve representing the actuating signal 9, if it is calculated on the basis of the sensor signal 18. This fictitious actuating signal S E would thus be the actuating signal 9 if the control loop is not broken during a starting process.
- the monitoring unit 20 must naturally means of an analog circuit or a part of the program the behavior of the flame in response to the fictional setting signal simulate s E an outdoorsrend and the fictional setting signal s Set E to be that the current measured value of the resulting ionization signal 18th
- the fictitious control signal s E is not suitable for this reason in this phase, in order to enable a control. Nevertheless, it has been shown that the fictitious actuating signal s E comes so quickly, for example already 2 seconds after the opening of the gas valve 4, so close to the value which is optimally regulated later that it forms a reliable comparison means, in order to prevent serious errors from harmless Inaccuracies of the control to distinguish.
- the monitoring unit 20 continuously checks whether the fictitious actuating signal s E or the associated control value x E lies within a limit range around the actual actuating signal 9.
- the boundaries are designated S 3min and S 3max in FIG. 2 and have, for example, the values of 0.90 times S 3 and 1.25 times S 3 .
- the monitoring unit 20 checks the otherwise unused control value x by comparing it with the control value x '. This comparison is equivalent to a comparison between the fictitious actuating signal s E and the control signal (9). The difference is only the previous or the subsequent processing by the control module 16.
- the monitoring unit 20 As soon as the fictitious actuating signal s E leaves said boundary region, the monitoring unit 20 generates a fault signal (not shown) and switches off the release signal 10 so that the safety valve 5 is closed.
- the controller 6 stores the detection of a disturbance signal in one EEPROM to allow the event after any failure of the supply current is recognizable again.
- An unillustrated unlocking signal through the Burner operator can override the consequences of an earlier fault signal.
- the monitoring unit 20 switches off the combustion only when the fictitious actuating signal s E has left the boundary area for a predetermined time.
- monitoring need not necessarily be continuous, but could also be discrete at one or more specified times.
- the generation of the actuating signal 9 is taken over by the processing of the sensor signal 18.
- the control signal 9 quickly adjusts to its control value S 4 .
- the power of the burner during the control period to a other value within the entire permissible range.
- FIG. 1 also shows that the monitoring unit 20 alternatively the Ionisationssignal 18 instead of the control signal 9 or the control value x processed.
- the monitoring unit 20 is compared with its setpoint signal 24 and may, for example, a preprogrammed limit range, which may also be time-dependent, do not leave.
- a sole application of this alternative would be a very simple Ausgestalltung enable the monitoring unit 20.
- a comparison signal is already in shape the setpoint signal 24 is present and the comparison is already by the Comparison unit 22 in the form of the difference signal 35 of the monitoring unit 20th fed.
- monitoring begins.
- the monitoring unit 20 checks permanently or at discrete points in time whether the ionization signal I E does not leave its limit values, which are drawn as I SOLLmin and I SOLLmax .
- control process begins on the basis of the ionisation signal 18.
