Definitions

  • the invention relates to a burner controller according to the preamble of claim 1.
  • Such burner controllers are part of devices for controlling the combustion in heat generating systems of small to medium power, which are operated with liquid fuels.
  • compound controllers in addition to such an automatic burner control, which regulate the material flow for fuel and air during operation following a commissioning process so that the combustion is optimized with regard to the combustion conditions, in particular with regard to emission behavior.
  • a compound controller is described in DE-C2-30 39 994 or in Patents Abstracts of Japan, Volume 13, No. 161 (M-815) 18/04/89; & JP-A-63-318 417.
  • a computer can be connected to such a compound controller, which replaces the microprocessor of the compound controller if the compound controller is to be adapted to the conditions of the incineration plant to be controlled when it is started up for the first time or when it is later adjusted. At least during commissioning, a probe that detects the exhaust gas state is used.
  • EP-A-124 330 describes a compound controller which can be switched between a "RUN” mode and a "commissioning" mode.
  • the microprocessor executes a calibration process, after which the operator of the heating system successively fills a target data memory with target data for various performance requirements.
  • automatic commissioning and automatic control while optimizing the target data during burner operation is not disclosed here.
  • the invention has for its object to provide a burner controller that is able to improve the emission behavior of a combustion system controlled by this burner controller, regardless of the characteristic of the actuators for air and fuel flow.
  • the single figure shows a diagram with a burner controller 1 according to the invention, to which a blower drive 2 of a blower 3 and a fuel pump drive 4 of a fuel pump 5 are connected.
  • the fan drive 2 is connected to the burner controller 1 via a first interface 6, this interface 6 in turn consisting of an operating voltage connection 6b, a control connection 6s and a feedback connection 6r.
  • the fuel pump drive 4 is connected to the burner controller 1 via a second interface 7, which consists of an operating voltage connection 7b, a control connection 7s and a Feedback connection 7r exists.
  • the fan drive 2 is advantageously a speed-controllable motor, for example a DC motor.
  • the drive energy is made available to him via the operating voltage connection 6b.
  • the speed control takes place via the control connection 6s.
  • the speed control is advantageously carried out by pulse width modulation.
  • the corresponding control electronics are part of the motor to be considered as a unit.
  • the feedback of the speed takes place via the feedback connection 6r.
  • the feedback signal advantageously provides a Hall probe, which, together with its signal conditioning circuit, is also part of the motor representing a structural unit. Such units are commercially available. It is essential that the feedback signal is a sequence of pulses of constant length and constant amplitude proportional to the speed of the motor, so that the length of the pause between the individual pulses is speed-dependent.
  • the fuel pump drive 4 is also advantageously a speed-controllable motor which can be controlled analogously to the blower drive 2 and whose feedback is also designed accordingly.
  • the fan drive 2 and fuel pump drive 4 can be, for example, EBM motors of the type M3G055-BD03-XA, VDB (32-38 V) DC, but are of course not restricted to this.
  • EBM motors of the type M3G055-BD03-XA, VDB (32-38 V) DC, but are of course not restricted to this.
  • the use of the same motor for both drives has advantages in terms of storage, spare parts availability and price.
  • the burner controller 1 also has connection points for a fuel preheater 8, for a fuel valve 9, for an ignition device 10 and for a flame monitoring device 11. In addition, it has a connection 12 for the operating voltage, usually for 230 V / 50 Hz and / or 110 V / 60 Hz.
  • Such a burner controller 1 is usually controlled by a heating controller.
  • a control input 13 which advantageously consists of three individual input points: a first input point 13.1 for a general switch-on command, a second input point 13.2 for a command to switch on a possibly existing second burner stage and a third input point 13.m for a power request signal in the case of a modulating burner.
  • the control input 13 consists of these three input points, the burner controller 1 can be used universally for all existing burner types "one-stage", "two-stage” and "modulating". This is useful in view of a low-volume series production, through which the manufacturing costs can be reduced.
  • the burner controller 1 automatically detects which of the input points are wired before starting up as part of a self-test. He can then configure himself or, if the configuration has been specified, can automatically detect whether the control paths are still operational.
  • a safety temperature limiter 14 Connectable to the burner controller 1 is also a safety temperature limiter 14, the contact of which must be included in the safety chain of the burner controller 1 in order to prevent the burner from being switched on under all circumstances, although the heat generator must be switched off due to overheating.
  • the burner regulator 1 contains a connection 12 connected power supply 15, which generates all required voltages.
  • the power supply unit 15 supplies the operating voltage to the operating voltage connections 6b and 7b, moreover via a fuel preheater relay 16 to the fuel preheater 8 and via said safety temperature limiter 14 and a protective relay 17 on the one hand via a fuel valve relay 18 to the fuel valve 9 and on the other hand via an ignition relay 19 to the Ignition device 10.
  • the four relays 16, 17, 18 and 19 are controlled by a programmer 20, which is indicated by dotted lines.
  • the programmer 20 is, for example, a microprocessor with associated peripheral interfaces and components.
  • the programmer 20 also has an input which is connected to a flame amplifier 21 which amplifies the signal of the flame monitoring device 11 and forms it into a signal which is compatible with the programmer 20.
  • Outputs of the program generator 20 are connected to the two control connections 6s and 7s.
  • the programmer 20 is also connected according to the invention to a setpoint data memory 22, in which setpoints for the speeds of the blower drive 2 and the fuel pump drive 4 are created.
  • Setpoint data memory 22 and actual data memory 23 are connected to a comparator 24, which in turn reports the results of comparison operations to programmer 20, for which purpose a corresponding connection is present.
  • the burner controller 1 has a further interface 25 for connecting an exhaust gas probe 26, which can be an oxygen probe, for example.
  • the interface 25 is connected to a setpoint generator 27, which is connected to the setpoint data memory 22.
  • This setpoint generator 27 is controlled by an operating mode switch 28, which is also connected to the programmer 20.
  • the operating mode switch 28 has two positions: a first position, the "SET" position, in which the setpoint generator 27 is activated, and a second position, the "RUN" position, in the programmer 20 processes its normal program.
  • the burner controller 1 thus has elements 25, 27 and 28 with which it is able to autonomously determine the data necessary for optimal operation of the combustion system when an exhaust gas probe 26 is connected.
  • the setpoint generator and possibly also the operating mode switch 28 do not represent separate elements, but are instead implemented by program sequences which are processed by the microprocessor mentioned.
  • the burner controller 1 has a further interface 29 to which a supply air temperature sensor 30 can be connected.
  • This interface 29 is connected on the one hand to the setpoint generator 27 and on the other hand to the programmer 20.
  • the "OFF" state is assumed as the initial state.
  • the higher-level heating controller not shown in the figure, does not require any heat, so that the burner is switched off.
  • the burner controller 1 is in the “standby” state, in which the fuel preheater 8 and the ignition device 10 are switched off, the fan drive 2 and the fuel pump drive 4 are at a standstill and the flame monitor 11 is not allowed to report a flame.
  • a signal appears at the entry point 13.m indicating the size of the heat demand.
  • This signal can be, for example, a standardized voltage in the range from 0 to 10 V, 10 V meaning 100% power requirement (based on the nominal power of the burner), but alternatively also advantageously a digital signal.
  • This signal reaches the programmer 20, in the case of a microprocessor as programmer 20 and an analog input signal via an analog-digital converter, not shown.
  • the programmer 20 starts the commissioning process with this signal.
  • the programmer 20 fetches a value for the speed of the blower drive 2 from the setpoint data memory 22 and the supply air temperature stored at this speed, which prevailed when the corresponding setpoint for the speed of the blower drive 2 was determined, which will be described in detail later.
  • the program generator 20 also has the value for the supply air temperature measured at the moment.
  • the programmer 20 now determines a corrected setpoint for the speed of the blower drive 2 from the existing setpoint for the speed of the blower drive 2, from the stored value of the supply air temperature and from the current value of the supply air temperature.
  • the predefined algorithm is essentially based on the equation of the General Gas Act.
  • the corrected setpoint is written into the setpoint data memory 22 as the current setpoint.
  • the blower drive 2 is controlled accordingly by the programmer 20 via the control connection 6s.
  • the blower 3 should then start up and, after a certain run-up time, reach the target speed according to the corrected value. An initially increasing signal for the speed appears at the feedback connection 6r, which reaches a certain value after the ramp-up time has elapsed.
  • This signal passes from the feedback connection 6r to the actual data memory 23 and is stored there.
  • the comparator 24 now compares the values of the target data memory 22 and the actual data memory 23 and reports the result to the programmer 20. It should be mentioned here that, depending on the type of programmer 20 used, certain variants of the structure of the burner controller 1 are possible. If the program generator 20 is a microprocessor, the comparator 24 can also be a program sequence that the microprocessor processes.
  • an additional Air pressure switch must be present. By running the blower 3, an increased air pressure is generated, to which this air pressure switch responds. The response of the air pressure switch is communicated to the programmer 20. If the air pressure switch does not respond, the continuation of the program sequence is stopped. This measure ensures that the burner cannot go into operation if the fan drive 2 is running correctly, but the required air mass flow is not promoted by any circumstances.
  • the ignition device 10 is then switched on by the programmer 20 in that the ignition relay 19 is activated.
  • the fact that the ignition device 10 actually receives voltage has the prerequisite that the current path via the safety temperature limiter 14 and the protective relay 17 is closed.
  • the programmer 20 also fetches from the setpoint data memory 22 a setpoint for the speed of the fuel pump drive 4 belonging to the original, not temperature-compensated setpoint for the speed of the fan drive 2.
  • the fuel pump drive 4 is controlled and monitored in the same way as the fan drive 2.
  • the programmer 20 then controls the fuel valve relay 18, thereby releasing the flow of fuel so that the fuel-air mixture in the burner can now ignite.
  • the programmer 20 reads the value for the heat requirement at the input point 13.m, and the setpoint values for the speeds of the blower drive 2 and fuel pump drive 4 corresponding to this power value from the setpoint data memory 22 fetched and the motors regulated accordingly.
  • the setpoint for the speed of the fan drive 2 is in turn corrected as previously indicated in accordance with the current supply air temperature.
  • the entry point 13.m is queried cyclically by the programmer 20. Any change in Heat demand leads to a corresponding change in the setpoints for the speeds of blower drive 2 and fuel pump drive 4.
  • the setpoint data memory contains quartets of values: burner output, speed of blower drive 2, speed of fuel pump drive 4, supply air temperature.
  • the setpoint memory has a corresponding number of quartets of values, e.g. 128.
  • the setpoint memory only needs to record 3 quartets of values (start, 1st stage, 2nd stage), with single-stage burners only 2 ( Start, operation).
  • Generators for the control signals for fan drive 2 and fuel pump drive 4 are not shown in the figure. These generators can, for example, generate pulse-width-modulated or frequency-variant control signals. In the case of a microprocessor-controlled burner controller 1, these generators are not separate components, but the microprocessor acting as programmer 20 directly generates the corresponding signals.
  • the burner controller 1 is characterized in that the relationship between the speed of the blower drive 2 and the speed of the fuel pump drive 4 is determined by stored values, which can be freely selected, with each pair of values being assigned a supply air temperature for which the pair of values applies exactly. Since the speed of the blower drive 2 is corrected according to the invention in accordance with the ratio of the supply air temperatures at the time the setpoint is formed and at the time of the call-up, the optimum excess air can be set for each operating point under all circumstances. It is advantageous that the variants of the burner controller 1 for single-stage, two-stage and modulating burners differ only in the size of the target data memory. As a result, large quantities and thus low manufacturing costs can be achieved.
  • the use of regulated DC motors as drives for blowers 3 and fuel pumps 5 has advantages in terms of robustness and size.
  • the use of DC motors with 35 V nominal voltage has additional advantages in terms of safety, e.g. Protection against accidental contact.
  • the program of the program generator 20 can advantageously be designed such that when the heat requirement is increased, the speed of the fan drive 2 is increased first and the speed of the fuel pump drive 4 is only increased after a delay. Conversely, if the heat requirement is reduced, the speed of the fuel pump drive 4 can first be reduced and the speed of the blower drive 2 can be reduced with a time delay. As a result, air surplus is briefly ensured during load changes, so that a lack of air with the resulting unfavorable emission values is reliably avoided.
  • the burner controller 1 By pressing the operating mode switch 28, it can be selected whether the burner controller 1 should control the combustion process according to the data stored in its target data memory 22 (position "RUN"), or whether new data should be obtained for the target data memory 22 ( "SET" position).
  • the programmer 20 can automatically switch the operating mode switch 28 to the "SET" position if there are no values in the target data memory 22. In this case, he can control an indicator lamp or output a message on the display that the "SET" mode is active by connecting an exhaust gas probe 26 to the burner controller 1 at the interface 25.
  • the operating mode switch 28 is automatically set to the "SET" position as soon as a signal from the exhaust gas probe 26 is present at the interface 25. This active relationship is indicated in the figure by a dash-dotted line between the interface 25 and the operating mode switch 28.
  • the programmer 20 executes a special “calibration” program.
  • An operating point is a certain desired burner output, which includes a certain amount of fuel and a certain amount of air.
  • the amount of air for each of the operating points is varied by acting on the blower drive 2 until the exhaust gas probe 26 detects a predetermined signal for the desired exhaust gas state, for example until the oxygen content in the exhaust gas is within a setpoint range.
  • the amount of air is varied in such a way that the starting values are always too large and then the amount of air is gradually reduced. This also ensures in the program sequence for determining the optimal target data that there is never a lack of air during combustion which would cause harmful exhaust gases.
  • the quantity of air belonging to a working point at which the exhaust gas composition corresponds to the desired values is stored in the target data memory 22 for the respective working point.
  • the current value of the supply air temperature is also stored for each of these working points. This creates the quartets of values mentioned: burner output, setpoint for blower drive 2, setpoint for fuel pump drive 4 and the associated supply air temperature.
  • the operating mode switch 28 is then - advantageously automatically - set to the "RUN" position.
  • the burner controller 1 then controls and regulates the burner and the organs for supplying fuel and air in accordance with the power requirement which is present at its inputs. It should be mentioned that it is also possible to specify the amount of air and adjust the amount of fuel as part of the processing of the various operating points and in the normal operation of the burner controller 1.
  • the programmer 20 does not have to go to too many operating points as part of the "oak" program. Therefore it is advantageous if at measured working points Intermediate values are interpolated. The result of this is that the processing of the "oak" program is completed more quickly and heat is not produced unnecessarily. The latter is particularly advantageous if the first start-up or a new calibration takes place in the context of a chimney sweep in summer. If the burner were in operation for a long time and the heat produced was not removed, the safety temperature limiter could respond and the complete "calibration" program could not be carried out.
  • the number of working points can advantageously be selected independently: first three working points, a minimum power N min , a medium power N medium and a maximum power N max are measured. If the three points for the setpoint of the control values for fuel and air are not nearly on a straight line, intermediate points are measured. If these are still not nearly on a straight line with the neighboring points, further intermediate points are measured. The setting procedure is thus automatically optimized with regard to the linearity of the actuators.
  • the invention offers a number of advantages over the known.
  • an expensive and maintenance-intensive exhaust gas probe 26 is not required for the normal operation of the furnace, which is of great importance in smaller heating systems.
  • the emission values of the heating system operated with the burner controller 1 are reduced compared to the known one.
  • the data memory of the burner controller 1 is automatically populated with values for the quartets burner output / fuel quantity / air quantity / supply air temperature, in which optimal combustion with minimal Emission values takes place. A setting by a designated specialist is not necessary.
  • This procedure automatically takes into account different types of devices that serve to regulate the fuel and air volume. It is not necessary to enter the characteristics of such devices, so that the person responsible for the setting does not even have to know the technical data of the actuators.
  • the solution described can be used in the same way for non-modulating and modulating burners. It is particularly advantageous for modulating burners because the conventional process for defining and entering the quartets of burner output / fuel quantity / air quantity / supply air temperature is extremely time-consuming and, due to the implementation by a specialist, is also cost-intensive.
