Definitions
- the invention relates to a method for controlling a firing device, in particular a gas burner, and a firing device, in particular a gas burner, which comprises a gas valve for adjusting the fuel supply to the firing device.
- the power output is essentially determined by the setting of the supply of Fuel gas and air and determined by the set mixing ratio between gas and air.
- the temperature generated by the flame is also a function of the mixing ratio between gas and air.
- the mixing ratio can be specified, for example, as the ratio of the mass flows or the volume flows of the air and the gas. However, other parameters, such as the fuel composition, have an influence on the sizes mentioned.
- a mixing ratio can be determined which maximizes the effectiveness of the combustion, i. where the fuel burns as completely and clean as possible.
- known gas burners are usually equipped with a radial fan, which sucks the mixture of air and gas during operation.
- the adjustment of the mass flows of air and gas can be done for example by changing the speed and thus the suction of the impeller of the radial fan.
- valves can be provided in the gas and / or air supply line, which can be actuated to set the individual mass flows or their ratio.
- various sensors can be arranged at suitable locations.
- appropriate measuring devices can be provided for measuring the mass flow and / or the volume flow of the gas and / or the air and / or the mixture.
- state variables such as the temperature of the air, pressures, etc., can be measured at appropriate locations, evaluated and used for the control.
- the regulation of the mixing ratio is done today by default, especially for gas burners used in the household, by pneumatic control of a gas valve in dependence on the volume flow of the supplied air quantity (principle of pneumatic composite).
- pneumatic control pressures or pressure differences on orifices, in constrictions, or in venturi nozzles are used as control variables for a pneumatic gas control valve that adjusts the gas supply to the airflow.
- a disadvantage of the pneumatic control is in particular that mechanical components must be used which are subject to hysteresis effects due to the friction. Especially at low working pressures, inaccuracies in the control, so that the blower must always produce a certain minimum pressure to achieve a sufficiently precise control, which inversely leads.
- the use of the electronic interconnect also presents situations that can not be adequately addressed, such as a change in sensitivity of the sensors due to contamination.
- the DE 100 45 270 C2 discloses a firing device and method for controlling the firing device with fluctuating fuel quality.
- the fuel-air ratio becomes corresponding changed.
- the mixture composition is adjusted for each suitable type of fuel until the desired flame core temperature is reached.
- maps are used for different fuels, from which a new, suitable fuel-air ratio is read out whenever the performance requirements change.
- a derivative component for the control signal of the gas valve is derived from the speed change of the air blower. Since the power control signal characteristic is known and stored in an evaluation circuit, the derivative part can be determined.
- the reference signal J ' ie a change in the power requirement
- the speed of the fan is changed. This change in the speed determines via an adder a positive or negative derivative part, by which the control signal is adjusted. The resulting control signal changes accordingly the position of the gas valve.
- the EP 1 293 727 A1 further discloses a burner control apparatus using an ionization electrode and a calibration unit.
- a control system for a gas burner is shown.
- the regulation takes place here using a temperature measured at the burner surface. Since the surface temperature depends on the flow rate of the air-gas mixture, falling below a certain temperature, the speed of the fan motor is lowered, whereby the air flow and thus the air-gas ratio is lowered.
- a method for controlling a gas burner is known in which the CO concentration in the exhaust gases of the burner flame is detected with an exhaust gas sensor.
- a certain CO value corresponds to a certain gas-air ratio.
- gas-air ratio at a certain CO value a desired gas-air ratio can be set.
- the EP 770 824 B1 shows a control of the gas-air ratio in the fuel-air mixture by measuring a Ionisationsstrorns, which depends on the excess air in the exhaust gases of the burner flame. In stoichiometric combustion is known a maximum of the ionization current is measured. Depending on this value, the mixture composition can be optimized.
- a disadvantage of the last-mentioned method is that the feedback signal can only be detected when the flame is burning and fed back to the control loop.
- the inertia of the sensors limits accurate readjustment.
- the sensors used are subject to contamination, so that the combustion is suboptimal regulated over time and thus increase the pollutant levels.
- pneumatic regulator which, however, increases the complexity of the plant as well as the costs.
- the inventive method for controlling a firing device is characterized by the combination of features according to claim 1.
- the actuators such as the fan or a gas control valve
- a certain period of time which depends on the inertia of the sensors, be readjusted. It thus takes place in the execution of the method according to the invention, a transition from a pure control to a control.
- the parameter corresponding to the burner load is the mass flow of the air to be supplied to the firing device.
- the opening values of the gas valve can therefore be represented in this embodiment as a function of the mass of the air.
- the characteristic of this characteristic is determined inter alia by the properties of the gas valve.
- the burner load is substantially proportional to the amount of air supplied to the gas burner per unit time.
- the change of the opening of the gas valve may be performed by the modulation of a pulse width, by the variation of a voltage or a current of a valve spool, or by the operation of a stepping motor of a valve.
- Exceeding the upper or lower limit of the opening of the gas valve can be detected in the process. While after the control process, the opening of the gas valve is between the upper and lower limit, after the control step, the gas opening may be above or below the upper or lower limit. This can occur, in particular, if the setpoint values for the opening of the gas valve that are defined when the characteristic curve is generated deviate greatly from the optimally adjusted values. This can be due to changes in the fuel composition, changes in the measurement characteristics of the sensors or the settings of the system parameters.
- the characteristic resulting from the opening values of the gas valve as a function of the parameter corresponding to the burner load is recalibrated based on the control unit operating parameters set by the controller. Falls after the regulation, the value of the opening of the gas valve from the through the upper and lower limits limited range, so a recalibration of the characteristic can be performed. For example, during this recalibration, the setpoints may be shifted so that the new setpoint line passes through the adjusted value for the opening of the gas valve. In the same way, the upper and lower limits can be shifted, so that the new setpoint curve is surrounded by a tolerance corridor, as in the previously valid characteristic curve.
- Exceeding the upper or falling below the lower limit can, in particular after the expiry of a predetermined period of time, lead to switching off the firing device. This measure can be based on both safety concerns and economic considerations. Control to a range outside the desired margin indicated by the limits may, for example, indicate an undesirable change in the default settings of the gas burner, so that it may operate in an unsafe or ineffective operating range. The device would have to be checked and maintained below.
- a firing device in particular a gas burner, comprises: a gas valve for adjusting the fuel supply to the firing device; a memory for storing set values that depend on a parameter corresponding to the burner load and upper and lower limits; a device for controlling the opening of the gas valve, which, in the event of a change of the parameter corresponding to the burner load from a starting value to a target value, adapts the opening of the gas valve from a first to a second opening value according to a stored nominal value, the second opening value between a stored upper and a lower limit, and wherein during the transition of the opening of the gas valve from the first to the second opening value, no control of the fuel supply is performed; Means for controlling, after reaching the target value of the parameter corresponding to the burner load, operating parameters of the firing device and means for recalibration a characteristic resulting from the set values for the opening (w) of the gas valve in dependence on the parameter (m L ), based on the operating parameters set by a controller following the control, when the valve opening (w)
- the gas valve may be an actuator, in particular a stepper motor, a pulse width modulated or a coil controlled by an electrical variable.
- the firing device has at least one mass flow sensor for measuring the amount of air supplied to the firing device per unit time.
- the firing device may further comprise a mass flow sensor for measuring the amount of fuel medium supplied to the firing device per unit time and / or the amount of the supplied mixture of air and fuel medium.
- the firing device in the region of the burner flame may have a device for measuring a temperature generated by the firing device.
- the temperature sensor may be arranged, for example, in the region of the flame, but also on the burner in the vicinity of the flame.
- a thermocouple can be used as a temperature sensor.
- FIG. 1 shows a gas burner in which a mixture of air L and gas G is premixed and burned.

- a mass flow sensor 2 measures the mass flow of the air L sucked in by a blower 9.
- the mass flow sensor 2 is arranged so that as laminar a flow as possible is generated in its environment in order to avoid measurement errors.
- the mass flow sensor could be arranged in a bypass (not shown) and using a laminar element.
- a valve 3 may be arranged for the combustion air. However, however, usually a regulated fan with air mass flow sensor will be used, so that the valve can be omitted.
- a gas supply section 4 is provided, which is connected to a gas supply line.
- the gas flows through the section 4, during operation of the gas burner.
- a valve 6, which may be an electronically controlled valve the gas flows through a conduit 7 into the mixing region 8.
- a mixing of the gas G with the air L takes place.
- the fan of the fan 9 is driven at an adjustable speed to suck in both the air L and the gas G.
- the valve 6 is adjusted so that, taking into account the other operating parameters, such as the speed of the fan, a predetermined air-gas ratio enters the mixing area 8.
- the air-gas ratio should be chosen so that the most clean and effective combustion takes place.
- the air-gas mixture flows from the blower 9 to the burner part 11. There it exits and feeds the burner flame 13, which is to deliver a predetermined heat output.
- a temperature sensor 12 for example a thermocouple
- an actual temperature is measured, which is used in carrying out the method described below for controlling or controlling the gas burner.
- the temperature sensor 12 is arranged on a surface of the burner part 11. However, it is also conceivable to arrange the sensor elsewhere in the area of action of the flame 13.
- the reference temperature of the thermocouple is measured at a position outside the effective range of the flame 13, for example in the air supply line 1.
- a device, not shown, for controlling or regulating the air and / or gas flow receives input data from the temperature sensor 12 and the mass flow sensor 2 and outputs control signals to the valve 6 and to the drive of the blower 9.
- the opening of the valve 6 and the speed of the fan of the fan 9 are adjusted so that the desired air and gas supply results.
- control device has a memory for storing characteristic curves or nominal values as well as a corresponding data processing unit which is set up to carry out the corresponding methods.
- FIG. 2 is a dependence of the opening w of the gas valve 6, which determines the fuel supply, shown in dependence on the mass flow m L of the burner supplied air.
- the mean curve K3 corresponds to a desired value curve which indicates the predetermined opening values w soll of a gas valve 6 as a function of a corresponding air mass flow m L.
- the air mass flow m L is changed from an initial value m L1 to a second value m L2 and adapted to the new load Q 2 .
- the control is switched off and the opening value w of the gas valve from previously set value w 1 changed to a new target opening value w 2 ,
- the value w 2 is on the target opening curve K3.
- the adjusting opening of the gas valve is in any case between an upper limit curve K1 and a lower limit curve K2, which indicate a tolerance range for the opening of the gas valve.
- the upper limit curve K1 corresponds to a maximum allowable opening of the gas valve
- the lower limit curve K2 a minimum allowable opening of the gas valve. 6
- the operating parameters of the firing device in particular the setting of the valve 6 and the speed of the fan of the fan 9 are adjusted so that the combustion process is optimized.

- the control can for example take place as in the method described above.
- pulse width modulated valves electronically controlled valves or valves with a stepper motor actuated actuator.
- the control signal for adjusting the opening of the gas valve can accordingly trigger, for example, the operation of a stepping motor, or change the pulse width, the voltage or the current of a coil.
- the air mass flows m L and gas mass flows m G are measured by mass flow sensors 2 and 5.
- a valve opening w which lies above the upper limit curve K1 or below the lower limit curve K2 is now set in one phase of the method before or after the control process has been carried out, appropriate consequences can be drawn.
- leaving the tolerance corridor lying between K1 and K2 can lead to a calibration process.
- the setpoint curve K3 like the limit curves K1 and K2, can be shifted so that a uniform tolerance corridor for the opening of the gas valve 6 around the setpoint curve K3 also results in the new curve.
- exceeding the limit curves K1 or K2 upwards or downwards after a certain period of time or in case of repeated overshoot or undershoot can cause the device to be switched off. It may happen that certain gas burner settings change over time or certain boundary conditions have changed so that a safety hazard occurs or the gas burner operates in a non-effective operating state.
- a deviation of the opening of the gas valve from the permitted corridor can be triggered for example by a deviation of the gas pressure from the permissible inlet pressure range or by a malfunction of the sensors. The shutdown can thus be interpreted as an indication that a review and maintenance of the device is required.
