    BE2016 / 0179 "Heater device"
    Field of the invention
    The present invention relates to a heating device device comprising a control and / or regulation unit for controlling and / or regulating the air coefficient.
    The invention also relates to a method of implementing such a heater device.
    State of the art
    According to the state of the art, for example DE 196 18 573 Cl, DE 196 27 857 A1, EP 2 667 097 A1, heating device devices are known comprising a control and / or regulation unit for controlling and / or regulate the air coefficient.
    Presentation and advantages of the notice
    The subject of the present invention is a heating device device comprising a control and / or regulation unit for controlling and / or regulating an air coefficient, this heating device device being characterized in that the unit control and / or regulation takes into account at least one characteristic of the gas density for the control and / or regulation of the air coefficient.
    A heater device according to the present invention is in particular a part and more precisely a subset of a heater. The heater device can also designate the entire heater and preferably the entire instantaneous water heater. In particular, the heating device device comprises at least one heating unit, at least one modular and / or switched fan for supplying combustion air and / or at least one modular, and / or fuel regulating valve. or switchable to supply fuel. In this context, a heating unit designates in particular a unit making it possible to transform energy, in particular bioenergy and / or preferably fossil energy, in particular directly into heat and in particular to supply this heat to a fluid and advantageously to water. The unit
    BE2016 / 0179 heating comprises in particular a heating module for burning a mixture, in particular a mixture of combustion air and a fuel and advantageously at least one heat exchanger. The heating module is advantageously a burner, preferably a gas fan burner.
    The expression "intended for" indicates in particular that a means is specially programmed, designed and / or equipped to perform a certain function. The fact that an object is provided to perform a specific function means in particular that this object performs and / or performs this specific function in at least one state of application and / or operation.
    A “control and / or regulation unit” designates in particular an electrical and / or electronic unit with at least one control electronics. Control electronics according to the present invention designate a unit comprising a calculation unit and a memory unit as well as a command and / or regulation management program recorded in the memory unit and which can in particular be executed by the 'unit of calculation. In particular, the control and / or regulation unit provides a control signal for regulating and / or activating a blowing machine, in particular a blowing machine for combustion air and / or the fuel regulation valve. The control and / or regulation unit ensures the adjustment and / or activation of the blowing machine and / or of the fuel valve to regulate the heating power, in particular the heating power required and / or the power of set heating.
    The "air coefficient" designates in particular a coefficient depending on the combustion air / fuel ratio which fixes the quality of combustion and / or with which the quality of combustion can be known. In particular, the air coefficient corresponds to the ratio between the quantity of air actually contained in the mixture formed by the combustion air and the fuel and the stoichiometric quantity of combustion air necessary to ensure complete combustion. An air coefficient of value 1 thus corresponds to the stoichiometric ratio of combustion air. Advantageously, the air coefficient corresponds to a control and / or regulation quantity, direct and / or indi3
    BE2016 / 0179 recte. To achieve optimal combustion, in particular to have a stable heating flame, a minimum rejection of pollutants and / or a maximum efficiency, the set air coefficient is in the lean range of the mixture, in particular of the mixture formed by combustion air and fuel; this ratio is in particular between 1.15 and 1.45, preferably between 1.2 and 1.4 and in a particularly preferred manner, between 1.25 and 1.35.
    In the present context, the characteristic of the density of the gases represents in particular a characteristic which contains at least information relating to the density of the material in the gaseous state or of a mixture of materials in the gaseous state. In particular, the characteristic of the density of the gases contains at least one item of information representing the density of the combustible gas supplying the burner, that is to say of the combustion air supplied to the burner and / or of the mixture of gases and combustion air supplying the burner. The characteristic of the gas density is captured in particular by means of a sensor installed in the gas stream supplying the burner. The characteristic of the density of the gases can be entered in particular at fixed intervals and / or preferably continuously.
    Such an embodiment gives the heating device device as defined above, advantageous operating properties. In particular, taking into account a characteristic of the density of the gases for controlling and / or regulating the air coefficient, one compensates for the variations linked to the variation in the density of the combustible gases, of the oxidizing air and / or of the combustible gas-oxidant air mixture. In addition, this advantageously guarantees optimum combustion with a stable flame, a minimum emission of pollutants and / or a maximum efficiency, which in particular improves operating safety.
    According to a preferred development of the invention, the gas density characteristic is the temperature of the gases. The temperature of the gases according to the invention designates the temperature of the combustible gases supplying the burner, that of the combustion air supplying the burner and / or that of the gas-air combustion mixture supplying the burner. Preferably, the comBE2016 / 0179 heater device carries a temperature sensor unit for capturing the temperature of the gases and supplying this temperature to the control and / or regulation unit. In particular, the control and / or regulation unit makes it possible, using the temperature of the gases, to determine the density of the gases, in particular that of the combustible gases, that of the combustion air and / or of the gas mixture. fuel-combustion air and / or gas temperature to obtain the density of the gases, in particular that of the combustible gases, that of the combustion air and / or that of the fuel gas-combustion air mixture and / or to calculate this temperature. This results in an advantageously simple entry in metrology, of the gas density characteristic.
    In particular, the temperature sensor unit captures the temperature of the combustible gases, that of the combustion air and / or that of the fuel gas-combustion air mixture and supplies this temperature to the control and / or regulation unit.
    Preferably, the temperature sensor unit captures the temperature of the combustion air and supplies it to the control and / or regulation unit. As the density of the combustion air varies more than that of the combustible gas as a function of temperature, and since the measurement of the temperature of the combustion air is advantageously simple in metrology, we obtain by entering the temperature of the combustion air, advantageously, a determining characteristic of the density of the gases.
    According to another characteristic, the heater device comprises at least one ionization probe for capturing the ionization current in the combustion flame. In particular, the ionization current is correlated with the air coefficient. In particular, the ionization probe supplies the ionization current to the control and / or regulation unit.
    In particular, the control and / or regulation unit determines the air coefficient from the ionization current. This makes it possible to advantageously determine, in a simple and / or reliable manner, the air coefficient.
    According to another development of the invention, the control and / or regulating unit determines the actual power of the heaterBE2016 / 0179 fage from the speed of rotation of a blowing machine and the characteristic of the density of the gases. In particular, the control and / or regulation unit determines the actual heating power from the speed of rotation of the blowing machine and from the gas density characteristic. In particular, the control and / or regulation unit determines from the heating power deducted from the speed of rotation of the blowing machine, taking into account the gas density characteristic. In addition, the control and / or regulation unit controls the air coefficient from the actual heating power and / or regulates this air coefficient. This advantageously makes it possible to compensate for the differences between the supposed heating power and the real heating power.
    According to another characteristic, the control and / or regulation unit modifies the ionization characteristic as a function of the characteristic of the density of the gases. The ionization characteristic or ionization characteristic curve designates a curve which represents the ionization current with respect to the heating power. Advantageously, the ionization current is represented as a function of the heating power. The ionization current varies in particular with the heating power. The ionization current also varies in particular with the characteristic of the density of the gases. The characteristic curve designates in the present context a reference curve and / or a reference table with characteristic values, in particular reference values. In particular, the characteristic curve represents a characteristic value as a function of another characteristic value.
    Advantageously, the characteristic is presented under a table of values recorded in the memory unit. The command and / or regulation unit shifts the ionization characteristic (ionization characteristic curve) as a function of the characteristic of the density of the gases, recalculates and / or completely redefines this value. Alternatively, several ionization curves or characteristics can be recorded for different gas density characteristics in the memory unit and the control and / or regulation unit selects the ionization characteristic curve (or characteristic
    BE2016 / 0179 ionization) depending on the gas density characteristic. This advantageously makes it possible to correct the characteristic ionization curve as a function of the density characteristic of the gases.
    According to another development of the invention, the control and / or regulation unit modifies the speed of rotation of a blowing machine as a function of the gas density characteristic. In particular, the control and / or regulation unit modifies the speed of rotation of the blowing machine to adapt the actual heating power to the power demanded. This advantageously compensates for differences between the admitted heating power and the actual heating power.
    According to another development of the invention, the control and / or regulation unit modifies the position of the fuel gas valve as a function of the gas density characteristic. In particular, the control and / or regulation unit modifies the position of the fuel gas valve to adapt the actual heating power to the requested power. This compensates for the difference between the allowed heating power and the actual heating power.
    The invention also relates to a heating appliance, in particular a gas burner with a blowing machine comprising a heating appliance device according to the invention. This allows the heater to provide advantageously optimized combustion with a stable flame, emission of pollutants reduced to a minimum and / or maximum efficiency.
    The subject of the invention is also a method for managing a heating device device, the control and / or regulation of the air coefficient taking account of a characteristic of the density of the gases. This allows the control and / or regulation of the air coefficient to compensate for variations modifying the density of the combustible gas, the combustion air and / or the fuel gas-combustion air mixture. This advantageously makes it possible to have optimal combustion with a stable flame, an emission of polluting materials reduced to the minimum and / or a maximum output, which in particular increases the operational safety.

    Drawings
    The present invention will be described below in more detail with the aid of an example of a heating device device and its management method represented in the appended drawings in which:
    - Figure 1 is a diagram of a heater, Figure 2 is a diagram showing the relationship between the speed of rotation of a blowing machine and the heating power of the heater, and Figure 3 shows a diagram of the ionization current curves as a function of the density of the combustion air.
    Description of an embodiment
    FIG. 1 schematically shows a heater 26. The heater 26 is for example in the form of a gas burner with a blowing machine. The heating device 26 includes a blower machine 22 with variable speed for supplying combustion air 16. The blower machine 22 delivers a flow of combustion air and / or regulates this current. The heater 26 has an electronic fuel gas valve 24, with variable flow, for the fuel gas 28. The fuel gas valve 24 provides the transfer and / or regulation of the fuel gas stream. The heating device 26 also includes a heating unit 30. The heating unit 30 burns the combustible gas-oxidant air mixture 32 by generating a combustion flame 20.
    The heater 26 has a device (heater) 10 having a control and / or regulation unit 12 for controlling and / or regulating the air coefficient. The control and / or regulation unit 12 takes account of at least one characteristic of the gas density for the control and / or regulation of the air coefficient. The gas density characteristic is at least the temperature of the gases. The heating device 10 comprises a temperature sensor unit 14 for entering at least the temperature of the gases and supplying it to the control and / or regulation unit 12. The temperature sensor unit 14 captures the temp8
    BE2016 / 0179 strikes the combustion air 16 and supplies it to the control and / or regulation unit 12. As a variant or in addition, the temperature sensor unit 14 captures the temperature of the combustible gas 28 and / or of the fuel-oxidant air mixture 32 and supplies this or these temperatures to the control and / or regulation unit 12. The control and / or regulation unit 12 determines from the temperature entered, the density of the gases, preferably the density of the combustion air 16 or alternatively and in addition the density of the combustible gas 28 and / or of the fuel gas-combustion air mixture 32. The heater 10 has an ionization probe 18 for enter the ionization current 48 in the combustion flame 20 and supply this ionization current to the control and / or regulation unit 12. The control and / or regulation unit 12 determines the coefficient of air from the ionization current.
    FIG. 2 shows a diagram representing the relationship between the speed of rotation 34 of the blowing machine 22 and the heating power 36 of the heater 26. The speed of rotation 34 is represented with respect to the abscissa axis 40 in revolutions per minute. The ordinate axis 38 represents the heating power 36 in kW. The diagram presents three curves 42, 44, 46 which show the influence of the density or the temperature of the combustion air 16 on the heating power 36 and the air coefficient. The first curve 42 shows the relationship between the speed of rotation 34 of the blowing machine and the heating power 36 for a nominal temperature of the combustion air 16; we have an air coefficient equal to 1.3. The second curve 44 presents the relationship between the speed of rotation 34 of the blowing machine and the heating power 36 for the reduced nominal temperature of the combustion air 16. The reduced temperature results in a higher density of the combustion air 16 and thus a higher oxygen content per unit volume. For the same speed of rotation 34 of the blowing machine, this results in a higher heating power 36 and in the reduction of the air coefficient, for example to 1.1. The third curve 46 shows the relationship between the speed of rotation 34 of the blowing machine and the heating power 36 for a temperature of the combustion air 16 noted by
    BE2016 / 0179 compared to the nominal temperature. This higher temperature results in a lower density of the oxidizing air 16 and thus a lower oxygen content per unit volume. For the same speed of rotation 34 of the fan, this results in a lower heating power 36 and in an increase in the air coefficient, for example to 1.5. There is thus a difference between the foreseeable heating power according to the speed of rotation 34 of the blowing machine and the real heating power 36. The control and / or regulation unit 12 determines the real heating power 36 from the speed of rotation 34 of the blowing machine and the characteristic of the density of the gases for controlling and / or regulating the air coefficient as a function of the real heating power 36.
    FIG. 3 shows examples of the characteristic ionization curve 52, 54, 56 as a function of the heating power 36. The first ionization curve 52 corresponds to the ionization current 48 for the nominal temperature of the combustion air. The second ionization curve 54 represents the ionization current 48 for a reduced combustion air temperature. The third ionization curve 56 shows the ionization current 48 for a recorded combustion air temperature. The ionization current 48 varies with the heating power 36. For a constant air coefficient (for example Xc - 1.3), in the zone 50 of low heating powers 36, the intensity of the current decreases so significant. In zone 50 of low heating powers 36, the ionization current is no longer unequivocally linked to the air coefficient. In particular in the zone 50 of low heating powers 36, the differences between the foreseeable heating power according to the speed of rotation 34 of the blowing machine and the real heating power 36, result in control and / or regulation of the air coefficient.
    The control and / or regulation unit 12 modifies the characteristic ionization curve 52, 54, 56 as a function of the characteristic of the density of the gases. In particular, the control and / or regulation unit 12 selects the characteristic ionization curve 52, 54, 56 in correlation with the density characteristic of the gases according to the current temperature of the combustion air 16. In particular, l 'unit of
    BE2016 / 0179 control and / or regulation 12 modifies the speed of rotation 34 of the blowing machine and / or the position of the fuel gas valve according to the characteristic of the gas density.
