Definitions

  • the invention relates to a method for regulating the flame quality of an atmospheric gas burner.
  • the fuel gas has been at least partially premixed with primary air and the fuel gas / air mixture thus produced has been Feed flame openings provided burner surface on which this fuel gas-air mixture burns in flames.
  • the remaining part of the necessary combustion air is supplied to the flame as secondary air within the combustion chamber.
  • the premixing is generally carried out in such a way that the fuel gas is introduced into a mixing chamber at a predetermined gas pressure via a gas nozzle, depending on the pulse of the fuel gas stream emerging from the gas nozzle and the geometric design of the mixing chamber, which is usually designed as a mixing tube, a certain volume flow of air is sucked in.
  • the mixture formation can be achieved at pressures corresponding to atmospheric pressure with the aid of a fan or a blower.
  • the gas volume flow is precisely matched to the wobbe number of the fuel gas used.
  • the primary air volume flow drawn in may be too high, depending on the change in the Wobbe number, so that the flame can be lifted and extinguished with high CO emissions. If the primary air volume flow is too low due to the wobbe number of the fuel gas, the flame moves very close to the burner surface, so that there can be a strong heating up to overheating and destruction of the burner surface.
  • the object of the invention is to create a method for regulating the quality of the flame in an atmospheric gas burner, which leads to an automatic adaptation of the primary air flow to the nature of the fuel gas.
  • a method for regulating the flame quality of an atmospheric gas burner in which the fuel gas is supplied via a Gas nozzle is introduced into a mixing chamber, into which a minimum volume flow of primary air is introduced via a supply cross-section in addition to the fuel gas, and the fuel gas / primary air mixture is introduced into the combustion chamber via a burner surface provided with flame openings, and the volume flow of the primary air depending on the Area of the burner surface prevailing combustion chamber temperature is changed between a predetermined minimum volume flow and a maximum volume flow.
  • This method has the advantage that the change in the primary air volume flow can be carried out directly as a function of the combustion chamber temperature, since a fuel gas with a low Wobbe number leads to a lower combustion chamber temperature and a fuel gas with a high Wobbe number leads to a correspondingly increased combustion chamber temperature. Since there is thus a direct connection between the Wobbe number and the temperature, the method according to the invention offers the possibility of regulating the amount of primary air required in accordance with the Wobbe number of the fuel gas, so that even with a change in the quality of the fuel gas during operation, the primary air volume flow is automatically adapted to this change he follows. This makes it possible to operate such an atmospheric gas burner even under changing conditions with high efficiency and the lowest possible exhaust gas emission without manual intervention on the burner setting.
  • primary air always relates to the admixture of a secondary medium to a fuel gas, so that the secondary medium can be both air and an exhaust gas / air mixture or a fuel gas / air mixture.
  • the combustion chamber temperature can be detected both by detecting the flame temperature, in particular the radiation temperature, of at least one flame, and also by detecting the temperature of a burner and / or combustion chamber component respectively.
  • the detection of the combustion chamber temperature via the radiation temperature of at least one flame leads to a change much faster than the detection of the combustion chamber temperature via the temperature of a burner and / or combustion chamber component is possible, since depending on the size of the mass and the material of the component greater specific heat capacity and thus a somewhat greater temperature persistence is available.
  • the change in a gas burner which is provided with an adjusting element for changing the intake cross-section the adjusting movement of the adjusting element is brought about by a temperature-dependent change in shape of an adjusting means which is exposed to the combustion chamber temperature.
  • combustion chamber temperature is to be understood in the sense of the above explanations about temperature detection.
  • This configuration has the advantage that the adjusting movement for adapting the primary air volume flow can take place without auxiliary energy, since the change in shape of the adjusting means can be converted directly into the adjusting movement.
  • the change in shape can consist of a simple change in length, a change in volume and a change in the component contour, as is the case, for example, with a bimetallic element.
  • the invention also relates to an atmospheric gas burner, in particular for using the method according to the invention.
  • the atmospheric gas burner is provided with at least one gas nozzle which opens into a mixing chamber to which a burner surface provided with flame openings is assigned, the mixing chamber having a primary air supply opening assigned to the gas nozzle, which has an adjustment element for changing the free flow cross section of the primary air Supply opening is provided, which is connected to an adjusting means, the temperature sensing communicates with the combustion chamber.
  • This arrangement has the advantage that the free flow cross-section of the primary air supply opening can be adjusted directly as a function of the combustion chamber temperature, in such a way that the primary air volume flow automatically adapts to any change in the gas quality.
  • the combustion chamber temperature also drops accordingly, so that the primary air volume flow is reduced accordingly via the adjusting element.
  • an adjustment possibility can be provided between the adjusting means and the adjusting element, for example to provide a "dead travel", so that the adjusting element only moves from a predeterminable or adjustable temperature.
  • the actuating means can be implemented in different ways.
  • the actuating means is formed by a bimetallic element which is connected to the adjusting element at one end outside the combustion chamber and which extends into the flame area of the burner at the other end. Characterized in that the end reaching into the combustion chamber is directly exposed to the temperature effects of the flame, there is an immediate implementation of each temperature change in an adjusting movement and thus in a change in the position of the adjusting element.
  • the end of the bimetallic element reaching into the flame region can be arranged at a distance from a flame on the burner surface, so that it is either exposed to the heat radiation of the flame or is located directly in the exhaust gas stream above the flame.
  • the arrangement is expediently such that this "temperature-sensing" end of the bimetal element is as little as possible or not at all is cooled by the entry of cold secondary air or by heat dissipation to surrounding combustion chamber parts.
  • the change in shape of the bimetallic element which is a function of the temperature, directly effects the actuating movement.
  • the actuating means is formed by a bimetallic element which is connected to the adjusting element at an end lying outside the combustion chamber and which is connected to the component of the combustion chamber which is exposed to heating by the burner at the other end is attached.
  • the bimetallic element due to the arrangement, there is a certain delay between the change in temperature in the flame area and the initiation of the actuating movement.
  • the advantage is that the "temperature-sensing" end of the bimetallic element is not directly exposed to the action of the flames and therefore longer service lives can be achieved.
  • the adjusting means is formed by an expansion tank filled with a medium that expands under the influence of temperature, which can be acted upon by the combustion chamber temperature and whose movable end is connected to the adjusting element.
  • an expansion container can be filled with a liquid or a gas, the container itself being designed to be expandable, for example in the form of a bellows, or else in the form of a piston-cylinder unit, the moving part of such a piston then -Cylinder unit acts on the adjustment element.
  • Liquids with a high boiling point must be used as the liquid and / or the part of the expansion tank exposed to the combustion chamber temperature must be arranged so that the boiling point is not reached even at the maximum achievable temperature. In any case, non-flammable liquids or gases must be used.
  • the actuating means is formed by an electric servomotor which is controlled via a control device with a temperature sensor assigned to the combustion chamber.
  • an auxiliary energy is required for the operation of the servomotor and for the usually electrical control device.
  • the advantage is that, on the one hand, by means of a corresponding design and / or programming of the control device and a corresponding temperature sensor, for example a radiation pyrometer or a thermocouple, a very sensitive control of the servomotor can be effected, which adjusts the primary air volume flow to an almost exact adjustment the temperature specified by the gas type supplied enables.
  • the adjustment element can be designed in a variety of ways.
  • the actuating element is formed by a slide, by means of which the primary air supply opening of the mixing chamber can be closed at least over part of its free cross section.
  • the slide can be part of the adjusting means, for example a bimetallic element, which covers one end of the free cross section.
  • the contour of the slide covering the primary air supply opening can be dimensioned such that, for example, non-linear actuating movements of the actuating means are correspondingly compensated for, so that there is a linear change as a function of the detected combustion chamber temperature with regard to the adjustment of the primary air volume flow.
  • any other characteristic of the change in the primary air volume flow can also be achieved via the appropriate shape of the contour cause.
  • Fig. 1 for an atmospheric gas burner consists essentially of a holding plate 1, which is provided with a primary air supply opening 2, the mouth for a tubular, for example trained mixing chamber 3 forms.
  • the end 4 of the mixing chamber 3 facing away from the primary air supply opening 2 opens into a distribution chamber 5, which is designed on its upper side as a burner surface 6, which is provided with a plurality of flame openings 7, so that this from the mixing chamber 3 into the distribution chamber 5 entering air-gas mixture can only enter the combustion chamber via the flame openings 7.
  • the primary air supply opening 2 is assigned a gas nozzle 8 with a corresponding distance, through which a fuel gas with the appropriate pressure and thus with the corresponding flow velocity flows through the primary air supply opening 2 into the mixing chamber 3 and thereby entrains air from the environment in accordance with the flow energy of the fuel gas.
  • the primary air supply opening 2 can be assigned a suction housing which is provided with inlet openings with a corresponding cross section.
  • the fuel gas is mixed with the primary air drawn in and then enters through the free opening at the end 4 into the distribution chamber 5, from which it then exits through the flame openings 7 into the combustion chamber (not shown here).
  • the fuel gas is ignited via an ignition device (not shown in detail), so that a corresponding number of individual flames is also present in accordance with the number of flame openings.
  • an additional opening (not shown here) in the combustion chamber, the individual flames then take up the secondary air required for complete combustion in addition to the admixed primary air.
  • the primary air supply opening 2 is assigned a slide-shaped adjusting element 9 on the support plate 1, which is guided on the support plate 1 so that it can be moved vertically up and down.
  • the adjusting element 9 is designed such that it at least partially covers the free cross section of the primary air supply opening 2 and thus reduces the free passage cross section accordingly. With a shift of the adjusting element 9 upwards, the free passage cross section of the primary air supply opening 2 is then released in accordance with the displacement path.
  • an adjusting means 10 is connected to the adjusting element 9.
  • the actuating means 10 is formed by a bimetal element which is connected to the adjusting element 9 by its end 11 lying outside the combustion chamber and which is connected to the other end 12 lying inside the combustion chamber into the flame area of the burner surface 6 enough.
  • the bimetallic element 10 is in this case firmly connected to the support plate 1, so that when the end 12 lying in the combustion chamber is subjected to a temperature, the bimetallic element 10 changes its shape and, with the end 11 lying outside the combustion chamber, the adjusting element 9 with corresponding assignment depending on the temperature exposure shifts upwards.
  • Fig. 2 shows an approximately larger scale a view of the adjusting element 9, which is shown in its fully raised position, so that the free passage cross section of the primary air supply opening 2 is completely exposed.
  • the minimum position is indicated by dash-dotted lines, it being evident that the covering of the free cross section of the primary air supply opening 2 is effected via a corresponding cutout 13 in the adjusting element 9.
  • FIG. 3 shows the arrangement described with reference to FIGS. 1 and 2 in a longitudinal section, in which the course of the flow is indicated by corresponding arrows.
  • the adjusting element 9 has a cutout 13 which allows adaptation to different operating states. Instead of a simple semicircle section, 1 and 2, in this exemplary embodiment the cutout 13 is provided in its region facing the free passage cross section of the primary air supply opening 2 with preferably symmetrically arranged cover contours 14.
  • the cover contours 14 are arranged and shaped in such a way that they bring about a reduction in the inflowing primary air for the "burner start" position shown in FIG. 4.1 when the combustion chamber is cold, irrespective of the wobbe number of the gas.
  • the adjusting element 9 is raised only to a small extent, so that the cover contours 14 are free according to the required reduction in the primary air volume flow Cover the cross section of the primary air supply opening 2 as far as possible, as shown in FIG. 4.2.
  • the adjusting element 9 is raised to such an extent via the correspondingly higher flame temperature that the free cross section of the primary air supply opening 2 is completely released.
  • This makes it possible, with a given gas nozzle 8 and a given free flow cross-section of the primary air supply opening 2, within the limits specified by the cover contour 14 for a correspondingly defined range of fuel gases with a different Wobbe number without manual control intervention to mix a predetermined mixing ratio with primary air.
  • the adaptation to the different Wobbe number takes place automatically as a function of the resulting flame or combustion chamber temperature, so that such an adaptation also takes place during operation when the fuel gas quality changes.
  • FIG. 5 shows in a longitudinal section corresponding to FIG. 3 a modified form for the adjusting means and the adjusting element.
  • the mouth area of the gas nozzle 8 is enclosed by an inlet housing 15 which surrounds the primary air supply opening 2 and which has a small primary air supply opening 16 which cannot be changed in cross section, by means of which the inflow of a minimum volume flow is ensured.
  • the inlet housing 15 is provided with a second primary air supply opening 18 in the form of an intake socket 17.
  • the primary air supply opening 18 of the inlet housing 15 can be closed by a flap-like adjusting element 9.1, which is formed by the end of a bimetallic element 10 lying outside the combustion chamber and which is connected to the other end 12, which extends into the flame region of the fuel gas .
  • the bimetallic element 10 In the cold state, the bimetallic element 10 is stretched, as indicated by the chain line, so that the primary air supply opening 18 is covered. Corresponding to the heating of the bimetallic element 10 as a function of the combustion chamber or flame temperature that is set, the adjusting element 9.1 is raised and the free cross section of the primary air supply opening 18 is more or less released depending on the temperature effect.
  • a metal spiral is arranged in the interior of the combustion chamber as the adjusting means 10.
  • the arrangement is such that the metal spiral, which consists of a metal with a good coefficient of thermal expansion, does not necessarily consist of a bimetallic strip must exist, with one end 21 is fixed to a fixed part of the combustion chamber.
  • the inner end of the spiral is connected to a rotatably mounted shaft 22, which is connected at its free end to an adjusting element 9.2 in the form of a throttle valve, via which the primary air supply opening 18 of the intake connector 17 can be closed.
  • a fixed stop for the throttle valve ensures that a minimum volume flow can always be drawn in, ie that the throttle valve cannot completely close the primary air supply opening 18, regardless of the temperature in the combustion chamber.
  • the arrangement is such that, as the temperature increases, the adjusting element 10 designed as a spiral rotates the throttle valve 9.2 into the open position.
  • the particular advantage of this embodiment is that the "zero position", as it must be specified for a fuel gas with a low calorific value, can be adjusted to the local conditions by a corresponding adjustment of the throttle valve or by a corresponding pre-tensioning of the spiral.
  • the adjusting means which is shaped as a spiral, must now be dimensioned such that the desired adjustment takes place between a low air requirement with a low heating value and a maximum air requirement with a high heating value.
  • the minimum air volume can be specified unchangeably by means of a corresponding cutout or a corresponding bore in the throttle valve itself.
  • the throttle flap is then pivoted over the horizontal position, so that a flap position “burner start” is given in addition to the volume flow predetermined by the minimum air volume.
