Definitions

  • the invention relates to a device for controlling the gas / air ratio for a premixing combustion device.
  • the volume flow of the gas is kept in a constant relationship to the volume flow of the air. This is done by means of a pressure-controlled regulator in the gas path.
  • a pressure difference is used as a control pressure for regulating the gas volume flow, in direct dependence on the intake volume flow of the air.
  • the control pressure for the regulator is generated in a mixing device or at a diaphragm in the airway.
  • the pneumatic composite systems do not require electrical or electronic components. Their mechanical structure is very simple and works very fast. They only need a few moving parts.
  • the mixture preparation with pneumatic composite has the advantage of reacting very quickly to pressure and volume flow fluctuations in the incinerator and to keep the gas / air ratio constant in a large modulation range. As a result, these robust systems have proven themselves on many systems.
  • the set minimum power must not be below a value of 15 to 20% to ensure long-term combustion quality.
  • a sensor measures the composition of the combustion gases in the flame or after the flame or also the flame temperature.
  • the sensor generates a signal that is evaluated by an electronic controller. This controls an actuator, which determines the amount of gas.
  • These electronic composite systems are slower in balancing the change in airflow.
  • the sensors used are sensitive and of limited life. For safe operation of the incinerator a perfect sensor signal is required. However, fluctuations in gas quality, air pressure and combustion air temperature can be compensated.
  • the invention has for its object to realize the advantages of the systems with electronic composite in a system with pneumatic composite without abandoning the advantages achieved there.
  • the controller represents the system's pneumatic system and the sensor provides the signal that enables the gas quality, air pressure and combustion air temperature to be adjusted.
  • the cone which is preferably actuatable by a linear motor, is adjusted and thereby moves more or less deeply into the nozzle connected to the air line.
  • the sensor can detect the composition and / or the temperature of the combustion exhaust gases, and the electronics can determine from this the upcoming values of the gas quality, the air pressure and the combustion air temperature, so that a corresponding control over the adjustment of the cone is made possible.
  • the speed increases as the air enters the mixing chamber. This creates a stronger negative pressure in the annular gap connected to the gas line, which increases the amount of gas entering the mixing chamber.
  • the inflowing air quantity is reduced by the cross-sectional constriction of the nozzle connected to the air line. As a result, more gas is delivered to the mixing chamber with less air.
  • the degree of modulation is increased according to the invention, so that inaccuracies can be compensated even at low powers.
  • the cone can completely close the nozzle connected to the air line.
  • the combustion device is connected to an exhaust system, the other, with excess pressure in the exhaust gas combustion devices is available, it is prevented in this way that exhaust gas flows back into the air line of the deactivated combustion device.
  • the cone is moved completely out of the nozzle connected to the air line.
  • the minimum power of the combustion device is raised so far that the combustion is maintained in an operating range that does not necessarily require the intervention of the sensor. For example, the minimum power is increased to about 20%.
  • the basic setting of the pneumatic regulator ensures that a sufficiently high excess air is maintained for the expected gas types, air temperatures and altitudes.
  • the control corresponds to a conventional pneumatic composite.
  • the incinerator does not have to be shut down and pollutant emissions remain below the prescribed levels Limits.
  • Previously known systems with electronic composite must be turned off when selecting the sensor.
  • Variations in gas quality, air pressure, and combustion air temperature can be controlled without sacrificing the benefits of the pneumatic assembly, namely, rapid response to power changes and pressure fluctuations.
  • the combustion device also works in the event of sensor failure, as the pneumatic assembly on which the control is built remains functional.
  • a control with pneumatic composite which has a venturi nozzle-like extended mixing chamber, can also be retrofitted with a sensor-controlled cone.
  • the degree of modulation is increased by allowing a smaller minimum power to be set. In the case of a pure pneumatic composite, sufficient stability of the gas / air ratio is not ensured with such small powers.
  • the start / stop emissions are minimized by requiring fewer circuits because of the smaller minimum power.
  • the combustion device can be completed with other incinerators to a common, working with pressure exhaust system without the risk that at standstill of the combustion device exhaust flows back into the installation space, since the cone can completely close the air line.
  • the opening angle of the nozzle connected to the air duct substantially corresponds to the angle of the cone. This contributes to the nozzle connected to the air line being completely closable by the cone, as is provided in a development of the invention.
  • cones with an angle of less than 30 ° It has been found to be particularly advantageous to provide the cone with an angle of less than 30 °. This angle allows a very sensitive adjustment of the cone and thus a very sensitive control. However, cones with an angle of more than 30 ° may also be possible.
  • the device according to FIG. 1 has a gas line 1 and an air line 2. Between the two lines operates a pneumatic regulator 3, which controls the pressure in the gas line 1 in response to the pressure in the air line 2.
  • the gas line 1 and the air line 2 open together in a mixing device 4. Downstream of the mixing device 4, a speed-controllable fan 5 is arranged, which promotes the mixture to a combustion device, not shown.
  • FIG. 2 shows in detail the construction of the mixing device 4, to which the fan 5 is connected directly.
  • the latter is driven by a variable speed motor 6.
  • the mixing direction 4 has a mixing chamber 7, which widens venturi-like in the flow direction from its inlet opening.
  • In the inlet opening of the mixing chamber 7 projects into a nozzle 8, which is connected to the air line 2.
  • the nozzle 8 forms with the edge 9 of the inlet opening of the mixing chamber 7 an annular gap 10 which is connected to the gas line 1.
  • a cone 11 is arranged, which is adjustable by a linear motor 12 in the axial direction relative to the nozzle 8.
  • the cone 11 is controlled by a sensor, not shown, which detects the composition of the combustion exhaust gases in the present case. It provides a signal representing the upcoming gas quality.
  • the cone 11 In the position of Figure 2, the cone 11, the angle in this embodiment is less than 30 ° and coincides with the opening angle of the nozzle 8, projects into the latter. If the gas quality changes in the direction of lower calorific value, the linear motor 12 displaces the cone 11 to the left into the nozzle 8. This increases the speed at which the air enters the mixing chamber 7. Accordingly, more gas is conveyed into the mixing chamber 7. At the same time, the amount of air entering the mixing chamber 7 decreases. As a result, less air promotes more gas in the mixing chamber 7. This compensates for the decreasing calorific value.
  • the invention combines the advantages of a pneumatic composite with the advantages of an electronic composite while simultaneously increasing the degree of modulation.
  • the minimum power of the combustion device can be lowered without loss of stability.
  • the cone 11 can be driven so far into the nozzle 8, that he closes the latter. This prevents an exhaust gas backflow into the air line 2, provided that the combustion device is connected to an exhaust system, which is acted upon by further combustion devices with overpressure.
  • the cone 11 is driven so far to the right that it completely clears the cross-section of the nozzle 8.
  • the combustion device is then controlled solely by the pneumatic regulator 3, ie in the conventional manner of a pneumatic composite. It is advisable to increase the minimum power of the connection device.
  • the pneumatic controller 3 can tap the control pressure for controlling the pressure in the gas line 1 elsewhere than in the air line 2, for example in the mixing chamber 7.
  • the linear motor 12 controlling sensor for example, only the combustion air temperature and / or Record air pressure or gas quality.
