These measuring devices are used for setting heating systems. These devices have input keys, display, possibly printer and In addition to the measurement inputs mentioned above, interfaces with which the data obtained can be transferred to a printer or a computer.
  • the burner settings are optimized Measurement of values from the control device of the burner, a so-called Automatic burner controls can be obtained. To be able to take these measurements, the burner control can be partially opened or rewired. Among other things, are measured the mains voltage with a voltmeter, the sensor current of the flame sensor with a micro-ampere meter or voltmeter and the program times or flame formation time with a stopwatch. From the values of mains voltage and sensor current determined one after the other, a statement can be made about the sensor current at normal mains voltage, this statement by the in time Distance was measured and other fluctuations occurred during this period Interferences such as. the mains voltage is very imprecise.
  • Automatic burner controls for small and medium-sized burners generally have no displays Show information about malfunctions of the burner control, but only simple Status displays, mostly light emitting diodes or glow lamps. More elaborate displays are made Cost reasons omitted. Newer burner controls are known to have data on one Additional device with display to be transmitted, the communication via any serial Interface, e.g. via an infrared interface. Can on the display Information about the burner control or about faults in the burner control as Numeric code or in plain text.
  • a fitter or chimney sweep therefore needs service, maintenance and commissioning from Incinerators of the type described above several devices to do the appropriate work the measurements take a lot of time and are sometimes very imprecise. This increases the Effort and thus the cost of such a process.
  • an exhaust gas analysis device which has a Infrared interface Receive data from a burner control and evaluate it in the analyzer and can visualize on the display device.
  • the analyzer has two modes, one Exhaust gas analysis mode and a data evaluation mode. The analyzer thus only serves as Display for the data output from the burner control.
  • the present invention has for its object an analyzer, its use and Providing methods for measuring flue gases using an analysis device, which is simple and allow inexpensive maintenance, service and commissioning of incineration plants.
  • the essence of the invention is thus that means for joint processing of the data in the analysis device the data transmitted to the control and regulating device and the data determined from the exhaust system are arranged.
  • the control and regulating device 1 shows a control and regulating device 1, a so-called burner control, for one Burner 2.
  • the fuel is supplied to the combustion chamber 4 via a fuel line 3, the Amount of fuel is controlled by the control and regulating device 1 by means of an actuator 5.
  • the burner 2 is a gas burner, then the actuator 5 is a flap, the position of which is the gas flow controls. If the burner 2 is an oil burner, the actuator 5 is an oil pressure regulator.
  • One by one Motor 6 driven fan 7 feeds air into the combustion chamber 4. In the combustion chamber 4 the fuel-air mixture burned and the flue gases discharged via an exhaust system 8.
  • an analysis device for combustion systems 9 a so-called flue gas analysis device
  • the flue gases are measured in the exhaust system with regard to their composition, as well as the temperature and pressure via lines 10, 11 and specific sensors, not shown, and evaluated in the analysis device 9.
  • the sensors for measuring flue gases such as O 2 , CO 2 and CO can be arranged in the analyzer 9 or outside the analyzer.
  • the flue gases are usually sucked out of the exhaust system via a hose and fed to the sensor. This information thus obtained from the exhaust system can be shown on a display of the analysis device or output to a printer or computer 12 and processed further via an output unit.
  • the analysis device 9 is connected to the burner control unit 1 via a communication line 13.
  • the data can be transferred from the automatic firing device to the analysis device via any interface, for example via an optical interface arranged on the automatic firing device 1.
  • the sequential optical information output via the optical interface can be converted into the signal level of a serial interface of the analysis device by means of a scanning device (not shown).
  • the signals from the burner control are then processed further in the flue gas analyzer.
  • special programs are provided in the analysis device, which convert the signals from the burner control into corresponding displays on the display of the analysis device and can process the data supplied by the burner control. Fault messages, input and output states of the burner control, identifier, commissioning counter, service counter, mains voltage, flame intensity, or flame current, flame formation time, program phase, etc.
  • the incineration plant reduces the measurement effort and thus reduces the costs. Furthermore, the processing of all specific data of the incineration plant in one device 9 allows precise statements about the overall condition of the plant and, in the event of faults, about the exact cause of the fault. Due to the precise determination of the cause of the fault, only the components that are really defective and no longer have to be replaced as usual, several assemblies, such as the burner control and the fuel valve.
  • the measurement of the flue gases in the exhaust system can be done by processing the data in the Analyzer can be automated.
  • the information about the Combustion won and if there is stable combustion i.e. if e.g. the Flame flow is within certain limits, or a certain minimum time since the emergence Flame has passed or a certain boiler temperature has been reached, the flue gases measured. If the state of the combustion changes during the measurement and becomes unstable, the measurement of the flue gases can be interrupted immediately by the analyzer. This allows a reliable measurement of the flue gases without the sensors being burned by insufficient Flue gases are damaged, which increases the life of the sensors. At the same time Long-term measurement of the flue gases is possible using this method, e.g. over several days without that a technician or chimney sweep must monitor the measurement on site. This allows long-term statements about the condition of the incineration plants and thus also an improved analysis the condition of the system.
  • the controller 14 may be a boiler controller that controls the temperature, pressure of a heating system (not shown) that is heated by the combustion in the combustion chamber. If the pressure or the temperature in the heating system rises above a certain predetermined value, the controller 14 passes this information on to the automatic firing device via line 15, whereby the automatic firing device interrupts the combustion.
  • the information passed on from the controller 14 to the automatic firing device 1 can also be transmitted via line 13 to the analysis device and processed there. If the communication takes place bidirectionally via line 15, the information from the burner control can also be passed on to controller 14 via line 15 and to the analysis device via line 16.
  • the line 13 can be omitted and the communication between the automatic burner control and the analysis device takes place with the intermediary of the controller 14.
  • the controller 14 can, for example, also be an electrical compound controller which controls the actuator 5 and the motor 6, which is shown in broken lines in FIG.
  • the communication between the automatic burner control unit and the analysis device can of course also take place with the inclusion of controllers / devices not mentioned further, in which case the information contained in the devices can also be passed on to the analysis device.
  • the lines 13, 15, 16 can be configured as desired, so the communication can be unidirectional or bidirectional by means of a point-to-point interface as well as via a bus interface.
  • controllers and analyzer By combining controllers and analyzer, data exchange between the controllers and analysis device and the joint processing of data in the analysis device can be a Numerous advantageous configurations and improvements compared to conventional devices achieve.
  • the combustion process can be performed by measuring exhaust gas values and automatically Setting of the electrical network can be optimized.
  • the flue gas analyzer measures that Oxygen concentration in the flue gas and gives corresponding control commands to the automatic firing devices or the electrical connection.
  • the automatic burner control unit must adjust the air size at each working point until an optimal one There is combustion at every working point.
  • the connection between the flue gas analyzer and Automatic burner control can be done by bidirectional communication.
  • the combustion process can also be optimized with regard to the mechanical bond.
  • the setting of the primary air can be set manually via the Analyzer or done automatically via motor adapter. This process is not straightforward in connection with the burner control, but can be measured by the flame intensity and the time of the flame formation are sensibly supplemented.
  • the joint processing of data in the analyzer can be used to determine the Fuel consumption can be used via the burner control. This for example by means of a electric fuel flow meter or by determining the fuel pressure, the nozzle size and calculation over the burner runtime and evaluation / logging over the Exhaust gas analyzer. Through the annual exhaust gas analysis, an energy balance over the Heating system are made taking into account consumption and efficiency.
  • the optimal pre-ventilation time can be determined via the flue gas analyzer at the system service, taking into account the relevant parameters such as the O 2 content of the flue gas, stability of the combustion chamber pressure etc. This can save until the next check, taking into account the existing safety regulations.
  • the joint processing of data in the analyzer can be used to determine the optimal Interval time between the first and second burner stage or between the first burner stage to can be used to enable the controller.
  • the furnace pressure can be used to determine the time until the flame intensity and the furnace pressure has reached constant values. The stability of the combustion of a plant can thus be checked effectively. This time can be from the analyzer in the machine at a bidirectional interface for storage.
  • the joint processing of data in the analyzer can be used to identify critical boilers / burners Maps and how to avoid them by setting the Automatic burner controls / controllers are used. This prevents the thermodynamics between the burner flames and the boiler geometry Resonance phenomena with poorer combustion, strong noise and shortened Lifetime of the boiler due to mechanical stress.
  • Analysis values of the flue gas analyzer can be saved in the burner control or controller become. These values are used to determine the quality and opportunities for improvement Burner or a heating system is required and previous analysis values should also be be taken into account. By storing the values on site in the burner control or controller the paper protocols used today or the values stored in the analyzer are not needs more, which is advantageous because they are easily lost. The values can be changed at any time Plant can be accessed and are independent of a particular analyzer. A comparison The measured values of the chimney sweep with the last measured values of the service engineer can affect the quality improve your own measurements.
  • the joint processing of data in the analyzer can be used to determine the Flame time and flame intensity of the burner used to be at different Service corridors to be able to detect deviations / drift.
  • the flame formation time represents one important parameter when evaluating a burner. Based on the flame formation time and their scatter can determine the quality of the fuel mixing and ignition readiness. This measurement can be combined or supplemented with the next one Flame intensity and the additionally determined exhaust gas values when evaluating a burner or a boiler.
  • the flue gas analyzer can also be used as a replacement for existing parameterization devices for burners and boiler systems.
  • Existing boiler systems with integrated digital controllers require the parameterization of many individual parameters for optimal setting. Special tools are required today to set these parameters. However, these tools are complex and therefore also relatively expensive.
  • the parameterization tools for burners and boiler systems can be integrated into existing flue gas analyzers with sufficient display and control elements. This results in higher availability for the heating and service technician, since they only have to carry one instead of two service devices with them.
  • System parameters can also be saved in the existing customer databases of the flue gas analysis devices.
  • the parameter data and exhaust gas measurement values can thus be stored in a database in order to be able to carry out a better optimization. Such an optimization could show that a reduction in the min. Boiler output reduces the number of burner starts by 10%, or that by reducing the max. Boiler output the max. Exhaust temperature around 20 is lowered.
