Definitions

  • the present invention relates to a method and a device for controlling a combustion process in a boiler according to the preamble of claim 1 and claim 10.
  • Interventions on actuators of the combustion process are derived as a function of the measured variables, so that, for example, at a high NOx concentration in the combustion gas, actuators of the burner are actuated in order to supply higher amounts of combustion air globally.
  • the fuel supply can be increased by correspondingly actuating actuators.
  • a stable control of the combustion process with the known methods is relatively difficult due to several parameters that have to be observed simultaneously.
  • the known methods have the disadvantage that they do not record the actual combustion process of the fuel and only control it indirectly.
  • the object of the present invention is to provide a method and a device for controlling a combustion process in a boiler according to the preamble of claim 1 and claim 10, respectively, which allows direct detection and control of the combustion.
  • the detector advantageously detects the flame by means of a high-resolution and low-spectral resolution sensor and a low-resolution and high-spectral resolution sensor.
  • the high-location and low-spectral resolution sensor is preferably designed as a CCD camera. With the CCD camera, the shape and surroundings of the flame can be easily captured. This sensor preferably detects the flow field of the flame. It can also detect a relatively accurate local distribution of the temperature.
  • the low-location and high-spectral resolution sensor is preferably formed by glass fiber cables with associated spectral decomposition devices.
  • a spectral decomposition device can be designed in a particularly simple manner as a grating, slit or prism.
  • the radical and / or temperature field of the flame is preferably detected with the low-resolution and high-spectral resolution sensor. The detection of individual radicals is of particular importance and their precise local assignment is of lesser importance.
  • changes in the temperature, flow and / or radical field of the flame are preferably recorded over time.
  • Fig. 1 shows schematically a section of a boiler for coal combustion.
  • FIG. 2 shows a view of the detector from FIG. 1.
  • the boiler 1 for coal combustion shown schematically in FIG. 1 has a burner 2. Fuel and air are introduced into the boiler 1 via the burner 2 and burned to form a flame 3.
  • the essentially cylindrical burner 2 comprises an outer air duct 4, an inner air duct 5 and an inlet duct 6 for the introduction of fuel.
  • An entry funnel 7 is provided at the end of the burner 2 facing the boiler 1.
  • a detector 10 connected to a computing device 9 is received from a wall 8 of the boiler 1.
  • the detector 10 is directed towards the flame 3 and comprises a sensor which is designed as a CCD camera 11 and which has a high-location and low-spectral resolution and a sensor which has a low-location and high spectral resolution and is formed by fiber optic cable 12 with associated spectral decomposition devices.
  • the glass fiber cables 12 of the sensor are arranged below the lens of the CCD camera 11.
  • the computing device 9 is connected to actuators of the burner 2 and a fuel mill (not shown) via signal lines (not shown).
  • the glass fiber cables 12 are arranged in a fan-like manner.
  • the flame 3 formed in the coal combustion is observed by the detector 10 and its formation is detected.
  • the shape and the flow field are detected by the sensor 11 and the radical and temperature field of the flame 3 are detected by the sensor 12.
  • the output signals of the detector 10 are forwarded to the computing device 9 and processed there to control signals for the actuators of the burner 2 and the fuel mill for regulating the flame 3.
