Definitions

  • the invention relates to a power plant combustion system with a large number of parallel-acting burners arranged in a wall of a combustion chamber and supplied with combustion air via a common windbox, the combustion air being supplied to each individual burner via one or more annular gap (s) concentrically surrounding the burner.
  • a large number of burners are usually arranged, acting in parallel, in a wall of a combustion chamber and are supplied with combustion air via a common wind box.
  • the combustion air is preferably supplied to the individual burner via one or more annular gaps concentrically surrounding the burner.
  • the supply of the combustion air to the annular gap comprises means in order to influence the amount of combustion air flowing through the annular gap and subsequently into the combustion chamber.
  • air guide devices such as guide vanes, are arranged in order to introduce the combustion air into the combustion chamber in a spiral as a swirling flow around a flame that forms in front of the burner, with the flow direction of the combustion air flow being changed the position of the guide vanes can be changed.
  • both the means for influencing the amount of combustion air flowing through the annular gap and subsequently into the combustion chamber and the air guiding devices, for example guide vanes, can be designed differently and separately controllable in each annular gap.
  • the combustion air for the main and post-combustion can be introduced separately into the combustion chamber in front of a single burner, ie in different combustion zones of the flame in the direction of flow and the amount of combustion air.
  • the guide vanes for generating a swirling flow of the combustion air flow and the means for influencing the amount of combustion air can be integrated as actuators in a control device for controlling the combustion process, so that the combustion process can be controlled separately for each individual burner of a power plant combustion system.
  • a control device for controlling the combustion process so that the combustion process can be controlled separately for each individual burner of a power plant combustion system.
  • dynamic pressure probes of this type cannot be used for measuring the speed of the combustion air flow in the annular gap of combustion air feeds to a burner in a power plant combustion system, because the flow of the combustion air in the annular gap is extremely turbulent and possibly shows a swirl with strongly curved flow lines, so that a dynamic pressure probe can be used only a directed speed of the combustion air flow can be determined if the combustion air flow hits the probe perpendicularly.
  • a turbulent flow and the combustion air flow not perpendicularly impinging on the dynamic pressure probe in particular if the direction of the combustion air flow changes, no directional velocity of the combustion air flow can be determined from the differential pressure determined by the dynamic pressure probe.
  • a determination of the amount of combustion air flowing through an annular gap is therefore not possible by means of dynamic pressure probes arranged in the annular gap.
  • the combustion air in a coal-fired power plant is heavily loaded with ash particles, which leads to rapid contamination of the pitot tubes. The solution is therefore not applicable for an optimized control of the combustion process in a power plant combustion system.
  • a sensor device for determining the one or a group of burners of a burner arrangement with a common combustion air supply via a windbox is known according to the cross-correlation measurement method, in which within the windbox, each spanning the flow cross-section of the windbox, sensor arrangements are arranged so that the each around the a burner or a group of burners supplied combustion air quantity reduced combustion air flow flows through the sensor arrangements.
  • a sensor arrangement consists of two individual sensor rods or sensor rod groups that span the cross section of the wind box, one behind the other in the direction of flow of the combustion air stream, spaced apart from one another and arranged crossing one another.
  • Correlation methods are used to determine the speed of the combustion air flow from the signals generated on the sensor rods as a result of electrical influence caused by electrically charged particles flying past the sensor rods and transported in the combustion air flow. Based on the speed of the combustion air flow and the associated geometry of the wind box, the amount of combustion air flowing through the wind box can be calculated.
  • the amount of combustion air supplied to an individual burner can, however, only be determined with this device in the case of special arrangements of burners in connection with a specially designed windbox. Such arrangements of burners and designs of a windbox are of little importance in practice.
  • this solution has the disadvantage that the measurements that refer to one another can have a considerable measurement error due to error propagation.
  • This solution is also for an optimized control of the combustion process in a power plant combustion system is not suitable.
  • a device and a method for controlling the fuel-air ratio during the combustion of ground coal in a coal-fired power plant are known, in which the combustion air quantity measurement and the support air quantity measurement according to the correlation method by evaluating electrical signals that are obtained by means of sensors arranged in the air flow are carried out .
  • two sensor rods are arranged one behind the other in the air flow direction in the air-conducting channel, in which electrical signals are generated by electrical induction, which is caused by electrically charged particles moving past the sensor rods in the air flow, which are fed to a correlation measuring device.
  • the correlation measurement method is used to determine the time that the electrically charged particles need to overcome the distance between the two sensor rods.
  • the flow speed of the air stream is calculated from the time and the distance between the sensor rods and the air volume is calculated based on the geometry of the air-carrying duct.
