Definitions

  • the present invention relates to a burner with a fiber based burner deck (burner surface), and with an improved flame measuring device by use of an ionization probe.
  • the invention further relates to a burner control system with more stable flame controllability over time.
  • an ionization signal which is obtained via an ionization electrode (ionization probe, ionization rod), is used in electronics to measure the presence of the flame and thereby also obtaining a measure for the air-gas ratio lambda.
  • Some methods aim at keeping the air-gas ratio constant, thereby obtaining clean combustion throughout the whole combustion range and/or with differing compositions of the combustion gas and/or with different composition and temperature of the combustion air.
  • An ionization system is generally comprising an electrode (or more than one electrode) and an earth, wherein a voltage is applied over the electrode and the earth. In some systems a further electrode might be the earth, in other systems the burner serves as earth.
  • DE 196 32 983 discloses a measuring device for a flame and an associated regulating device in a gas burner, wherein a lambda reference value for low emissions is set by means of an ionization electrode.
  • EP1154203 also uses a signal obtained by an ionization electrode which is located in the burner flame area as in DE 196 32 983 , but further improvements to the digitizing process are found.
  • EP1036984 discloses the use of an ionization electrode in a premix burner wherein the premix burner has locally an increased surface area of the mixture flow passages in order to obtain a representative linear signal throughout the whole working range of the premix burner. This increased surface area of the mixture flow passages is in the direct proximity of the ionization electrode.
  • WO2010/094673 A1 discloses a premix gas burner having a burner surface which exhibits a plurality of flow passages and at least two ionization electrodes connected to a measuring device and preferably also to a control device.
  • the ionization electrodes are arranged at different distances from the burner surface and the ionization electrodes are arranged electronically in parallel and electric currents are measured over each ionization electrode and the burner surface, the burner thus serving as earth in the electrical circuit.
  • US 4 900 245 discloses a premix gas burner according to the preamble of claim 1.
  • Burners with fiber based burner decks are known in the state of the art.
  • the fiber based burner deck is fixed to the supporting frame, plate or screen structure at the edges of the fiber based burner deck.
  • a common disadvantage of burners with fiber based burner deck is that over time or during use instability can exist in the combustion control.
  • the object of the present invention is to provide a burner with a burner deck made out of fiber based material and with improved burner control possibilities. It is a further object of the present invention to provide a burner control system which permits to control the air gas ratio of a burner in a stable way over the complete duration of a combustion process and over the life of the burner.
  • An aspect of the invention provides a burner according to claim 1.
  • the burner can have any shape as is known in the art.
  • One aspect of the invention relates to a burner with a burner deck having a curved surface.
  • Another aspect of the invention relates to a burner with a cylindrical shape (also called a cylindrical burner).
  • Yet another aspect of the invention relates to a burner with a conical.
  • the fixation of the burner deck near the ionization probe is present within a specific area of the burner deck.
  • This specific area of the burner deck is defined by the area around the vertical projection of the ionization probe onto the burner deck.
  • the specific area is defined by a distance of 35 mm around the vertical projection of the ionization probe onto the burner deck.
  • the specific area is defined by a distance of 25 mm around the vertical projection of the ionization probe onto the burner deck.
  • the specific area is defined by a distance of 20 mm around the vertical projection of the ionization probe onto the burner deck.
  • the burner deck can be a knitted fabric, a woven fabric or a nonwoven fabric.
  • the burner deck can also be made out of sintered fibrous material.
  • the fixation of the burner deck near the ionization probe can be via welding, glueing, stapling, riveting, stitching or in any other way that results in fixation of the burner deck near the ionization probe.
  • the fixation of the burner deck near the ionization probe can be via a combination of techniques resulting in fixation of the burner deck near the ionization probe.
  • fixations that fix the fiber based burner deck to the perforated plate or the screen near the ionization probe are 1 - 6 mm wide, preferably 2 - 4 mm wide.
  • the part of the burner deck that is not fixed to the perforated plate or the screen remains flexible.
  • the burner can be a premix gas burner.
  • Another aspect of the invention is a burner control system using a burner deck and ionization probe as described in the invention.
  • the measured current of the ionization probe is used to control the air-gas ratio lambda of the burner, thereby steering the combustion and guaranteeing proof of combustion in the way as set by the control parameters.
  • Another aspect of the invention is a heating apparatus comprising a burner as described in the invention.
  • Another aspect of the invention is a heating apparatus comprising a burner control system as defined in the invention.
  • Another aspect of the invention is the use of a burner as described in the invention.
  • a common disadvantage of state of the art burners with fiber based burner deck material is that due to its use (as an example due to thermal expansion) the burner deck will gain an offset to the perforated plate or screen that gives the burner deck its shape. As a consequence the distance of the burner deck to the ionization electrode (ionization probe, ionization rod) will change and hence the signal produced with such a setup will change as well. The change of the ionization signal over time during burning and over the lifetime of the burner is negative for a good and stable flame control. Furthermore, if the offset is amply, the distance to the ionization rod can become zero and an electrical shortcut will be the result.
  • One benefit of the invention is that it prevents the burner deck from changing its distance to the ionization probe during use of the burner and over the lifetime of the burner, resulting in a more reliable and stable ionization signal.
  • Another benefit of the fixation as described in the invention is that a better ground connection of the burner deck is realized, with enhanced ionization signal as a result.
  • Yet another benefit of the invention is that, at the positions where the burner deck is connected to the perforated plate or the screen, better flame stability is observed, resulting in a better ionization signal over a wider power range.
  • a burner 10 in figure 1 comprises an ionization probe 12 and a curved fiber based burner deck 14.
  • the curved fiber based burner deck 14 is supported by a perforated plate or a screen 16, providing the fiber based burner deck its curved shape.
  • the burner deck is fixed via point fixations 18 to the perforated plate or the screen 16.
  • the point fixations that fix the fiber based burner deck to the perforated plate or the screen near the ionization probe are 1 - 6 mm wide, in a more preferred embodiment 2 - 4 mm wide.
