Definitions

  • the invention relates to gas mixing blocks for ignition electrodes and for flame detection electrodes for gas burner systems.
  • the invention relates more specifically to the field of infrared radiation gas burner systems as are e.g. used in infrared drying of sheet like material such paper, board or coatings on metal sheets. In such radiation gas burner systems, ignition electrodes and flame detection electrodes are used.
  • the invention relates to such electrodes that operate on a supply of premix gas, premixed using a gas mixing block.
  • the invention further relates to ignition electrodes, to flame detection electrodes and to methods of using the electrodes in gas fired infrared drying or curing systems, e.g. in such continuous systems.
  • electrodes are used to detect the presence of combustion of gas by the gas burners.
  • a commonly used type of electrode comprises a gas supply (which is a premix of combustible gas and air) in a tubular supply in the electrode, and two electrical conductors. The premix of combustible gas and air is prepared in a mixing block.
  • the flame detection electrode is positioned close to the infrared gas burner. If combustion of gas occurs at the infrared radiation gas burners, a flame is present at the infrared radiation gas burner. Via contact propagation, a flame will be generated in the gas supplied to the flame detection electrode. The flame will close an electrical circuit between the two electrical conductors of the electrode.
  • An electrical current - the ionization current - is generated.
  • the presence of the ionization current indicates the presence of combustion at the gas burner, absence of the electrical current indicates absence of combustion at the gas burner.
  • the electrodes serve as safety devices: if no flame is present at the gas burners, the electrodes detect it and shut off the gas supply to the gas burners. Flame detection electrodes are continuously supplied with premix gas during the operation of the radiation gas burners in order to have a continuous monitoring of the presence of combustion on the radiation gas burners when combustible gas is supplied to them.
  • Ignition electrodes - electrodes to ignite the gas premix supplied to the infrared radiation gas burners - can be similar as the flame detection electrodes. Gas is mixed with air in a mixing block and the premix is sent through a tube. A voltage is applied between two electrical conductors, generating a spark that ignites the gas between the two electrical conductors. The flame of the ignition electrode ignites via contact propagation the infrared radiation gas burner near to which it is located. Flame detection electrodes will detect that the infrared radiation gas burners have been ignited and premix gas supply to the ignition electrodes will be shut off.
  • the premix of combustible gas and air is made close to where the premix is to be burnt. It means that the flame detection electrodes and/or the ignition electrodes are supplied by another (and separate) premixing unit or mixing block than the infrared radiation gas burners.
  • the premixing unit the combustible gas is entered at a certain pressure through an injector and air is supplied and combustible gas and air are mixed.
  • the premix parameters have to be set right and in tight control.
  • Infrared radiation gas burner systems exist that can operate on different types of combustible gas, e.g. on natural gas, on propane, on butane...
  • the gas supply system to such infrared radiation gas burner system is adapted in such a way that a mere change of the gas supply (feed other gas to the supply line) and setting of the appropriate gas pressure and air supply pressure suffices to obtain correct premixing.
  • this approach does not work properly for the gas supply to the flame detection electrodes and to the ignition electrodes.
  • the premixing unit of each of the flame detection or ignition electrodes of the infrared radiation gas burner system has to be adapted and tuned manually, e.g. exchange and tuning of injector, exchange and tuning of diaphragm, setting of gas and/or air pressure.
  • infrared radiation gas burner systems can - dispersed over their surface - comprise a large number of ignition and flame detection electrodes (each with a separate mixing block), such adaptations are time consuming and costly.
  • the tuning has to be done in a precise way. Due to the vulnerability of the electrodes (especially of the flame detection electrodes as these are in continuous operation during operation of the infrared radiation gas burners), incorrect adaptation of the flame detection electrodes when changing gas supply results in reduced lifetime of the flame detection electrodes.
  • a first aspect of the invention is a mixing block for preparing a premix of combustible gas and air to be supplied to a flame detection electrode or to an ignition electrode.
  • the mixing block comprises
  • the switch comprises a flow channel inside it.
  • the flow channel in the switch is positioned in such a way to create gas flow connection between one of the at least two connections and the outlet channel.
  • the switch can e.g. be mounted rotatable in the mixing block, so that by rotation of the switch, the flow channel in the switch is positioned in such a way to create gas flow connection between one of the at least two connections and the outlet channel.
  • the mixing block when the mixing block is in use, the premix of combustible gas and air is created in the mixing block after the flow of combustible gas has passed the switch. In this embodiment, it is possible to equip the mixing block with one air inlet only, resulting in a more simple construction of the mixing block. In another preferred embodiment, when the mixing block is in use, the premix of combustible gas and air is created in the mixing block before the flow of combustible gas has passed the switch. In this embodiment, it is recommended to equip the mixing block with separate air inlets for each of the combustible gas supply connections. This allows to optimally define the air inlets (e.g.
  • the switch can be operated manually.
  • the switch can be operated via a control system.
  • means are provided for setting the pressure of at least one of the combustible gas supplies, preferably for each of the combustible gas supplies; and/or of the air supply.
  • means are provided for setting the flow rate of the supply of the air that is used to create the premix of combustible gas and air; and/or of at least one of the combustible gas supplies, preferably for each of the combustible gas supplies.

  • a different combustible gas type e.g. one for natural gas and one for propane.
  • the mixing block comprises the same number of air inlets as the number of combustible gas inlet connections.
  • Each of the air inlet can be provided with appropriate parts and/or appropriate settings for the combustible gas type towards which they can supply air, e.g. the air inlets can be provided with appropriate diaphragms so that the correct air flow will be supplied for the gas flow of the combustible gas type with which the air inlet is paired.
  • the mixing block comprises one air inlet, preferably only one air inlet.
  • a second aspect of the invention is a flame detection electrode for use in infrared radiation gas burner systems, comprising

  • a fourth aspect of the invention are gas fired infrared emitter systems comprising one or more flame detection electrodes comprising a mixing block of the first aspect of the invention and/or comprising one or more ignition electrodes comprising the mixing block of the first aspect of the invention.
  • the system is equipped with a fan and air channels for the supply of air to the mixing block via the at least one inlet for supplying air into said mixing block.
  • a first connection of the mixing block is connected to a supply of a first type of combustible gas; and a second connection of the mixing block is connected to a supply of a second type of combustible gas.
  • a fifth aspect of the invention is a method for changing over combustible gas supply in a mixing block, wherein a mixing block is used as in the first aspect of the invention and wherein the switch is actuated to select the combustible gas supply between the at least two connections at the mixing block.
  • the change-over of combustible gas is performed without modifying settings in the mixing block besides the actuation of the switch and without exchanging parts in the mixing block.
  • a sixth aspect of the invention is a method of operating a gas fired infrared emitter system as in the fourth aspect of the invention, wherein the gas fired infrared emitters of the gas fired infrared emitter system can be operated on two or more types of combustible gas.
  • the switches of the mixing blocks are actuated in order to change over the combustible gas supply to the mixing blocks of the electrodes, for operation of the gas fired infrared emitters and the electrodes on the same type of combustible gas as the gas fired infrared emitters.
  • the change-over of combustible gas is performed without having to modify settings in the mixing block besides the actuation of the switch and without having to exchange parts in the mixing block.
  • the gas fired infrared emitter systems are provided in continuous drying or curing installations, e.g. for the continuous treatment of web like material, such as paper, board or metal strip.
  • Figures 1 and 2 shows an electrode as can be used in the invention as detection electrode or as ignition electrode.

  • the electrode 120 comprises a tube 130 through which a premix of combustible gas (e.g. natural gas, e.g. propane gas) with air is supplied.
  • the tube 130 can be made out of electrically conductive material, e.g. Inconel, or the tube 130 can have a ribbon like section made out of electrically conductive material at the inside of the tube 130.
