Definitions

  • the invention relates to a method for commissioning a heating device, a control device, a heating device and a computer program.
  • a large number of heating devices which burn a mixture of a fuel, in particular gas or hydrogen, and ambient air in a combustion chamber in order to generate heat to supply a building or to provide hot water.
  • a conveyor is usually started up to a target output and fuel is added to a conveyed volume flow of intake combustion air.
  • the combustion mixture formed is fed to a burner of the heater and ignited by an ignition device, for example a spark or glow igniter.
  • an ignition device for example a spark or glow igniter.
  • the gas supply is usually operated with an ignition ramp during an ignition process, whereby a largely constant mass flow of combustion air is fed with a mass flow of fuel gas that increases from a start value to an end value within a safety period.
  • the safety period is selected so that the escape of a critical (unburned) amount of fuel gas at the burner during an ignition process can be safely avoided.
  • the ignition ramp ensures that suitable starting conditions are set for different types of gas (for example, from a gas family) during an ignition process.
  • gas for example, from a gas family
  • heaters with a variety of gas types, which can result in very steep ignition ramps with a high gradient of the mass flow of fuel gas to be supplied.
  • the associated short dwell times of a mixture composition can make ignition difficult during an ignition process. If the supplied combustion mixture cannot form a flame during an ignition process within a safety period, the start attempt is aborted.
  • Changing ignition conditions such as a modulation point of the heater that needs to be approached during the ignition process or operating parameters of the heater, can have a significant impact on the ignition process. Problems during the ignition process can lead to unwanted noise and, if more severe, can also cause damage to the heater.
  • the EP 3 301 365 A1 proposes a method for controlling the ignition of a heater, in which an operating characteristic value recorded before the ignition is taken into account.
  • the operating characteristic value can be suitable for representing a quality, type or calorific value of the fuel and/or a performance requirement for the heater.
  • the proposed method is very complex, in particular the determination and consideration of the operating characteristic value must be tailored to the heater and is therefore prone to errors.
  • the EN 10 2004 058 087 A1 describes a method for starting the burner of a gas heater, which takes environmental conditions into account. However, complex sensors are required to record the environmental conditions.
  • the object of the invention is to propose a method for starting up a heater which at least partially overcomes the problems of the prior art described.
  • a particularly simple and universally applicable method is to be proposed which enables a heater to be safely ignited even when the operating and environmental conditions of the heater change.
  • Steps a), b) and c) can be carried out at least once in the specified order when carrying out the procedure regularly.
  • steps a) to c) can be carried out each time the heater is started up.
  • the procedure serves to ensure a safe ignition process or safe start-up of a heater and can in particular help to reduce noise during the ignition process and prevent damage to the heater.
  • the heating device can comprise at least one heat generator, in particular a gas condensing boiler, which releases heat energy by burning a fuel and can transfer it to a heating circuit via at least one heat exchanger, whereby consumers of the heating circuit can be connected to the heating device via a heating flow and a heating return of the heating circuit.
  • the heating circuit can comprise a circulation pump, which can be set up to circulate a heat transfer medium (heating water) in the heating circuit, whereby heat transfer medium heated via a heating flow can be supplied to consumers, such as convectors or surface heating systems, and returned to the heat generator or the at least one heat exchanger via the heating return. Exhaust gases generated during combustion can be discharged to the outside via an exhaust duct of the heating device and a subsequent exhaust system.
  • the heater can also have a flame monitor.
  • An ionization electrode is often used for this purpose, which can use an ionization current from the flame to detect it.
  • this principle cannot be used robustly with a hydrogen flame, since significantly fewer free charge carriers are produced when hydrogen is burned.
  • Other methods are therefore often used with hydrogen-powered heaters, such as detecting the electromagnetic radiation emitted by the flame, in particular infrared (IR) and/or UV (ultraviolet) radiation, or detecting the flame temperature.
  • IR infrared
  • UV ultraviolet
  • the heating device can also have an ignition device which is arranged on the burner in such a way that combustion mixture emerging from the burner can be ignited.
  • the ignition device can in particular be an electrical ignition device whose output can be controlled electrically.
  • the ignition device can in particular be a spark igniter, whereby the intensity of the ignition spark formed can be adjusted by the applied electrical power.
  • the intensity of the ignition spark, and thus the (electrical) power of the ignition device, can significantly influence the ignition process.
  • the electrical power can be adjusted, for example, by an ignition voltage.
  • the ignition device can be a hot surface igniter, which can be heated electrically to a surface temperature above the ignition temperature of the combustion mixture.
  • the electrical power of a hot surface igniter can be used to adjust its surface temperature and thus the ignition conditions of the combustion mixture at the burner.
  • Commissioning of a heater can proceed as follows. Firstly, for example, a control device of the heater can start up a conveyor system, which is usually designed as a fan, to a predetermined starting power or starting speed. Then, after the starting power or starting speed has been reached, a mass flow of fuel predetermined for the starting speed can be supplied and an ignition process can be initiated by commissioning the ignition device with a predetermined power.
  • the predetermined mass flow of fuel can in particular be specified as a range that maps different gas types and ignition conditions and can therefore enable a safe ignition process for different gas types and/or ignition conditions.
  • the range of the mass flow of fuel gas can be mapped by an ignition ramp within the safety period.
  • the ignition ramp can define a functional relationship between time and the mass flow of fuel gas to be supplied, whereby the ignition ramp must be regularly run through within a safety period of the ignition process.
  • the safety period is selected so that if a flame does not form on the burner during an ignition process, no critical amount of unburned fuel (fuel gas) escapes, and is often in the range of 3 to 5 seconds. Since the safety period cannot be extended for reasons of operational safety, the entire ignition ramp must be run through within the safety period, which can lead to high rates of change in the mass flow of fuel gas during an ignition process.
  • the functional relationship also known as the ramp function, is usually a linear function that increases from a starting mass flow to a final mass flow.
  • a stabilization time can then define a period of time in which a flame that has formed can stabilize before the heater can switch to free modulation following the ignition process. The stabilization time is often in the range of 2 to 5 seconds, although environmental conditions may also be taken into account.
  • a ramp function can be given, for example, by a starting point v ⁇ 0 at time to and an end point v ⁇ 1 at time t 1.
  • a volume flow v ⁇ S can be set for the subsequent stabilization period, formed by adding an increase in the volume flow v ⁇ Ü to the volume flow of fuel gas at the time of the appearance of the flame v ⁇ ( t F ), which can be kept constant for
  • step a) at least one location-specific environmental parameter retrieved from a network and/or a status parameter of the heater can be recorded.
  • a location-specific environmental parameter can in particular indicate environmental conditions at the location of the heater, such as air pressure, outside temperature, geodetic altitude (above sea level), wind speed and/or humidity of the ambient air.
  • environmental conditions at the location of the heater such as air pressure, outside temperature, geodetic altitude (above sea level), wind speed and/or humidity of the ambient air.
  • a storm warning could be an environmental condition to be recorded.
  • a state parameter can be a parameter that describes or indicates a state of the heater.
  • An example of this can be a temperature of the heater, in particular a temperature in the combustion chamber, which significantly influences the ignition conditions.
  • Other examples of state parameters of the heater can be a temperature of the heater flow and/or the heater return.
  • a detection according to step a) can be carried out by measuring a parameter, for example by a control device of the heater.
  • the detection of a location-specific environmental parameter takes place via a network, in particular via the Internet.
  • a control device of the heater can be connected to be connected to a network for exchanging data.
  • existing smart home devices can be used to query location-specific environmental parameters.
  • measuring devices smart metering devices
  • measuring devices smart metering devices
  • a smart home device could also provide information on environmental conditions or on the fuel supplied (quality, pressure, energy content, temperature).
  • the ignition ramp function can be adapted to the ambient parameters and/or status parameters of the heater recorded in step a).
  • the adaptation can relate to both the ignition ramp function, in particular its rise and offset, as well as a subsequent stabilization time.
  • the ramp function can be adapted based on a recorded location-specific ambient parameter or a recorded status parameter, whereby the stabilization time can also be adapted.
  • An extension of the stabilization time can seem sensible, for example, in the case of high wind speeds or a storm warning.
  • the ignition ramp can be adapted to several environmental or state parameters separately and one after the other. This allows a very specific and precise adaptation of the ignition ramp to the current ignition conditions.
  • a diagnostic parameter that allows a conclusion to be drawn about the ignition process can be recorded and evaluated during the ignition process.
  • the diagnostic parameter can be a parameter that allows a conclusion to be drawn about a pressure curve in the flow path (combustion air supply, fuel gas supply, mixture channel, exhaust pipe or system) of the heater, for example a volume or mass flow sensor in the combustion air supply or in the mixture channel, and/or a signal from the conveyor device, in particular a speed signal or a control signal from a speed controller of the conveyor.

  • the reference values or characteristic maps can have been determined in advance using laboratory tests on a reference heater.
  • the evaluation of an ignition process from step d) can be included in the adaptation of the ignition ramp in step b).
  • the heater can be put into an error state in which restarting is blocked or can only be carried out by a qualified person.
  • a critical ignition process can be detected, for example, by exceeding a pressure limit in the gas supply to the heater or by a lack of or insufficient flame formation.
  • information about a result of an evaluation of the ignition process, a recognized critical ignition process or about the heater entering a fault state can be displayed via a display device (external or integrated into the heater) and/or made available for retrieval via a network, in particular the Internet, and/or sent as a message.
