Definitions

  • the invention relates to a method for starting a heater, a computer program, a control device and a heater.
  • a start-up process in particular can trigger critical conditions.
  • critical conditions can be hard ignition, a deflagration or a flashback, i.e. a flame spread during a start-up or ignition process from the burner into a feed line for the mixture of fuel gas and combustion air, which can lead to damage to the heater.
  • hydrogen is used as the fuel gas
  • critical conditions are more likely because the volatility and low density of hydrogen means that the start-up process repeats significantly less well.
  • the first start-up of a cold heater can be particularly difficult because a gas flow that diffused out of the gas flow valve while the burner was not in use must first form again at the gas control valve.
  • the EP 3 992 529 A1 It is proposed to use a pilot flame with its own fuel supply to ignite a main burner, the function of which can be monitored by a sensor and which is also arranged in such a way that the pilot flame cannot be extinguished by air escaping from the main burner.
  • a pilot flame with its own fuel supply to ignite a main burner, the function of which can be monitored by a sensor and which is also arranged in such a way that the pilot flame cannot be extinguished by air escaping from the main burner.
  • the object of the invention is to propose a method for starting a heater, a computer program, a control and regulating device and a heater which at least partially overcome the problems of the prior art described.
  • the invention is intended to enable a successful first ignition process of a heater, in particular a heater operated with hydrogen.
  • the method should be suitable for being carried out at least partially automatically and require as few structural changes as possible compared to a state-of-the-art heating device.
  • a method for starting a heating device contributes to this, wherein the heating device has at least one conveying device for conveying a combustion mixture of fuel gas and combustion air to a burner, an ignition device for the combustion mixture and a gas valve, wherein before starting the conveying device, the gas valve is opened briefly, whereby the gas valve is filled with fuel gas.
  • the method can be carried out in particular during each start-up process, and if necessary also when commissioning the heater.
  • the method is used in particular for a safe and successful first ignition process of a heater, in particular a heater operated with hydrogen or a mixture containing hydrogen as fuel.
  • a time delay caused by a longer period of interruption of burner operation from the opening of the gas valve to the onset and stabilization of the volume flow of fuel gas can be reduced or avoided.
  • 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, wherein consumers of the heating circuit can be connected to the heating device via a flow and a return.
  • the exhaust gases produced during combustion can be fed to an exhaust system via an exhaust duct of the heating device.
  • a circulation pump can be set up in the heating circuit to circulate a heat transfer medium (heating water), wherein heat transfer medium heated via a heating flow can be fed to consumers, such as convectors or surface heating systems, and can be returned to the heat generator or the at least one heat exchanger via a heating return.
  • the heating device can have a conveying device, in particular a fan, which feeds a mixture of combustion air and fuel (hydrogen) to a burner of the heater.
  • the conveying device can comprise a power control, in particular a speed controller.
  • the gas valve can comprise a gas safety valve that only opens under defined safety-relevant conditions, for example an activated ignition device of the heater.
  • the gas valve can also comprise a gas control valve that is designed to control a mass flow of fuel gas to be supplied and thus the combustion air ratio.
  • the gas valve can also have a pressure regulator that sets a constant pressure of the fuel gas at the gas control valve and can thus compensate for pressure fluctuations in the gas supply.
  • the heater can in particular form a pneumatic gas-air connection (pneumatic mixture formation) in which a mass flow of combustion air provided via a gas supply is added to a mass flow of combustion air in accordance with a negative pressure (control pressure) of a throttle point, such as a Venturi nozzle, in the combustion air supply, so that a predefined (specified) combustion air ratio (air ratio, lambda) can be established.
  • the control pressure as a measure of the inflowing mass flow of combustion air, can suck a mass flow of combustion gas out of the gas control valve.
  • a gas valve of this type is also referred to as a pneumatic gas valve.
  • the heater may alternatively have an electronic gas-air connection, in which a signal from a flame monitor or an exhaust gas monitor (for example using a lambda sensor, a conclusion can be drawn about the flames and the combustion air ratio (also known as lambda or air ratio), so that it can be regulated.
  • a control system can determine and set an opening width of the gas valve in order to approximate a desired combustion air ratio derived from the signal to a target combustion air ratio.
  • the gas valve can set an opening width according to the required mass flow of fuel gas, often using an electronically controlled stepper motor.
  • the heating device can be designed in particular to burn hydrogen as a fuel or a mixture containing hydrogen.
  • the fuel mixture can have a hydrogen content of at least 80% or at least 90%.
  • 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 heater can be started as follows. First, a control unit of the heater, for example, can start a conveyor device, which is usually designed as a fan, to a specified starting power or starting speed. Connect After the starting power or starting speed has been reached, a mass flow of fuel predetermined for the starting speed can be fed in and the ignition device can be put into operation. If no flame formation is detected by the flame monitoring system after a safety time has elapsed, the start-up attempt is terminated and the gas valve is closed. The feed device can then blow out any fuel gas that may have remained in the mixture channel or combustion chamber for a (regular) purging period before a new start-up attempt can be made.
  • a control unit of the heater for example, can start a conveyor device, which is usually designed as a fan, to a specified starting power or starting speed. Connect After the starting power or starting speed has been reached, a mass flow of fuel predetermined for the starting speed can be fed in and the ignition device can be put into operation. If no flame formation is detected by the flame monitoring system
  • the necessary duration of a (regular) purging period is often 5 seconds [s] to 10 seconds [s] and can, for example, be determined empirically depending on the starting speed and the volumes to be purged.
  • the safety time can be dimensioned such that the amount of energy supplied by the fuel gas is limited in such a way that damage to the heater can be prevented in the event of a misfire.
  • the mass flow of fuel gas specified for the starting speed can be adjusted using the control pressure of the throttle point in a pneumatic gas-air system and electronically controlled in an electronic gas-air system.
  • the heater can also have an ignition device that can ignite the combustion mixture emerging from the burner.
  • the ignition device can, for example, comprise a spark or glow igniter or even a pilot flame.
  • the gas valve should be opened briefly (immediately) before the delivery device is activated, allowing the gas valve to fill with fuel gas.
  • a start instruction to the heater initially prevents the activation of the delivery device until the gas valve is safely closed again after the brief opening. found that the problematic time delay between opening the gas valve and the onset and stabilization of the mass flow of fuel gas can be significantly reduced.
  • the gas control valve can also work faster and more precisely.
  • a short-term opening refers to a period of opening that is sufficient for the gas valve to fill with fuel gas. No or only a very small amount of fuel gas should be able to escape into the flow path or mixture channel of the heater.
  • the corresponding period can be determined, for example, using a reference heater and can be in a range of 0.5 seconds to 3 seconds. In any case, the period of short-term opening should not exceed the safety time of an ignition process of the heater and in particular should be less than half the safety time.
  • the period of brief opening can be such that the gas valve and pressure regulator can fill with fuel gas.
  • a negative offset value can be set on the gas valve during the brief opening of the gas valve.
  • the offset value here refers to a zero point shift in the opening width of the gas valve.
  • a mass flow of combustion air in the combustion air supply can be detected (immediately) before the gas valve is briefly opened. This can be done in particular by means of a flow sensor, whereby the detected values stored in a memory, for example in the control unit.
  • the recorded mass flow of combustion air can be compared with a limit value.
  • the brief opening of the gas valve can be authorized if the recorded mass flow is below the limit value.
  • a mass flow of combustion air can form, for example, due to gusts of wind at the intake of the combustion air or in the area of an outlet of the exhaust system of the heater.
  • the brief opening of the gas valve can be delayed or not carried out. The delay could take place until a mass flow of combustion air below the limit value is detected.
  • the heater could be started up without briefly opening the gas valve before the conveyor is started up. The same could happen if a mass flow of combustion air greater than a limit period is detected.
  • the limit period can be selected accordingly; for example, 2, 5 or 10 seconds could seem sensible here.
  • the conveying device can be put into operation after the gas valve has been briefly opened and any fuel remaining in the flow path of the heater can be removed in a shortened flushing period.
  • the flushing period after the gas valve has been briefly opened can be significantly shortened, since only very small amounts of fuel are released during the short-term opening of the gas valve. Quantities of fuel gas may leak into the heater's flow path, which must be removed during the purge period.
  • the reduced purge time may be less than half or less than one third of the regular purge time, for example in a range of 2 seconds to 5 seconds. The heater may then perform a regular start-up attempt.
  • the ignition device of the heater can be put into operation during the brief opening of the gas valve. This can increase safety, since ignitable combustion mixture escaping from the burner due to the brief opening may be burned. This undesirable circumstance would be relevant to safety and could be detected by flame monitoring of the heater. If a flame is detected during the brief opening, the heater could go into an error state or suspend the implementation of a method proposed here and provide information on this, for example via a display device or a network.
  • a duration of the (last) interruption of burner operation can be recorded and the duration of the short-term interruption can be adapted to the recorded duration of the (last) interruption of burner operation. For example, if the duration of the interruption is less than 5 to 10 minutes, the gas valve could not be opened briefly, since only small amounts of fuel gas can have evaporated from the gas valve during this period.
  • a mass flow (combustion air, fuel or a mixture of both) can also characterize a volume flow and vice versa.
  • a mass flow can easily be converted into a volume flow and vice versa if the density and temperature of the medium are known.
  • a computer program is also proposed which is set up to (at least partially) carry out a method presented here.
  • this relates in particular to a computer program (product) comprising commands which, when the program is executed by a computer, cause the computer to carry out a method proposed here.
  • the computer program can in particular be executed on a control and regulating device of the heating device.
  • a machine-readable storage medium is also proposed on which the computer program is stored.
  • the machine-readable storage medium is usually a computer-readable data storage device.
  • a control device for a heating device is also proposed, set up to carry out a method proposed here.
  • the control device can for example have a processor for this purpose and/or have one.
  • the processor can for example carry out the method stored in a memory (of the control device).
  • the control device can in particular be electrically connected to the conveyor device, the gas valve and the flame monitor.
  • Relevant data for carrying out a method proposed here can be stored in a memory of the control device, for example a duration of the brief opening of the gas valve and/or a limit value of the recorded mass flow of combustion air.
  • a heating device having a regulating and control device as proposed here.
  • the heating device can be a gas heating device, in particular a hydrogen-operated gas heating device.
  • the gas heating device can have a burner, a conveying device and a gas valve, wherein the conveying device can supply a combustion mixture of fuel gas (hydrogen) and combustion air to the burner.
