Definitions

  • the invention relates to a method for detecting and assessing ignition problems after the preliminary parts of the independent procedural claims as well as on a device for carrying out the method.
  • a method for detecting and assessing ignition problems after the preliminary parts of the independent procedural claims as well as on a device for carrying out the method.
  • Such a method is known for example from JP 07 119 965.
  • the aim of the invention is to avoid this disadvantage and a method of the aforementioned Kind of suggesting that a clear conclusion on the condition of the burner allows or makes it possible to distinguish whether the ignition problems by a deteriorated condition of the burner or problems in controlling the ignition are conditional.
  • the frequency determined by those cases in which there are a certain number of ignition attempts needed until the burner could be successfully ignited If the number of cases increases in which required more than one ignition attempt, in relation to those cases in which already the first ignition attempt after a start command for the burner was successful, Slowly, this is an indication of deterioration due to wear Condition of the burner. If this ratio changes essentially abruptly, then so This is an indication of problems with the control of the ignition or the gas supply.
  • the same target may also be used according to the other alternative claim two can be achieved by detecting the number of unsuccessful attempts at ignition. advantage This method is that the counters can have lower capacity.
  • Claim three describes a method according to the invention, in which the number of unsuccessful Ignition attempts in relation to the total number of ignition attempts is set, which the number of switching operations of the gas burner is taken into account.
  • Another object of the invention is to provide a device for carrying out the invention Propose procedure.
  • a fuel-fired heater is shown, be it a water heater for sanitary purposes, a circulating water heater, a boiler, a storage or a space heater.
  • This heater 20 has a controller 1, which is assigned an ignition circuit 2 is, which is connected via a line 11 with an ignition electrode 21, the one Gas or oil burner 3 is assigned, which is provided with a solenoid valve 22 via a Fuel line 23 is supplied with gas or oil.
  • the burner 3 is associated with a heat exchanger 24 which is connected to an exhaust gas collecting hood 25 is provided, which merges into a flue 26.
  • the burner is a monitoring electrode 27, which is connected by means of a line 12 to the controller 1.
  • a flame detection circuit 4 connected to the line 12 is.
  • the controller 1 includes counters 5, 6 and 7, which are connected to a memory 8. Of the Memory 8 is provided via an interface 9 with a display 10 for the memory contents.
  • the controller 1 also includes a timer 29, in which a safety time specified can be. If no flame formation is achieved within this safety period, a closure of the gas valve and after flushing the combustion chamber is a renewed Ignition test for the burner. After a certain number of futile attempts at ignition there is an interlocking shutdown, i. Closing the solenoid valve 22, which can only be lifted again by a manual intervention.
  • a processor 28 provided in the controller 1 operates a program stored in the memory 8 and controls u.a. the ignition circuit 2 and this the ignition electrode 21 of the burner 3. Will within the safety time after the ignition command sufficient flame formation via the ionization path between the electrodes 21 and 27 from the flame detection circuit 4, that is, the ignition attempt was successful, the counter becomes 5 increments.
  • the counter 5 indicates the number of cases in which already the first attempt at ignition was successful. In an optimal operation, therefore, the counters 6 and 7, which remain the Indicate the number of cases in which two or three attempts at ignition were required on the Value zero.
  • the processor 1 works Program, which he retrieves from the memory 8, from.
  • the number of cases where two attempts at ignition until successful burner start were counted in memory 6, are using a division member 30 in Relation to the number of cases in which a detonation attempt until successful burner start was needed, counted in memory 5, set.
  • the two quotients are getting smaller as the number The burner starts, in which only one ignition attempt is necessary increases, while the Number of burner starts, where two or three ignition attempts are necessary, constant stay. If two or three ignition attempts are needed, the corresponding one increases Quotient.
  • the respective minima of the quotients are stored together with time information from an operating hours counter 31 in the memory 8. If more than one ignition attempt is required at a burner start, the processor 28 calculates a gradient with the aid of a gradient sensor 32 from the respective minimum of the quotients, the number of operating hours when the corresponding minimum is reached, the corresponding quotient for two or three necessary ignition attempts and the number of operating hours , If the gradient exceeds a value G u predetermined in the memory 8, and at the same time drops below a different predetermined value G o (G o > G u applies), then this is an indication that the burner has to be maintained due to contamination. The processor 28 outputs a corresponding signal to the display 10. If the limit G o is exceeded, this is an indication of an error in the ignition or gas supply; the processor gives a corresponding signal to the display 10, indicating that the ignition and gas supply must be checked for faults.
  • FIG 3 shows the algorithm of the method from the first ignition attempt to the successful one Operation or a lockout.
  • FIG. 4 A variant of this method is shown in FIG. 4.
  • the processor 28 operates in the stored program memory 8 and controls u.a. the igniter 2 and this the ignition electrode 21 of the burner 3. Will within a certain time after the ignition command does not detect sufficient flame formation, i. the first ignition attempt was unsuccessful, so the counter 5 is incremented.
  • the counter 5 shows the number of cases in which already the first attempt at ignition unsuccessful was. In an optimal operation, the counters remain 5, 6 and 7, which the number of indicate unsuccessful ignition attempts, to the value zero.
  • FIG. 5 shows the algorithm of the method illustrated in FIG. 4 from the first ignition attempt until successful operation or a lockout.
