Definitions

  • the invention is based on a control method a heater according to the type of the main claim, and from a heater to perform the procedure.
  • Heat exchangers are known from EP 0 184 612 B2 provided with a special protective layer and thus against the acid generator contained in the condensate of the exhaust gases are stable.
  • chimneys as exhaust gas routing offers the possibility of glazing fireclay inner tubes, flexible or rigid stainless steel tubes or too Insert plastic pipes so the chimneys are insensitive to exhaust gas condensate.
  • the control method according to the invention with the features of Claim 1 has the advantage that if necessary intended increase in burner output Condensate formation in the exhaust system with minimal Use of energy is prevented.
  • the dependence of the burner output setpoints on the by a temperature sensor arranged in the exhaust gas path recorded exhaust gas temperatures and from the exhaust gas routing is in advantageously by in a control unit stored characteristic curve determined. This ensures that during operation of the heater at any exhaust gas temperature a necessary according to the avoidance of condensate Burner output setpoint as the lower limit of the Burner capacity control range can be assigned.
  • the characteristic curve is represented by a pre-selectable potentiometer connected to the control unit is.
  • the burner output is the same as the one selected Characteristic curve determined burner output setpoints corrected. Because these burner output setpoints are larger as the originally set burner output, the corrected burner output in an advantageous manner a shorter on-time and / or longer off-time balanced the burner. This ensures that Heater does not deliver more heating energy than corresponding the heat requirement is necessary.
  • FIG. 1 shows the schematically shown Heater according to the invention for performing the control method according to the invention and FIG. 2 Characteristic field in a burner output / flue gas temperature diagram.
  • the heater shown schematically in Fig. 1
  • the heater has a burner 10.
  • One in one Heating water circuit with a flow 12 and a return 14 arranged heat exchanger 16 is called hot Combustion gases acted on by the burner 10.
  • the heating water circuit can be used by consumers e.g. in form of Heating system with space heaters, which in the form of radiant heat transfers the heating energy to the Give environment, or systems for Industrial water supply, for example with the Heating system can be combined.
  • An exhaust gas duct 18 is located above the heat exchanger 16 arranged, which are the exhaust gases generated during combustion dissipates to the outside environment. Via a coaxial to Exhaust gas duct 18 arranged line 20 can in the case of the burner 10 Combustion air can be supplied. Depending on the The amount of heat demand becomes the output of the burner 10 preferably continuously regulated between 60% and 100%.
  • Control procedure is the minimum necessary exhaust gas temperature determined to the exhaust gas temperature in the course of the exhaust system 18 to hold above the dew point. This was done in Laboratory tests the minimum necessary exhaust gas temperature immediately at the entry of the exhaust gases into the exhaust gas guide 18 determines that no condensate in the entire exhaust system 18th originated.
  • the minimum necessary exhaust gas temperature depends on this essentially of the length and diameter of the Exhaust duct 18 and the heat transfer between Exhaust duct 18 and the coaxially arranged line 20th for the supply of combustion air. A long Exhaust duct 18 requires a higher minimum necessary Exhaust gas temperature as a short exhaust gas duct 18.
  • Control procedure is carried out with the help of an above Heat exchanger 16, at the entrance of the exhaust gas duct 18 arranged temperature sensor 24, the exhaust gas temperature determined and in one with the temperature sensor 24th connected control unit 22 evaluated. Is the value of the measured exhaust gas temperature below the minimum necessary Exhaust gas temperature, so the according to Burner output set to heat demand increased. A The burner output is corrected until the the minimum necessary exhaust gas temperature has been reached.
  • burner output setpoints as the lower limit for the burner output control range Are defined. For example, with one measured exhaust gas temperature of 60 ° C a larger Burner output setpoint necessary to a minimum necessary exhaust gas temperature of, for example, 120 ° C reach than at a currently measured exhaust gas temperature of 90 ° C.
  • the Temperature sensor 24 detected exhaust gas temperatures with the compared the minimum necessary exhaust gas temperature. Is that measured exhaust gas temperature below the minimum necessary Exhaust gas temperature, it is according to the Set burner output actual value by means of heat request the burner output setpoint at the corresponding one Exhaust temperature replaced. This ensures that the Exhaust gas temperature not below the dew point during heating of the exhaust gas falls and the exhaust duct 18 is free of Exhaust condensate remains.
  • the assignment of the burner output setpoints to the Exhaust gas temperatures is a characteristic curve in the control unit 22 filed.
  • the characteristic curve is as shown in FIG. 2, decreasing with increasing exhaust gas temperatures, i.e. there are with increasing burner temperature lower burner output setpoints as the lower limit of the burner output control range possible.
  • the control method according to the invention activated.
  • Corresponding one by the control unit 22 in cooperation with a Outside temperature sensor determined setpoint for the The heater starts the flow temperature of the heating water Heat the heating water up to the setpoint.
  • the Heat demand is the heating output or the Burner output set between 60% and 100%. Is that measured exhaust gas temperature below the minimum necessary Exhaust gas temperature, the actual burner output value is determined by the burner output setpoint according to the characteristic in Control unit 22 corrected or raised.
  • these parameters are dependent different burner output setpoints as lower Limit for the burner output control range for one condensate-free exhaust gas routing 18 necessary. That is why for different minimum necessary exhaust gas temperatures different characteristics stored in the control unit 22, the are shown in dashed lines in Fig. 2.
  • Exhaust gas guide 18 can be a function of exhaust gas guide 18 selected between the characteristics shown in FIG. 2 become.
  • Characteristic 1 is the lower adjustable characteristic in heating systems with a short exhaust system 18 and one low value for the heat transfer between the Exhaust duct 18 and line 20 for the supply of Combustion air selected, while curve 5 as the upper adjustable characteristic with a long exhaust system 18 and a high value for the heat transfer between the Exhaust duct 18 and line 20 for the supply of Combustion air is selected. Between these two Characteristic curves are corresponding fine-tuning with regard to Length of the exhaust duct 18 and the heat transfer through the Characteristic curves 2,3 and 4 possible.
  • the setting of those necessary for exhaust gas routing Characteristic curve is made by a potentiometer 26.
  • This is connected to the control unit potentiometer 26 so Heater attached that the operator or the Installer of the heating system without any disassembly of the Heater can make the appropriate setting.
  • the heating energy supply may be greater than that originally required according to the heat requirement.
  • the higher burner output delivered correct that the heating energy supply actually corresponds to the required amount of heat will be shorter Switch-on phases and / or longer switch-off phases of the Burner 10 set by the control unit 22.
  • the Switching hysteresis in a two-point control can be how already in DE 39 07 955A described, optimized.
  • the exhaust duct 18 determines, i.e. the temperature sensor 24 is arranged inside the heater. of course is it is also possible to use a temperature sensor 24 ' the exhaust gas temperature at the end of the exhaust gas duct 18 determine. This makes the determination of the minimal necessary exhaust gas temperature regardless of the length of the Exhaust gas routing 18. Bring the temperature sensor 24 'to Measurement of the wall temperature at the end of the inner wall of the Exhaust gas guide 18, so will be different Thermal transitions also taken into account. Both points taken together, i.e.
  • the application of the standard procedure is not restricted on a heater according to the embodiment, but can be used wherever with one conventional control method to an exhaust gas duct connected heater is operated.
