Definitions

  • the invention is based on a device for operation a heating system of the independent type Claim.
  • a heating system of the independent type Claim When operating heaters moisture-sensitive fireplaces, make sure that the Dew point temperature of the water vapor during combustion resulting exhaust gases is not permanently undercut to prevent sooting of the exhaust system.
  • the device according to the invention for operating a Heating system contains a burner whose exhaust gas is above a chimney is removed. It is characterized by that a chimney draft sensor is provided, which the pressure of the Exhaust gas detected and its output signal one Signal processing to recognize a Exhaust gas in the chimney is below the dew point. Measurements have shown that the pressure curve of the exhaust gas in the Chimney Information about a possible drop below the dew point gives. The quality of the dew point detection can be determined by the Improve acquisition of another parameter. At a impending dew point can quickly Countermeasures that target a targeted increase Exhaust gas temperature or a lowering of the water vapor dew point cause the exhaust gas to be initiated. Therefore allowed this sensor system replaces an old heat generator with relatively high exhaust gas temperatures due to a modern Heat generator with lower exhaust gas temperatures.
  • the first limit value depends on the temperature of the exhaust gas. This will find the two Temperature and exhaust pressure parameters alike Consideration in a dew point monitoring. The quality dew point detection improves.
  • the first depends on appropriate further training Limit from the fireplace's specifications. This allows the Dew point monitoring individually to the special Adjust the conditions of the fireplace. So that will Interactions between the special structure of the fireplace, resulting pressure curve of the exhaust gas and Below the dew point.
  • Chimney draft sensor and / or temperature sensor at the chimney entrance are arranged.
  • Limit values based on comparative measurements for the different chimney classes give at the chimney entrance recorded variables temperature and pressure also information about whether the dew point is at a critical point based on experience how to go below the mouth of the fireplace.
  • the Positioning the sensors at the chimney entrance reduces the necessary wiring effort.
  • the assembly of the sensors is easy to do.
  • FIG. 1 shows it possible embodiment of a schematic heating system shown and in the following Description explained in more detail.
  • Figure 2 is a block diagram a further embodiment.
  • the heater shown schematically in Figure 1 has a burner 10.
  • a burner 10 One in a heating water circuit with a flow 12 and a return 14 arranged Heat exchanger 16 is filled with hot combustion gases Burner 10 acted upon. These are over a fireplace 18th dissipated.
  • a chimney draft sensor detects the pressure of the exhaust gas 24, the output signal of a signal processing 22 is fed. It controls the burner 10.
  • the Signal processing 22 in addition to the output signal of the Chimney draft sensor 24 also that of a temperature sensor 26 fed.
  • the burner 10 is dependent on these controlled both signals.
  • the chimney draft sensor 24 is preferably at the exhaust gas inlet in arranged the fireplace 18. There he records the pressure curve of the Exhaust gas. As a rule, there will be a vacuum set that is higher than the necessary delivery pressure for the heat generator. As chimney draft sensors 24 can in principle the well-known pressure gauges for Get involved. For special use for Dew point detection, however, requires that their Resolution is in the range of approx. 0.1 Pa. In this regard The signal processing 22 evaluates pressure changes. As Chimney draft sensor 24 becomes, for example, a force-spring system used, the two chambers separated by a membrane. The Movement of the membrane serves as a measure of the pressure.
  • Electric pressure gauges offer the advantage of being pressure proportional electrical sizes slightly different from that Signal processing 22 can be evaluated. Therefor are basically capacitive, inductive or Piezoelectric measurement methods are available.
  • Temperature sensors 26 are well known to be used come, for example, thermocouple or NTC sensor.
  • the output signal of the temperature sensor 26 is also the Signal processing 22 supplied.
  • the signal processing 22 can be used to regulate the Brenners 10 are used, the one Prevents falling below the dew point. If the one Corresponding limit value below the dew point reached, the signal processor 22 controls the burner 10 so that the exhaust gas temperature increases. At conventional heaters with load-dependent Exhaust gas temperature comes a sensor-controlled limitation of minimal partial load. The limit is so too choose to prevent falling below the dew point Control of the burner 10 is timely that the System inertia is already taken into account. The limit can also depend on the gradient of the pressure curve.
  • the proposed sensor system for dew point monitoring is used especially when for example when replacing a burner system Maintaining the exhaust gas discharge the exhaust gas temperature reduced and thus the risk of sooting the fireplace 18 increases rapidly. Monitoring is carried out in the Burner control integrated. The limits are at Commissioning to adapt to the specific chimney specifications and to inform the signal processor 22.
