  • the heating device has a positive temperature coefficient. Due to the design of the heater with a positive temperature coefficient, ie as a PTC thermistor, the heater can be used in a simple manner as a temperature sensor, since the resistance of the heater so also increases with increasing temperature. The use of the heating device as a level sensor works essentially on the same principle, since the temperature of the heater in areas where no water to be evaporated is present, can increase by a small amount.

These strips can then preferably also be arranged substantially parallel to the course of filling levels, so that a sinking or rising level when descending or rising successively passes the individual strips. With appropriate design of the container then the heating power generated by the individual strips, depending on whether the strips are at the current level below or above a level line, better or less well transferred to the water.

  • the state of the steamer which is determined by means of the aforementioned method, in particular relates to the degree of calcification of the evaporator. This can be determined, for example, by monitoring the efficiency of the heater.
  • This efficiency results from the temperature of the heater, the change in the temperature of the heater, the temperature of the water and from the change in the temperature of the water to be evaporated. If the time span until reaching a certain temperature of the water at a substantially constant temperature of the heating device is comparatively long, then this is a substantially unambiguous indication of the advanced calcification of the steam generator, since a lime layer is a comparatively good heat insulator. Then full water level comparison measurements are needed to assess how the time to reach a given temperature changes. A signal requesting descaling may be issued to an operator. Alternatively or additionally, an anti-adhesion coating may prevent or reduce the setting of lime.

In this way, therefore, the production of the thick-film heating device according to the invention is simplified and guarantees a comparatively high quality standard.
  • a method for cooling a heating device of a steam generator can also solve the problem underlying the invention.
  • the heating device is cooled in a region by steam conducted past the heating device, in particular if the water to be evaporated has evaporated to such an extent that its surface is below an upper edge of the heating device.

This possibility represents a safeguard for the thick-film heater 130, as this can prevent overheating and thus destruction of the thick film heater 130.
  • the temperature of the thick-film heater 130 can be kept the same during the evaporation process, as long as the level of the annular region 124 is above the residual level 144. This effect can be explained by the fact that the vapor rising on the surface of the pipe section 114 along the steam guide section cools this pipe section 114, whereby the thick film heater 130 is also cooled. However, if the level drops below the residual level 144 indicated by the wavy line, sufficient steam is no longer generated to sufficiently cool the thick film heater. Accordingly, their temperature increases, which also increases the resistance of the thick film heater 130 when using a PTC thermistor as a heater, which can be detected.

This may be due to the fact that the heater 328, in the present case the thick film heater 330, is defective. However, it can also be an indication that the transfer of the heating power of the thick-film heater 330 in the water to be evaporated does not take place to the desired extent.
