Definitions

  • Fluctuations in the air ratio ⁇ occur due to changes in air temperature and / or air pressure. Combustion devices are therefore set with an excess of air. This measure serves to avoid unsanitary combustion. A disadvantage of the adjustment of combustion devices to an excess of air is a reduced efficiency of the system.
  • Speed sensors and air pressure switches can also be used to measure the air throughput.
  • a disadvantage of speed sensors is that they are not sensitive to fluctuations in air temperature and air pressure.
  • a disadvantage of air pressure switches is that air pressure monitoring is only possible at a certain pressure. After all, by using several switches, air pressure can be monitored at several pressures. However, readjustment in the entire operating range of the combustion device has hitherto hardly been possible. A solution for adjustment at one point has also previously required two units.
