Definitions

  • the present disclosure relates to the estimation of fuels in a combustion device.
  • the present disclosure relates to the estimation of fuels in the form of combustible gases or gas mixtures containing hydrogen.
  • Common gas types used in combustion devices include those from the E-gas group (according to EN 437:2009-09) and gases from the B/P-gas group (according to EN 437:2009-09). Like almost all gases from the second gas family (according to EN 437:2009-09), gases from the E-gas group contain methane as their main component. Like all gases from the third gas family (according to EN 437:2009-09), gases from the B/P-gas group are based on propane gas. Mixtures based on methane or propane ultimately represent mixtures of different gas sources that can be used to supply the combustion device. The mixing and combustion of natural gas and hydrogen is becoming increasingly interesting.
  • the measured ionization current changes with increasing hydrogen content if the excess air is kept constant. If the air supply or fan speed or power is controlled to a constant ionization current setpoint for a constant air volume, the air ratio ⁇ changes with a change in the hydrogen content. This also results in a change in the efficiency of the combustion device. Increased levels of undesirable combustion products such as carbon monoxide may also occur.
  • an ionization current setpoint is stored for methane gases depending on the air supply, fan speed, or power. Hydrogen admixtures result in different ionization currents than, for example, pure methane gas. However, due to the small amounts of hydrogen admixtures known to date, only minor deviations in the air ratio ⁇ and thus in the efficiency were observed.

  • the speed of a fan of a combustion device is determined.
  • the determined speed is compared with a reference value.

  • the aim of the method is DE10030630A1 is a practical trade-off between the greatest possible accuracy in the stationary state of the fan on the one hand and errors due to dynamic changes on the other.
