Problems solved by technology

However, what may appear to be an obvious advantage immediately becomes a disadvantage because the conversion rate becomes large very quickly due to the non-linearity, making it overcompensated
Starting from a threshold, even small changes can cause strong changes in the response factor of more than 30%
Since strict limits are set for the response factor in t

Example Embodiment

[0029] figure 1 The FID 1 is shown in FIG. 1 with a combustion chamber 2 in which an electrode device 3 is arranged to measure the current from the gas flame 4 to the electrode 5 of the electrode device 3. Here, the current measuring device 6 includes an amplifier not shown further, so that the generally very small current from the gas flame 4 can be measured.

[0030] A burner nozzle 7 with a nozzle 8 on the output side projects out of the combustion chamber 2 to eject a gas mixture 9 to be ignited between the electrode devices 3. The gas mixture 9 is formed on the input side of the burner nozzle 7 by mixing the oxygen-containing combustion gas 10 and the carbon-containing measurement gas 11 and transporting them to the nozzle 8 through the transmission channel 12.

[0031] Additionally, outside the burner nozzle, oxygen-containing combustion air 13 is introduced into the combustion chamber 2. This leads to reaction with the combustion gas 10, thereby forming water (H 2 O) and ca...

Abstract

The invention relates to a flame ionization detector. The flame ionization detector has a combustion chamber with an electrode arrangement for measuring an electric current from a gas flame to an electrode of the electrode arrangement, a burner nozzle having at least one output-side outlet for ejecting a gas mixture to be ignited between the electrode arrangement and having at least one input-side inlet for feeding a hydrogen-containing combustible gas and a carbon-containing gaseous analyte through a transport channel to the outlet, and a feeder for feeding oxygen-containing combustion air into the combustion chamber, wherein at least one cut-out is provided in the burner nozzle, through which cut-out combustion air can pass from the combustion chamber into the gas mixture flowing out of the outlet. The invention also comprises a corresponding vehicle, a power station, and a corresponding burner nozzle.

Description

technical field [0001] The invention relates to a flame ionization detector comprising: a combustion chamber having an electrode arrangement for measuring the ion current from a gas flame to an electrode of the electrode arrangement; a burner nozzle having an output side at least one nozzle and at least one inlet on the inlet side for spraying the gas mixture to be ignited between the electrode arrangements, the at least one inlet for injecting hydrogen-containing combustion gas and carbon-containing measuring gas conveyed to the nozzle through a transfer channel; and means for conveying oxygen-containing combustion gases into the combustion chamber. Furthermore, the invention relates to an internal combustion engine as well as a power station and corresponding burner nozzles. Background technique [0002] The field of application of the invention extends to process control, where organic compounds such as hydrocarbons in gases are measured and monitored, for example by bur...
