15.7 CO
2
sensor for Carbon Dioxide measurement in combustion processes
Carbon Dioxide (CO
2
) is the result of combustion of an organic compound in presence of a quantity of oxygen
sufficient to complete its oxidation. In nature, it is also produced by aerobic bacteria during the process of alco-
holic fermentation and is the by product of respiration.
Many combustion processes are defined with 'mixed fuel' and is therefore difficult to calculate the amount of CO
2
produced. To avoid this drawback, the only way to know the amount of CO
2
produced in a combustion process
with 'mixed fuel' is to measure the CO
2
with special NDIR sensors.
15.7.1 Installing the CO
2
sensor
When the CO
2
(position S1 - S6) is mounted in the CHEMIST 600, it is mandatory to configure the autozero by
setting it at 60 seconds, in order to allow for a proper pre-heating of the sensor itself.
