Thermal conductivity measurement is used for the determination of________________?
Correct answer: D. CO2 percentage in the flue gas
- A. O2 percentage in the flue gas
- B. Specific gravity of petrofuels
- C. Composition of an alloy
- D. CO2 percentage in the flue gas
Explanation
Carbon dioxide has a thermal conductivity sufficiently different from the major gases in flue gas for a thermal-conductivity analyser to estimate its percentage. Oxygen is more commonly measured by a paramagnetic or zirconia analyser.
