Question 1.
What gases are primarily measured in flue gas analysis?
Show hintHide hint
Think about the basic combustion products.
Question 2.
What device is used for measuring gas composition?
Show hintHide hint
Its name starts with 'O' and is used to analyze gas.
3Question 3.
What does the Orsat apparatus measure?
- Temperature
- Volume fractions of gases
- Pressure
Show hintHide hint
Think about what we use it for in combustion analysis.
4Question 4.
True or False: High levels of CO₂ always indicate efficient combustion.
- True
- False
Show hintHide hint
What do you remember about the balance between CO₂ and O₂?
Question 5.
A combustion system shows 15% CO₂, 0.5% CO, and 5% O₂ in its flue gases. Are these levels indicative of complete combustion? Justify your answer with appropriate reasoning.
Show hintHide hint
Consider the balance of CO and CO₂ to evaluate effectiveness.
Question 6.
If a system has an O₂ measurement of 3% with corresponding CO levels of 0.2%, calculate the excess air based on stoichiometric requirements of 3% O₂.
Show hintHide hint
Remember to compare the actual O₂ to the stoichiometric requirements!
