Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Consider the balance of CO and CO₂ to evaluate effectiveness.
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.
💡 Hint: Remember to compare the actual O₂ to the stoichiometric requirements!
