Final answer:
Flue gas analyses often target components like carbon dioxide, sulfur dioxide, nitrous oxide, carbon monoxide, nitrogen oxides, sulfur oxides, and particulate matter to monitor and control emissions and ensure good air quality. The option (B) is correct.
Step-by-step explanation:
Three types of flue gas analyses are:
- Carbon dioxide (CO₂), Sulfur dioxide (SO₂), Nitrous oxide (N₂O)
- Carbon monoxide (CO), Nitrogen oxides (NOx), Sulfur oxides (SOx)
- Particulate matter (smoke, dust)
These analyses are crucial for monitoring and controlling emissions from combustion processes, ensuring environmental compliance and air quality. For example, sulfur dioxide and nitrogen oxides can lead to the formation of acid rain, while carbon monoxide can affect air quality and human health. Particulate matter analysis helps measure the level of particles that may cause respiratory issues. The use of correct analytical techniques is essential in providing information about the efficiency of combustion and the need for pollution-control measures. Therefore, option (B) is correct.
