Final answer:
Carbon dioxide is now being measured in flue gases because of its effect on the atmosphere, to indicate incomplete combustion, and to accurately tune carbon dioxide absorbers.
Step-by-step explanation:
Carbon dioxide is now being measured in flue gases for several reasons. One of the main reasons is because of its effect on the atmosphere. Carbon dioxide is a greenhouse gas that traps heat from the sun, contributing to global warming. By measuring carbon dioxide in flue gases, we can monitor and control the amount of this gas being released into the atmosphere.
Another reason carbon dioxide is measured in flue gases is because it indicates incomplete combustion. Incomplete combustion occurs when there is not enough oxygen present during the burning of fossil fuels, leading to the production of carbon monoxide and carbon dioxide. By measuring carbon dioxide levels, we can assess the efficiency of the combustion process and make adjustments if necessary.
Measuring carbon dioxide in flue gases is also important for accurately tuning the carbon dioxide absorbers. Carbon dioxide absorbers are devices used to capture and store carbon dioxide, preventing it from being released into the atmosphere. By accurately measuring carbon dioxide levels, we can optimize the performance of these absorbers to effectively reduce carbon dioxide emissions.
