What is the purpose of monitoring flue gas composition?

Monitoring flue gas composition is crucial primarily for optimizing combustion efficiency. By analyzing the gases emitted from combustion processes, operators can assess how effectively fuel is being burned. The composition of flue gas typically includes oxygen, carbon dioxide, carbon monoxide, nitrogen oxides, and unburned hydrocarbons.

When the combustion process is optimized, it means that the right amount of fuel is being used in conjunction with the appropriate amount of air. If the oxygen levels are too high, it indicates that there is excess air, which could result in energy wastage. Conversely, if oxygen levels are too low, this may signify incomplete combustion, potentially leading to higher emissions of harmful pollutants like carbon monoxide and particulates, as well as lower efficiency in energy production.

In summary, monitoring flue gas composition aids in tweaking the combustion process to achieve a better fuel-to-air ratio, ensuring that the system operates efficiently, minimizes waste, and adheres to environmental regulations. This efficiency not only saves fuel costs but also reduces the environmental impact of emissions.
