Monitoring the combustion process is crucial for maintaining optimal performance in a boiler system. When the combustion process is properly monitored, it helps to ensure that the fuel is burning efficiently and completely. This efficiency is directly linked to the reduction of pollutants emitted into the atmosphere. By closely observing parameters such as oxygen levels, temperature, and fuel-to-air ratios, operators can quickly identify and rectify situations that may lead to incomplete combustion, which contributes to excessive emissions of harmful gases like carbon monoxide, nitrogen oxides, and unburned hydrocarbons.

In addition to optimizing fuel use, effective monitoring can also help maintain compliance with environmental regulations designed to limit emissions and protect air quality. This makes it a critical aspect of boiler operation not only for regulatory compliance but also for the health of the surrounding environment.

The other choices, while they may be related to overall boiler efficiency and safe operation, do not directly address the immediate goals of monitoring combustion, which are primarily focused on controlling emissions and ensuring environmental accountability.
