Monitoring flue gas composition is crucial for ensuring optimal combustion in a boiler system. The combustion process involves burning fuel to generate heat, and the efficiency of this process directly affects the performance of the boiler. By analyzing the flue gas, operators can determine the presence of combustion products such as carbon dioxide, oxygen, carbon monoxide, and nitrogen oxides.

An accurate assessment of these gases can indicate whether the fuel is being used efficiently. For instance, a high level of unburned hydrocarbons or carbon monoxide may suggest incomplete combustion, which can result in wasted fuel and increased emissions. On the other hand, an adequate amount of oxygen in the flue gas indicates that combustion is occurring effectively.

By maintaining the right fuel-to-air ratio and optimizing combustion conditions, operators can improve fuel efficiency, reduce emissions, and ensure the boiler operates safely and effectively. This not only optimizes performance but also reduces the risk of hazardous situations that can arise from poor combustion.
