Which system monitors the combustion efficiency in a boiler?

The flue gas analyzer is the system specifically designed to monitor combustion efficiency in a boiler. It analyzes the composition of the gases emitted from the boiler, measuring parameters such as oxygen, carbon dioxide, carbon monoxide, and others. By evaluating the levels of these gases, the analyzer provides critical information about how complete the combustion process is, indicating whether the fuel is being burned efficiently and whether the boiler is operating within optimal parameters.

Monitoring combustion efficiency is essential for maintaining boiler performance and ensuring that it operates safely and economically. Efficient combustion minimizes fuel consumption and reduces emissions, which is crucial not only for cost savings but also for environmental compliance.

Other systems like the safety interlock system, stack temperature gauge, and water gauge serve different functions. The safety interlock system ensures safe operation by preventing hazardous conditions, the stack temperature gauge measures the temperature of the flue gases to monitor system performance, and the water gauge indicates the level of water in the boiler. However, none of these tools directly assesses how efficiently combustion is occurring, which is the unique role of the flue gas analyzer.
