What is commonly monitored in a boiler to ensure efficiency?

Monitoring flue gas temperature in a boiler is crucial for ensuring its efficiency. The temperature of the flue gases, which are the exhaust gases emitted from the boiler, provides essential information about the combustion process and the overall efficiency of the system.

When flue gas temperature is too high, it may indicate that the boiler is not operating efficiently, as valuable heat is being lost through the exhaust. Conversely, if the temperature is too low, it could signify incomplete combustion, leading to unburned fuel and increased emissions of pollutants. Optimal flue gas temperature ensures that the boiler operates at peak efficiency, maximizing energy output while minimizing fuel consumption and environmental impact.

This monitoring is pivotal for maintaining safe operational levels, improving system performance, and adhering to regulatory requirements regarding emissions. By keeping a close eye on flue gas temperature, operators can adjust operations to maintain efficiency and maximize the lifespan of the boiler system.
