What is the primary reason for keeping a daily log of flue gas temperature?

  1. It provides valuable information in case of an explosion

  2. It is required by the superintendent

  3. To detect changes in operation that cause heat loss

  4. It helps in maintenance scheduling

The correct answer is: To detect changes in operation that cause heat loss

Keeping a daily log of flue gas temperature is crucial because it enables operators to detect changes in the operation of the boiler that may result in heat loss. Monitoring flue gas temperatures helps in identifying inefficiencies in the combustion process, such as incomplete combustion, which can lead to wasted fuel and increased operational costs. By regularly tracking these temperatures, operators can observe trends over time, allowing them to implement corrective measures when temperatures deviate from expected values. This proactive approach not only improves efficiency but also enhances safety and prolongs equipment life by ensuring optimal performance. While reporting to the superintendent and aiding in maintenance scheduling are important, they are secondary benefits rather than the primary reason for logging flue gas temperature. Additionally, while having this log may provide information in the event of an explosion, the core function is centered on operational efficiency and heat loss detection.
