What will be the effect on operating steam plant if the airflow transmitter fails?

• A. Fuel oil header pressure will stabilize
• B. Fuel oil header pressure will decrease to minimum
• C. Fuel oil header pressure will increase
• D. Steam flow will decrease

Answer: (B)

When an airflow transmitter fails in a steam plant, it directly impacts the ability to monitor and control the combustion process. The transmitter plays a critical role in measuring the airflow necessary for optimal fuel combustion. If it fails, the system may not receive accurate airflow data, which can lead to an improper air-to-fuel ratio. In this case, a failure of the airflow transmitter often results in a decrease in fuel oil header pressure. This happens because the combustion controls may react to the lack of accurate airflow data by reducing fuel oil flow to maintain safe operating conditions, which can lead to a decrease in pressure within the fuel oil system. As a consequence, the decrease in fuel oil pressure could eventually lead to inadequate burning of fuel, impacting overall plant efficiency and potentially resulting in unsafe conditions or boiler shutdown. Understanding this relationship is essential for maintaining efficient and safe operations within a steam plant.
