In reference to automatic boiler controls, the max signal selector selects the higher of which two signals?

• A. Gas pressure and steam pressure
• B. Water temperature and steam pressure
• C. Airflow and steam pressure
• D. Steam pressure and signal controller

Answer: (C)

The correct answer identifies that the max signal selector is concerned with selecting the higher of two specific signals, which are airflow and steam pressure. This selection process is critical in the context of boiler operation as it ensures optimal performance. When the boiler system operates, maintaining proper airflow and steam pressure is essential for efficiency and safety. The max signal selector evaluates both the airflow into the boiler and the steam pressure being generated. By selecting the higher of these two signals, the system can adjust to ensure adequate combustion and steam generation, creating a balance that prevents issues such as inefficient combustion or overheating. In contrast, examining the other options provides clarity on why they do not fit the definition of the max signal selector. The other pairs like gas pressure and steam pressure, or water temperature and steam pressure, do not focus on the same critical aspects of airflow versus steam pressure management that influence a boiler's operational capacity. This highlights the key function of the max signal selector in adapting to the most immediate and impactful variable affecting the boiler's performance.
