Arkansas Boiler Operator Practice Exam

As boiler steam pressure increases, what else also increases?

1. Water level

2. Temperature

3. Sound level

4. Fuel consumption

The correct answer is: Temperature

As boiler steam pressure increases, the temperature of the steam also increases. This relationship is fundamental to the principles of thermodynamics applied in boilers, specifically according to the steam tables that categorize steam properties based on pressure and temperature. In a pressurized environment, as pressure rises, the boiling point of water increases, which leads to a corresponding increase in the steam’s temperature. Although other factors like water level, sound level, and fuel consumption may be influenced by operating conditions or changes in demand, they do not have the direct and predictable relationship with pressure that temperature does. The correlation between pressure and temperature is a key aspect of boiler operation, ensuring that operators can effectively control and monitor their systems for optimal performance.
