What could indicate that a boiler is reaching a dangerous pressure during operation?

• A. Excessive noise
• B. Steam leakage from joints
• C. Visible gauge fluctuations
• D. Presence of white smoke

Answer: (C)

When assessing the operational safety of a boiler, visible gauge fluctuations represent a crucial indicator of pressure instability. Fluctuations in the pressure gauge can signal that the boiler's pressure is either rising beyond its safe operating limits or experiencing sudden changes in pressure, which could potentially lead to dangerous conditions. This might happen due to various factors, such as rapid heating, malfunctioning safety valves, or issues with the feedwater supply. By monitoring the pressure gauge closely, operators can determine if the pressure approaches alarming levels, allowing them to take corrective actions before a situation becomes critical. Continuous or severe fluctuations might require immediate attention, including the possibility of shutting down the boiler or conducting maintenance checks to prevent any catastrophic failures. Other indicators, such as excessive noise or steam leakage, may provide secondary hints about issues in the system, while the presence of white smoke is often unrelated to pressure but more indicative of combustion problems. However, visible gauge fluctuations directly correlate with boiler pressure status and are thus a primary flag for unsafe operating conditions.
