• A. Steam chamber
• B. Water column

• D. Boiler room

Answer: (B)

The high low water alarm of a steam boiler is typically located in the water column because the water column serves as a vital component that connects the boiler to the gauge glass. It provides a clear view of the water level within the boiler and allows for accurate measurement of the water level. By placing the high low water alarm in the water column, the system can effectively monitor the water levels and alert operators if they fall below the safe operating levels or rise too high, which could indicate a potentially dangerous situation. Monitoring the water level is crucial for the safe and efficient operation of the steam boiler, and the water column is specifically designed for this purpose, making it the correct location for these alarms.
