New York Low Pressure Boiler COF Practice

What is the purpose of a gauge glass on a boiler?

1. To measure pressure

2. To monitor water level

3. To display temperature

4. To calibrate safety valves

The correct answer is: To monitor water level

The primary purpose of a gauge glass on a boiler is to monitor the water level within the boiler. A gauge glass provides a clear visual representation of the water level, allowing operators to easily see whether the water is at a safe operating level. Maintaining the appropriate water level is crucial for the safe and efficient operation of a boiler; insufficient water can lead to overheating and damage, while too much water can cause operational issues and reduce efficiency. In the context of boiler operation, the gauge glass serves as an essential tool for operators to ensure that the water level is within specified limits, thus preventing potential hazards associated with low or excessive water levels. Understanding the role of the gauge glass helps operators maintain boiler safety and efficiency, making it a vital component in boiler operation.
