What does a gauge glass indicate in a boiler system?

A gauge glass in a boiler system is specifically designed to show the water level within the boiler. It typically consists of a vertical tube or a glass that is connected to the water space of the boiler, allowing the operator to visually confirm the level of water present. This is crucial for safe boiler operation because maintaining the appropriate water level is essential to prevent overheating and potential damage to the boiler. If the water level is too low, it may result in overheating of the boiler components, while too high a water level can lead to carryover of water into the steam system, affecting the quality of the steam produced.

Understanding the purpose of a gauge glass is fundamental for proper boiler management and safety protocols, as it directly relates to the efficiency and longevity of the boiler system.
