What is the primary purpose of a pressure gauge on a boiler?

The primary purpose of a pressure gauge on a boiler is to monitor the pressure in the steam space or water column. This is crucial for safe and efficient boiler operation. By providing a real-time reading of the pressure, it allows operators to ensure that the boiler is functioning within safe operational limits. Maintaining the correct pressure is essential for the effective transfer of heat and for preventing potential hazards such as excessive pressure buildup, which can lead to equipment failure or catastrophic accidents.

In a boiler system, pressure affects both the boiling point of water and the efficiency of steam generation. An accurate pressure gauge helps in diagnosing operational issues and in making necessary adjustments to maintain optimal performance, ensuring safety and reliability in the operation of the boiler.
