Class 5 Boiler Practice Exam 2025 – The Comprehensive All-in-One Guide to Exam Success!

The purpose of a pressure gauge on a boiler is to display steam pressure. This measurement is crucial for several reasons. Firstly, steam pressure indicates the performance and efficiency of the boiler – it helps operators understand the operating conditions within the boiler system and determine if it is producing steam at the required pressure for its intended application.

Maintaining the correct steam pressure is vital for the safety and functionality of the boiler. Too high or too low steam pressure can lead to equipment damage, safety hazards, or inefficient operation. Thus, monitoring the steam pressure allows operators to make necessary adjustments to ensure the boiler operates within safe parameters.

In contrast, other aspects of boiler operation such as temperature measurement, water level indication, and fuel consumption monitoring are handled by different gauges or instruments that serve distinct purposes unrelated to the direct measurement of steam pressure.
