When installing a steam boiler, what is required for safety?

The requirement for installing a steam boiler includes both a water-gauge glass and a pressure gauge to ensure safety during operation. The water-gauge glass allows operators to visually monitor the water level inside the boiler. This is crucial because maintaining the appropriate water level is necessary to prevent the boiler from running dry, which could lead to overheating and potentially catastrophic failure.

The pressure gauge, on the other hand, is essential for indicating the internal pressure of the steam in the boiler. Operating a steam boiler at the correct pressure is critical for safe and efficient operation. Knowing the pressure helps prevent over-pressurization, which could also cause dangerous situations, such as explosions or damage to the boiler system.

Combining both of these gauges provides a comprehensive safety measure, as one monitors water level while the other tracks pressure. This dual monitoring helps maintain optimal operational conditions and safeguards against potential hazards that could arise from improper handling of the steam boiler.
