During boiler operations, what is the main consequence of inadequate lubrication?

Inadequate lubrication during boiler operations primarily results in the overheating of components. Lubrication is essential in reducing friction between moving parts, such as pumps, bearings, and valves. When lubrication is insufficient, these components experience increased friction, which generates excess heat. This overheating can lead to component failure, reduced operational reliability, and increased maintenance demands, thereby ultimately compromising the entire system's performance.

Overheating can also affect the structural integrity of components and lead to catastrophic failures if not managed promptly. While inadequate lubrication can also indirectly contribute to fuel consumption and efficiency losses, the immediate and direct consequence is the thermal strain on parts that are meant to operate smoothly. This is why understanding the importance of proper lubrication in maintaining boiler operations is critical for any machinist’s mate.
