Which type of damage can prolonged overheating cause to boiler components?

Prolonged overheating of boiler components can lead to metal fatigue and deformation as these materials are designed to withstand certain temperature ranges and stresses. When the operating temperature exceeds the material's capacity, it can cause the metal to lose its structural integrity. This phenomenon occurs as the repeated thermal cycling weakens the metal structure, leading to cracks, warping, or other forms of deformation. This is particularly critical in high-stress areas of the boiler where strength and shape maintenance are essential for safe operation.

Understanding the implications of overheating on metal components highlights the importance of monitoring and maintaining optimum operational conditions in boiler systems. Regular inspections can help detect early signs of fatigue, allowing for preventive measures before catastrophic failures occur.
