Improper heat transfer in a boiler can lead to overheating of heating surfaces. This occurs when the design or operational parameters of the boiler do not allow for effective absorption of heat by the water or steam, resulting in excessive temperatures that can cause damage. When heating surfaces overheat, there is a risk of metal fatigue, material failure, or even catastrophic failure of the boiler.

In addition, overheating can lead to issues like thermal stress, scaling, and corrosion, which further compromise the integrity and efficiency of the boiler. Maintaining appropriate heat transfer is crucial for ensuring safe operation and prolonging the lifespan of the boiler system.

In contrast, increased steam production, reduction in boiler pressure, and enhancement of energy efficiency would not typically be a direct result of improper heat transfer. In fact, these factors might be adversely affected or not realized at all in a scenario where heat transfer is not effective.
