What impact does scaling have on boiler operation?

• A. Improves heat transfer efficiency
• B. Decreases heat transfer efficiency
• C. Increases the overall lifespan of the boiler
• D. Has no impact at all

Answer: (B)

Scaling in a boiler refers to the buildup of mineral deposits on the heat transfer surfaces, which can significantly hinder the efficient operation of the boiler. When scaling occurs, it forms an insulating layer that separates the water from the heat exchange surfaces. This insulation effect reduces the amount of heat that can be transferred from the heat source to the water, resulting in decreased thermal efficiency. As a consequence, the boiler must work harder to achieve the desired temperature and pressure, leading to increased fuel consumption and operating costs. Moreover, the presence of scale can create hotspots on the heating surfaces, which may cause localized overheating and potential damage, further affecting the boiler's efficiency and safety. In contrast, clean surfaces promote optimal heat transfer capability, which is essential for efficient boiler operation. Therefore, the impact of scaling is detrimental as it results in a decrease in heat transfer efficiency.
