What is "scaling," and how does it affect boiler performance?

Scaling refers to the buildup of minerals, such as calcium and magnesium, on the surfaces of the boiler and its components, particularly in areas where water is heated. When water is heated, it can precipitate these minerals, forming solid deposits that adhere to the surfaces inside the boiler. This buildup acts as an insulator, significantly reducing the efficiency of heat transfer from the boiler's heating surfaces to the water or steam being produced.

As a result, more energy is required to achieve the desired temperature, leading to higher fuel consumption and increased operational costs. In severe cases, scaling can lead to overheating, reduced boiler life, and the risk of failure due to inadequate heat exchange. Addressing scaling is crucial for maintaining optimal boiler performance, ensuring efficient operation, and prolonging the equipment's lifespan.
