What critical strategy should be adopted when changing boiler operating temperatures?

Gradual temperature adjustments are vital when changing boiler operating temperatures because they help prevent thermal shock and avoid stress on the boiler system. Sudden or immediate changes can lead to structural damage, as the rapid expansion or contraction of materials can create cracks or other forms of failure. This careful approach allows the boiler components to adjust steadily to the new conditions, ensuring that the system operates safely and efficiently.

By monitoring temperature gauges, personnel can make more informed adjustments and recognize any fluctuations that may indicate problems. The practice of ignoring gauges would pose serious risks, as it could lead to overheating or other operational failures. Additionally, using circuit breakers is irrelevant in the context of temperature adjustments, as they are not designed to control the temperature but rather to protect electrical systems from overloads.
