To determine the correct temperature at which the superheater outlet header is operating based on the required thickness of 54.35 mm, it's essential to consider the relationship between pressure, temperature, and material strength in pressure vessels.

The thickness required for a superheater component is often calculated using formulas that include factors like the internal pressure, material properties, and the operational temperature. Typically, as the operating temperature of a superheater increases, the material must be able to withstand higher thermal stresses and pressures, which directly influences the thickness required.

In many cases, the thickness increases with temperature due to the need for added strength to cope with the increased thermal expansion and stress. For common materials used in power engineering, such as carbon steel or alloys, there are established guidelines and formulas that dictate the required thickness at various operating temperatures.

Considering the thickness provided, 54.35 mm is indicative of a temperature operating in the higher range often seen in superheater applications, such as in the vicinity of 500°C. At this temperature, the materials used would exhibit specific yield strengths, and the associated stress calculations would lead to a requirement of approximately that thickness for safety and function.

Thus, the choice of 500°C aligns with the expected thickness required for a superheater outlet
