Upper HP reference · 460 °C

50 mm insulation: heat loss and outside surface

Upper HP support flange with metal bellows. Oman reference weather, measured component geometry, outdoor convection and radiation.

Calculated result

Bare heat loss	47.174 kW
Physics-model residual	1.167 kW
Public planning residual	1.887 kW · 96% cap
Heat retained shown publicly	45.287 kW
Outside surface	53.1 °C · review thickness

Calculation inputs: 460 °C process, 27.7 °C ambient, 3.1 m/s wind, 50 mm Wired Mat, measured support-flange and corrugated-bellows geometry. The thickness graph uses the physics-model residual; the public savings total keeps the 96% reduction cap.

What the result means

For the Upper HP support flange with metal bellows and the stated Oman weather inputs, the model gives 53.1 °C outside surface and does not meet the ≤45 °C target.

Residual heat loss and outside-surface temperature fall. The improvement becomes smaller at each additional thickness step, so clearance, mass and access still need engineering review.

Is 50 mm enough at 460 °C?

For the Upper HP support flange with metal bellows and the stated Oman weather inputs, the model gives 53.1 °C outside surface and does not meet the ≤45 °C target.

What changes when thickness increases?

Residual heat loss and outside-surface temperature fall. The improvement becomes smaller at each additional thickness step, so clearance, mass and access still need engineering review.

Are these thermography measurements?

No. These values are calculated from the measured geometry and operating inputs. The separate survey thermogram is evidence of the exposed hot component, not the insulated prediction.
