Heat-loss reduction planning cap, with retained heat shown in kW or MW.
HRSG unit · HP and IP lines
Removable insulation built around the parts you inspect
See the upper and lower HP / IP lines in 3D, compare bare and insulated details, then calculate what the retained heat means for electrical output, fuel, CO₂ and your own commercial case.

What changes after insulation
Benefits that operations and management can both use
The reduction percentage is only the starting point. The calculator translates it into plant impact and leaves commercial assumptions with the operator.
Outside-surface model flags when insulation thickness needs review.
Access compared with standard insulation jackets and metal cladding or boxes.
Metal bellows, flange and fasteners remain reachable without destroying the insulation.
Before and after
The same Upper HP line detail
The selected scope is the support flange together with the metal bellows directly below it.

Switch between normal and thermal visualisations, then drag the divider through bare and insulated states. These are engineering visualisations, not site thermography measurements.

What the result means
One calculation, four management views
The interface keeps engineering heat loss and plant-level outcomes connected without counting the same benefit twice.
Thermal energy no longer rejected from the selected hot surface.

Upper HP line
Support flange with metal bellows
The HP detail includes the support flange and the corrugated metal bellows directly below it.
Open explanation and calculation →
Upper IP line
Metal bellows
A separate IP-line calculation with its own reference duty and metal-bellows geometry.
Open explanation and calculation →
Lower HP line
Metal bellows
The hot lower HP detail is calculated separately from both upper lines.
Open explanation and calculation →
Lower IP line
Metal bellows
The lower IP detail starts from its own line duty and smaller metal-bellows geometry.
Open explanation and calculation →
Upper HP line
Removable module fastening detail
The fastening view explains how the insulation opens, closes and returns to the same position.

What changes the result
Why are HP and IP lines separate?
They operate at different duties. Each line keeps its own reference temperature and geometry, while temperature and number of similar elements remain editable.
Why does metal-bellows geometry matter?
A corrugated metal surface has more developed area than a flat outline. Pitch and depth therefore change the exposed area and heat-loss result.
What does up to 96% mean?
It is the public planning cap for heat-loss reduction. The useful plant results are shown alongside it: heat retained, electrical equivalent, fuel, gas, CO₂ and optional commercial value.
Is the component metal or fabric?
The HRSG component is a metal bellows. Inzonex Modular Insulation is the removable external insulation fitted around the metal component and adjoining support flange.
How is the outside-surface target checked?
The model solves heat conduction through the insulation against outdoor convection and radiation. If the result exceeds 45 °C, it asks for a thickness review.
Does insulation prove a fixed service-life extension?
No. Lower thermal exposure and easier inspection can support equipment care, but any quantified life extension needs material, stress, cycling, drainage and inspection-history data.
Method and reporting boundary
Useful numbers, with assumptions visible
Same output · less gas
The electrical output stays unchanged. Retained HRSG heat becomes a lower fuel requirement.
More electrical output
Retained heat becomes additional steam-cycle electricity. Fuel saving is not added.
Commercial values
Energy rate and installed cost stay blank until entered by the operator.
