Thermal Loss Diagnostics for Boilers, Furnaces & Steam Systems
Industrial boilers, furnaces, steam lines, and heat-transfer systems operate under extreme temperatures. When insulation or refractory materials fail, the resulting thermal losses directly increase fuel consumption, degrade system efficiency, and introduce serious safety risks.
Enisave Solutions performs detailed thermographic imaging on steam lagging, boiler shells, high-temperature piping, heat exchangers, and furnace casings. Each survey follows **ISO 18434-1 (Thermography for Condition Monitoring)** and **ISO 50001 (Energy Management)** methodologies to quantify heat loss and prioritise corrective maintenance.
Systems We Inspect
- Steam lines (main distribution & process feed)
- Boiler shells, doors, expansion joints & manways
- Furnaces, CAB units, flux driers, refractory casings
- Condensate return lines & heat exchangers
- Valves, flanges, traps & steam fittings
- Insulation lagging (mineral wool, calcium silicate, ceramic fibre)
Common Defects Identified
- Insulation saturation or missing lagging
- Refractory breakdown / furnace wall hotspots
- Steam leaks, gasket failure & flange losses
- Poor insulation thickness / degraded cladding
- Heat loss through boiler seams & access doors
- Damaged or corroded pipe lagging
Why Thermography for Steam Systems?
Steam distribution and boiler systems lose significant energy due to insulation defects. A single metre of uninsulated 150°C pipe can waste up to:
- **850–1,200 W/m of continuous heat loss**
- **R 400–R 1,200 per month per defect**, depending on fuel type
Thermal imaging quantifies these losses without shutting down production, enabling targeted insulation repairs where the ROI is highest.
Energy Loss Calculation Method
Enisave applies the **ISO 50001 Option B estimation method**, including:
- Surface temperature measurement
- Ambient reference temperature
- Emissivity modelling
- Heat transfer coefficient estimation
This enables approximate kW loss, annual energy waste, and financial impact calculation.
