Furnace Performance Diagnosis & Optimization
Diagnose furnace performance issues and optimize operating parameters
What You Can Do
You can systematically diagnose furnace underperformance by analyzing operational data (temperature profiles, gas composition, pressure drop, throughput, assay data) to pinpoint whether issues stem from feed variability, thermal loss, equipment drift, or process chemistry imbalances. The skill produces a prioritized corrective action plan validated against thermodynamic constraints, enabling you to recover metal recovery rates, reduce refractory wear, cut energy costs, and stabilize slag composition—typically within 24 hours of analysis.
Features
detect thermal anomalies and equipment drift patterns
isolate ore source, moisture, or particle size impacts on roast chemistry
calculate refractory heat loss and identify insulation degradation
verify stoichiometric equilibrium and identify flux or additive imbalances
compare cost per tonne against historical baselines and industry standards
rank fixes by impact magnitude and implementation complexity
validate recommendations against equilibrium and kinetic limits
structure findings for technical reports and process improvement initiatives
Example Output
Example 1: Metal Recovery Drop
- Symptom: Copper recovery dropped 3.2% over 2 weeks
- Analysis: Temperature profile shows 45°C deviation in roaster zone 3; assay data reveals rising iron oxide in calcine
- Root Cause: Refractory sintering in zone 3 → thermal loss → incomplete roast
- Recommendation (Priority 1): Reduce feed rate 8% and increase air/fuel ratio 12% to restore residence time; monitor zone 3 temperature daily
- Expected Outcome: Recovery return to 87.5% within 3 operating days
Example 2: Energy Cost Spike
- Symptom: kWh/tonne increased 6.8% despite stable throughput
- Analysis: Pressure drop increased 15 mbar; gas composition shows 2.1% CO₂ elevation
- Root Cause: Furnace bed settling and partial flue blockage
- Recommendation (Priority 1): Perform furnace aeration and screen buildup removal; adjust air registers ±3%
- Expected Outcome: Energy consumption return to baseline within 1 week
