Burner Selection
| Stage | Traditional | AI Automation |
|---|---|---|
| Input | Fuel type, furnace duty, manual CFD setup | Process data, historical furnace performance, AI-guided inputs |
| Burner Screening | Dozens of CFD runs | AI surrogate models shortlist 2–3 burner designs |
| Furnace Matching | Trial-and-error with CFD & test data | AI suggests best burner-furnace pair automatically |
| Validation | Long CFD + physical test | AI-CFD hybrid + minimal validation tests |
-
AI Automation:

Generative Design (AI-based): AI proposes burner geometries (swirlers, nozzles, air-fuel mixing designs).
-
Surrogate Models: AI trained on CFD + test data can instantly predict flame length, emissions, efficiency.
-
Optimization Engine: AI evaluates trade-offs (low NOx vs. stable flame vs. high heat flux) and recommends best-fit burner.
-
Fuel Flexibility Analysis: AI quickly tests how burners behave with natural gas, hydrogen blends, syngas, or biomass.
-
Result: AI narrows burner options from 100s to a few best-fit designs before final CFD validation.
| Aspect | Traditional Approach | AI-Automated Approach |
|---|---|---|
| Data Handling | Manual collection of process, fuel, and test data; prone to gaps/errors | Automated integration of process, test, and CFD data; continuous updates from sensors/IoT |
| Design Screening | Engineers manually shortlist burners/furnaces from catalogues & past experience | AI searches databases and past case libraries; instantly ranks suitable options |
| Simulation & Analysis | Multiple full CFD runs → high cost & time | AI-CFD surrogate models predict performance in minutes with fewer full CFD validations |
| Optimization | Trial-and-error geometry testing; limited to few cases due to cost/time | Multi-objective AI optimization → evaluates 1000s of designs for efficiency, emissions, and cost |
| Validation | Requires extensive experimental testing | AI auto-calibrates CFD using test/process data; reduces need for repeated experiments |
| Time Required | Weeks to months for final selection | Hours to days for final recommendation |
| Accuracy | Dependent on engineer expertise + CFD assumptions | Improves with AI learning from large datasets; adapts continuously with real plant data |
| Fuel Flexibility | Separate analysis needed for each fuel type | AI models predict performance across multiple fuels (NG, hydrogen blends, biomass, syngas) quickly |
| Decision Support | Human expertise is primary driver; subjective judgment plays a big role | AI provides data-driven ranking & reports; engineers focus on final approval |
| Cost | High engineering + CFD simulation + testing costs | Lower costs due to reduced CFD runs, faster screening, fewer physical tests |
