Slagging & Fouling Control
Stable Load, Higher Availability, Proven Results. TABi Energy's Slagging & Fouling Control solutions tackle one of the most persistent operational challenges in coal-fired boilers—ash deposition caused by unfavorable coal properties, high flue-gas exit temperatures, and sub-optimal sootblowing performance. Our approach combines field diagnostics, root-cause analysis, and combustion and sootblowing optimization to deliver stable operation and sustained performance improvement, even with difficult coals.
Field-Proven Benefits
Across multiple utility-scale applications, TABi Energy has achieved:
- Reduced slagging and fouling formation
- Improved load stability and operational flexibility
- Lower tube metal temperatures and thermal stress
- Reduced forced outages and cleaning frequency
- Higher boiler availability and net efficiency
All improvements are validated through long-term operating data trends.
Why Slagging & Fouling Occur
Slagging and fouling are not only caused by ash chemistry alone. TABi Energy evaluates:
- Local flame shape and heat release distribution
- Air–fuel mixing and stoichiometry
- Temperature gradients and peak zones
- Coal flow imbalance and burner interaction
This holistic diagnosis enables targeted, high-impact corrective actions.
Our solutions avoid costly full retrofits by applying:
- Improving pulverized coal fineness
- Coal flow and primary and secondary air flow balancing
- Sootblowing optimization
Delivering fast payback with low CAPEX and minimal downtime.
How We Work
This holistic diagnosis enables targeted, high-impact corrective actions across field diagnostics, root-cause analysis, and combustion and sootblowing optimization.
