The Trust Well Multi-Media Soot Blower (MMSB) is a next-generation cleaning system developed specifically for Rotary/ Regenerative Air Preheaters (RAPH) in thermal power plants. Equipped with two independent blowing media — Compressed Air / Steam & Pressurised Water, it delivers unmatched cleaning effectiveness in high-ash, high-sulfur, and heavily fouled RAPH environments.
Unlike multi-nozzle or conventional soot blowers, the Multi-Media with SB eliminates the challenge of uneven purging caused by RAPH rotation, delivering a uniform, powerful cleaning strike across all baskets.
The dual media provides plant operators complete flexibility:
✔ Compressed Air / Steam for continuous soot removal (Online)
✔ Pressurised Water for targeted slag/ash deposits (Offline)
This dual capability makes it the most efficient cleaning system for RAPH surfaces in modern thermal power plants.
Designed Exclusively For:
• Rotary Air Preheaters in Thermal Power Plants
• Units experiencing:
✔ Heavy ash accumulation
✔ High-sulfur fuel slagging
✔ Uneven basket cleaning
✔ Frequent cold-end blockages
The Multi-Media LRSB provides effective cleaning across hot, intermediate, and cold-end baskets, ensuring stable APH pressure drop and maintaining boiler thermal efficiency.
✓ Superior Cleaning of RAPH Baskets
Dual-media output removes:
• Sticky ash
• Sulfur-rich deposits
• Cold-end ammonium bisulfate fouling
• Moisture-induced blockages
✓ Reduced APH Pressure Drop
Clean baskets ⇒ lower pressure drop ⇒ reduced ID/FD fan load ⇒ reduced auxiliary power consumption.
✓ Improved Boiler Heat Rate
Consistent RAPH performance enhances the thereby for overall boiler efficiency, particularly under part-load conditions.
✓ Minimal Thermal Shock
Selective water use allows cleaning only where slag is heavy, preventing thermal stress on baskets.
