Ash Fusion Temperature Chemistry
1 / 3

PentoMag 2550 — anti-slagging additive for coal-fired boilers. Increases fusion temperature of metals in fly ash, preventing ash from sticking to boiler walls.

How It Works

  • Increases fly ash fusion temperature — prevents ash sticking to boiler walls
  • Changes amorphous structure — forms friable, low-density crystals
  • Easy removal reduces maintenance frequency and cost
