PentoMag® | Additive for Coal Boilers - Pentol

Anti slagging additive for coal fired boilers. PentoMag 2550 increases the fusion temperature of metals in fly ash. Thus preventing that ash can stick to the boiler walls. It changes the amorphous structure by forming friable crystals with low density. Their removal will usually lower the maintenance.
