CoalTreat™-500 Magnesite Ore is a specialty treatment product which has been proven effective in several areas of coal-fired utility boilers. It is typically applied to the coal prior to distribution to the burners and provides multiple benefits throughout the entire boiler system.

The magnesite ore dissociates in the combustion zone, producing highly reactive, ultra fine particles of MgO which are effective in controlling and often reducing slag formation in the furnace. Hence, boiler operations are improved and are manifest as increased heat transfer and improved efficiency (lower furnace exit gas temperatures), extended run time between outages and reduced maintenance and repairs. Another major benefit, particularly with higher sulfur coals, is the reduction of detrimental emissions of sulfur trioxide (SO₃). This reduction is often greater than 50% when CoalTreat™-500 is applied at the proper dosage level. Lower SO₃ is beneficial in reducing metal corrosion in the boiler cool zone and improves plume opacity/visible emissions (VE’s).
