Benefits

Improved Operation of the Pulverizer

The MagMill

·         Will reduce wear in the pulverizer and in all equipment touched by coal downstream of the pulverizer

·         Will reduce power draw by the pulverizer

·         Will deliver a better quality fuel to the furnace

·         Will increase the output of the pulverizer

Reduction of Ash

The MagMill

·         Will increase the capacity of an existing ESP

·         Will reduce slagging in furnace and superheater

·         Will reduce amount of ash for deposition

·         Will reduce amount of popcorn ash generated

Removal of Sulfur

The MagMill

·         With an existing FGD, will reduce amount of chemicals needed to meet SO₂ emission requirement

·         With no FGD in place, will reduce capital cost of the FGD needed and reduce the amount of chemicals needed

·         Will increase the amount of SO₂ credits received

·         Will lower the FGD sludge disposal cost

·         Will allow for deeper staging to reduce NO_x generation

·         Will reduce tube wastage and unit down time

Removal of Trace Metals

The MagMill

·         Will lower cost of post-combustion mercury removal

·         Will increase the life of SCR catalysts

·         With an existing ACI, will reduce amount of activated carbon needed to meet the mercury emission requirement

·         With no ACI in place, will reduce capital cost of the ACI needed and reduce the amount of activated carbon needed

·         Will increase the amount of Hg credits received

Combined with NalcoMobotec’s FSI (furnace sorbent injection) to Reduce SO₂

·         The MagMill has removed up to 50% of the sulfur before combustion

·         FSI will remove 60% of the SO₂ in the flue gas by limestone injection

·         Combination can result in over 70% of the SO₂ removed without the capital and operating costs associated with FGD
