Studies of the Fate of Sulfur Trioxide in Coal-Fired

The formation of (SO 3) in utility boilers can have negative effects on performance and operation such as fouling and corrosion of equipment efficiency loss in the air preheater (APH) increase in stack opacity and the formation of PM 25 can also compete with mercury when bonding with injected activated carbons

US20030027014A1 - Low sulfur coal additive for improved

The present invention is directed to for -fired furnaces particularly furnaces using a layer of slag to capture particles for combustion The (s) include iron mineralizer(s) handling aid(s) flow aid(s) and/or abrasive material(s) The iron and mineralizers can lower the melting temperature of ash in low-iron high alkali coals leading to improved furnace

US5122353A - Reduction of sulfur emissions from coal-fired

It is a more specific object of the invention in one embodiment to enable the increased reduction SOxfrom an existing in part through the achievement of an increased ratio of

Studies of the fate of sulfur trioxide in coal-fired

The formation of trioxide (SO(3)) in -fired utility can have negative effects on performance and operation such as fouling and corrosion of equipment efficiency loss in the air preheater (APH) increase in stack opacity and the formation of PM(25) trioxide can a

Emissions of sulfur trioxide from coal-fired power plants

Emissions of trioxide (SO3) are a key component of plume opacity and acid deposition Consequently these emissions need to be low enough to not cause opacity violations and acid deposition Generally a small fraction of (S) in is converted to SO3 in -fired combustion devices such as electric utility

Combustion Additives for Pollution Control: a State-of-the

IN FIRING Only a relatively small amount of effort has been devoted to fuel orzone to reduce oxides in systems In contrast considerable investigation has been directed to downstream addition of limestone for
