US5122353A - Reduction of sulfur emissions from coal-fired

The present invention is directed to additives for coal-fired furnaces, particularly furnaces using a layer of slag to capture coal particles for combustion. The additive(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

LOW SULFUR COAL ADDITIVE FOR IMPROVED FURNACE …

As will be discussed, control of mercury emissions from coal-fired boilers is currently achieved via existing controls used to remove particulate matter (PM), sulfur dioxide (SO2), and nitrogen oxides (NOX). This includes capture of particulate-bound mercury in PM control equipment and soluble mercury compounds in wet flue gas desulfurization (FGD)

Formation and Control of Sulfur Oxides in Boilers

Additives that remove sulfur trioxide from flue gas must be fed in stoichiometric quantities with respect to the amount of sulfur trioxide to be removed. Therefore, higher levels of sulfur in the fuel require higher feed rates for protection. Coal-fired boilers require less treatment than oil-fired boilers for a given sulfur …
