• To understand SO_2 oxidation mechanism in boiler furnaces and to examine its factors quantitatively, the effects of coal type and combustion stoichiometry on SO3 formation have been investigated by conducting tests at 1.6MWth pilot plant having a test section simulating a horizontal tube bank. SO_3 concentration was high for coals containing high amounts of sulfur and vanadium oxides. SO_3 concentration decreased linearly with decreasing O_2 concentration. Reduction of combustion stoichiometry from 1.5 to 1.2 decreased SO_2 oxidation rate from 1.4 to 0.6% and from 2.4 to 1.0% for high sulfur coal and 40% petroleum coke blend, respectively. Our results are consistent with some field data and also significant for quantifying the effects of operating conditions on reducing SO_3.
