Control of SO3 in low-pressure heating boilers by an additive: M38-8/79E-PDF
"This paper deals with the burning of residual fuel oil containing 25% sulphur under conditions prevalent in heating boilers to assess the effect of boiler load, excess combustion air, mean residence time and the use of a magnesia-alumina fuel-oil additive on the formation of noxious and corrosive products of combustion. Results show that the additive can be used as an effective substitute for low excess combustion air in reducing the emission of oxides of nitrogen and SO3. Furthermore, the additive neutralizes condensed H2SO4 and improves the electrical resistivity of soot particles to the point where electrostatic precipitation of soot is technically feasible. Detailed analyses of particulate matter samples taken from flames with untreated oil and oil treated with three different amounts of additive are described to elucidate the mechanism of acid soot neutralization and to obtain data on soot constituents that may contribute to atmospheric pollution. It is shown that the standard methods for measuring SO3 concentrations in flue gas can give misleading results when soot or particulate matter is present"--p. 67.
