Abstract
Combustion of refuse-derived fuel (RDF) alone or together with other
biomass leads to superheater fouling and corrosion in efficient power
plants (with high steam values) due to vaporization and condensation of
alkali chlorides. In this study, means were found to raise the portion
of RDF to 40% enb without risk to boilers. This was done by co-firing
RDF with coal and optimizing coal quality. Free aluminum silicate in
coal captured alkalies from vaporized alkali chlorides preventing Cl
condensation to superheaters. Strong fouling and corrosion were
simultaneously averted. Results from 100 kW and 4 MW CFB reactors are
reported.
