a yield loss. If reducing conditions are approached, the
organics will not be completely oxidized and elemental
sulfur will form, which will sublime and block down-
stream equipment as the gases are cooled. Application
of oxygen combustion burners to a SAR furnace with
its highly corrosive atmosphere posed particular prob-
lems. Especially, it was necessary to ensure that suf-
cient mixing occurs and that kinetics of the various
decomposition reactions are not adversely affected by
the use of pure oxygen.
At the start of the development program, it was not
known whether the oxy/fuel burners could provide
the required mixing and ...
