Abstract
A particle suspension furnace having an upper injector section, an intermediate combustion section and a lower separation section. The injector section comprises a central fuel conduit for supplying a rich fuel/air mixture to a burner at the base of the injector section, and a concentric annular mixing chamber for supplying a mixture of reactive or meltable batch particles and oxygen to the burner. The fuel-rich burner flame diffuses radially-outwardly to consume the peripherally-supplied oxygen and form an oxygen/fuel combustion mixture having a predetermined selected stoichiometry which is variable above and below 1:1 stoichiometry depending upon whether a reducing or oxidizing atmosphere is desired. The suspended particles absorb heat to quench the burner temperature and reduce the NO.sub.x pollutant formation.
