Abstract: A particle suspension furnace (10) having an upper injector section (11), an intermediate combustion section (12) and a lower separation section (13). The injector section (11) 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 NOx pollutant formation.
