Abstract: Process and furnace for the continuous production of a molten pool from particulate meltable batch materials such as glass-forming raw materials. The raw materials, in particulate form, are injected into and suspended in combustion gases within a combustor section (19) to form a particle-laden gas flow. The gas flow is accelerated vertically downwardly into a refractory chamber (13) to impact the surface of a molten pool (15), producing inertial separation of the molten particles into the pool and strong shear forces by the exiting combustion gases, resulting in pool circulation and improved fining and homogeneity.

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.
