An apparatus and method are disclosed for processing glass-making materials under oxidizing conditions, and for processing materials, such as hazardous or toxic wastes, or smelting under reducing conditions. As a glass-making apparatus the invention includes a cyclone melt reactor for forming a liquid glass melt and a combustion preheater for receiving the glass-making materials and combusting the fuel and oxidant therein to heat the glass batch materials to a temperature at least equal to the melt temperature of the glass batch material. The combustion preheater has an outlet connected to the glass melt reactor, and at least one inlet is provided into the combustion preheater for introducing oxidizing materials and for creating a well-stirred region within the combustion preheater means. Supplemental heat can be provided by introducing a heated transfer gas into the combustion preheater, and a fuel gasifier can be provided for producing a fuel gas before the fuel gas is injected into the combustion preheater. For processing materials under reducing conditions, the cyclone melt reactor is connected to a preheater/reducing chamber and preheated reducing gas is introudced into the reducing chamber in such a manner that a well-stirred region is created within the reducing chamber. Heated transfer gas from a supplemental heat source and reducing gas from a fuel gasifier can also be introduced into the reducing chamber.

An apparatus for producing glass from glass batch materials, in the presence of a fuel and oxidant, said apparatus comprising: cyclone glass melt reactor means for forming a liquid glass melt; combustion preheater means for receiving said glass batch materials, fuel and oxidant and combusting said fuel and oxidant therein and heating said glass bat h materials to a temperature at least equal to the melt temperature of said glass batch materials, said combustion preheater means having an outlet connected to said cyclone glass melt reactor means; and inlet means for injecting said oxidant into said combustion preheater means and creating a counter rotating well-stirred region within said combustion preheater means. A method of treating materials for delivery to a cyclone melter having an inlet and an outlet, said method comprising the steps of: connecting a suspension-type cylindrical combustion preheater to the inlet of said melter, said preheater having a vertically oriented longitudinal axis and an upper and a lower end, introducing a first material into said preheater; introducing a fuel into said preheater; and introducing a preheated oxidant into said preheater so as to create a counter rotating, turbulent mixture of said fuel, said oxidant and said first material within the upper end of said preheater, whereby a well-stirred region of said oxidant, said first material and said fuel is created in the upper end of said preheater.
