Disclosed is a method for manufacturing glass, and apparatus for effecting same, which comprises passing flue gases from a glass melting furnace through a bed of agglomerates of glass forming batch materials so as to heat the agglomerates to a temperature less than that at which they form an aggregated mass, cooling the flue gases as they pass through the bed with a heat exchanger positioned in the bed, and then melting the heated batch materials in a fossil fuel fired melter to form molten glass. The heat transfer medium of the heat exchanger may then be transported to a different location and the increased energy therein employed for a beneficial purpose.

In a glass manufacturing method comprising: converting glass-forming batch ingredients into agglomerates, heating a bed of said agglomerates in a chamber by direct contact with flue gases so as to produce non-aggregated agglomerates, said flue gases originating in a glass melting furnace and having been cooled in a heat exchanger prior to said direct contact heating, and discharging said heated agglomertes to a glass melting furnace; the improvement comprising indirectly extracting heat from said flue gases during said heating in said chamber. In a glassmaking apparatus comprising: means for converting glass-forming ingredients into agglomerates, a combustion-heated glass melting furnace, means for cooling combustion gases, chamber means for preheating a bed of said agglomerates by direct contact with the combustion gases of said furnace, means for transporting agglomerates from said converting means to said chamber means, means conveying combustion gases from said furnace to said combustion gas cooling means then to said chamber means, and means for conveying preheated agglomerates from said chamber to said furnace; the improvement comprising heat exchange means disposed in said chamber for indirectly extracting heat from said combustion gases.
