Abstract
A glass batch preheater in one stage of which hot flue gases from a glass melting furnace are passed through a bed of cullet and a bed of glass batch material. The bed of cullet, while being heated, filters dust and other particles from the hot flue gases while the bed of glass batch materials is simultaneously heated and fluidized. An alternative preheater includes a first stage and a second supplementary stage to further heat the glass batch material. A separate stage may also be used for elutriation of glass particles. Steam may be injected to provide moisture to the glass batch and for other purposes.
