Abstract
A process for rapid and uniform cooling of glass comprising introducing it into a fluidized bed of particles under conditions such that heat is transferred from the glass to the fluidized material. The fluidized material comprises particles which can be caused to undergo endothermic change by heating them to a temperature lower than the temperature of the glass as it enters the fluidized bed.
Claims21
A process for cooling glass comprising:
- introducing the glass into a fluidised bed of particles under thermal conditions such that heat is transferred from the glass to the fluidised material, wherein said fluidised material comprises solid particles which can be caused to undergo endothermic change by heating said particles to a temperature lower than the temperature of the glass as it enters the fluidised bed, and wherein at least some of said solid particles are particles of trihydrated alumina, activated alumina containing adsorbed or absorbed water in an amount of 20 to 30% by weight, .alpha.-Fe.sub.2 O.sub.3.H.sub.2 O, or .gamma.-Fe.sub.2 O.sub.3.H.sub.2 O.
