Glass manufacturing process with in-situ colemanite calcination and pollution abatement features

摘要

Raw colemanite is introduced into the flue gas stream emanating in a combustion-fired furnace, which flue gas stream will contain boron values and if the glass being manufactured contains fluorine, will also containe fluorine values. This introduction provides for the calcination of the raw colemanite and likewise provides for pollution abating features by a reaction with the boron values and the fluorine values.
