ABSTRACT:
Volatile borates and/or fluorides are removed from the hot stack gases of a glass furnace by passing the hot stack gases up through a layer of wet pellets containing ions of an alkaline earth metal or an alkali metal. The pellets may contain solid borates and/or fluorides as part of the feed to the glass furnace, and still absorb volatile materials from the stack gases, so long as the borates and/or fluorides in the pellets are in, or are converted to a less soluble and volatile form that are the volatile materials in the stack gases. Ca(OH).sub.2 is a preferred material for converting the volatiles into an essentially nonvolatile form. Ion exchange materials, such as clay, can also be used to capture these volatiles.
