Abstract
The present invention is directed to a method of making such gypsum panel. For instance, the method comprises: providing a first facing material; providing a gypsum slurry including calcium sulfate hemihydrate, water, and a silicon containing compound onto the first facing material; providing a second facing material onto the gypsum slurry to form a continuous gypsum sheet; allowing the calcium sulfate hemihydrate to hydrate to form calcium sulfate dihydrate; cutting the continuous gypsum sheet to form a gypsum panel; supplying the gypsum panel to a heating or drying device; and providing a gaseous mixture from the heating or drying device to a regenerative thermal oxidizer.

A method of making a gypsum panel, the method comprising:
- providing a first facing material;
- providing a gypsum slurry including calcium sulfate hemihydrate, water, and a silicon containing compound onto the first facing material;
- providing a second facing material onto the gypsum slurry to form a continuous gypsum sheet;
- cutting the continuous gypsum sheet to form a gypsum panel;
- supplying the gypsum panel to a heating or drying device;
- and
- providing a gaseous mixture from the heating or drying device to a regenerative thermal oxidizer, wherein a silica particulate emission in the gaseous mixture prior to entering the thermal oxidizer is 0.035 gr/dscf or less.
