Abstract: Disclosed is a method for utilizing the by-product of a board plant in production of a synthetic gas (referred to as "syngas"). The syngas produced by way of the present invention can then be utilized within the board plant to, thereby, reduce the amount of natural needed. The method utilizes the heated water vapor (H 2 0) and carbon dioxide (CO 2 ) found within the flue gas of a board dryer. The H 2 and CO 2 are used in a gasification process to yield the syngas.

Abstract: The present invention relates to an improved method for using heat energy in a gypsum board plant. More specifically, the method contemplates taking heat from a gasifier, or other alternative heat source, and using it to dry gypsum boards. In order to control humidity levels, this heat is delivered to one or more board dryers via a heat exchanger.

Abstract: Disclosed are various methods for reducing levels of elemental sulfur within gypsum products such as wall board. Gypsum sometimes includes increased levels of elemental sulfur. Such sulfur can be corrosive and otherwise harmful at elevated levels. The disclosure contemplates reacting the elemental sulfur with copper to copper sulfide. This reaction has the benefit of reducing the levels of elemental sulfur present within the final gypsum product. The copper can be added at any of a variety of locations in the manufacturing process. This is a very efficient method for reducing elemental sulfur in the production of gypsum products.

Abstract: The present invention relates to a system and method for the production of gypsum board using starch pellets. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. The pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase. This both provides the desired starch component and also results in the formation of voids within the set gypsum.
