| Abstract |
The atmospheric emissions that are produced during the operation of calcining gypsum and production of gypsum board products are studied. The average particulate emissions from these plants are between 25 and 40 pounds per hour with baghouse collectors and electrostatic precipitators generally being employed as control devices. Emission of sulfur oxides is primarily dependent upon the sulfur content of the fuels being used for calcining and other operations, and production of nitrogen oxides is also a function of the combustion equipment and fuels used. Emission regulations relating to visible, particulate, sulfur oxide, and nitrogen oxide emissions are shown for nine states. A description of a general process for production calcined gypsum and gypsum board products is given with flow diagrams. A list of gypsum and/or gypsum product producers is shown along with total industry production capacity, best controlled plants and their control equipment, and emissions data from various production locations. A brief description of emission analysis, applicable control technology, and economics of control equipment is included. (Modified author abstract) |
