||This report summarizes the results of a study to gather and analyze background information and technical data related to air emissions from glass manufacturers producing pressed and blown glassware. This includes all glassware except flat glass, glass containers, and fiber glass. The report covers emissions from three areas within the plant: raw materials preparation and handling, glass melting, and forming and finishing operations. Emissions from the melting furnace account for over 80 percent of the total plant emissions. The major pollutants are NOx, SOx, and submicron particulates consisting predominately (80%) of mineral sulfates but can also include fluoride and borate compounds. NOx has the largest emission factor (4.5 g/kg) with annual emissions 57.5 x 10 to the 9th power g. In comparison with national emissions from stationary sources, NOx emission from glass melting furnaces contributes 0.17 percent of the total. The source severity is a measure of the potential environment effect of air emissions and is the ratio of the maximum average ground level concentration compared to the primary ambient air quality standard for criteria pollutants. For this study source severity factors determined were largest for NOx, SOx, lead (PbO), and other particulates. Other emissions had a low severity factor (<0.01).
