In 2008, Guardian Industries conducted their second cold tank repair on their Kingsburg, CA float glass plant. Changes to the operations included installation of Lowest Achievable Emission Rate (LAER) air quality control (AQC) technology. New regulations for glass furnaces adopted by the San Joaqun Valley Unified Air Pollution Control District required the replacement of the existing electrostatic precipitator for particulate control with a new and modern Air Quality Control (AQC) system for reduction of SOx, particulate matter, and NOx. The AQC system was commissioned mid-2008 and is successfully melting initial permit emission limits. This paper describes the AQC plant supplied by GEA Bischoff, and performance data are given. It should be noted that the NOx reduction stage is the first application in the US.
