PPG’s Fresno, Calif., glass plant, which suspended operations in January for a furnace reline and refurbishment, resumed production April 1.
The 50-year-old facility, which makes clear and Starphire ultra-clear glasses in 2.5- to 12-millimeter thicknesses, has been idle since early January for scheduled maintenance after more than 15 years of continuous manufacturing. Ray Yee, Fresno plant manager, says the project will primarily benefit customers in the western U.S. and western Canada.
The plant typically produces 650 tons of glass per day using proprietary oxygen-fuel technology, according to PPG.
“This process combusts glass raw materials such as sand and silica using oxygen instead of air, reducing natural gas consumption by 15 percent, carbon emissions by 10 percent and nitrogen-oxide emissions by more than 50 percent compared to traditional air-fired glass furnaces,” a release from the company reads.
Yee says glass plants typically complete furnace reline projects every ten to 15 years to replace worn refractory brick. He added that the Fresno project also covered plant-wide maintenance, including upgrades to the mechanical and electrical systems.
