Dongwon Systems Glass Manufacturing with Eco-Friendly Oxy-Fuel Melting Technology

[GUNSAN, SOUTH KOREA] — Dongwon Systems’ Gunsan plant, a pioneer in the domestic packaging material industry, is capturing intense market attention by transitioning its core glass-melting process entirely to advanced “Oxy-Fuel” combustion technology. By implementing this next-generation method across all production lines—surpassing conventional end-port and side-port systems—the company has successfully maximized both environmental sustainability and manufacturing efficiency.

■ The Evolution of Furnace Technology

  • End-Port Type: Characterized by a pair of ports at the rear of the melting chamber where alternating combustion occurs; primarily utilized for small-to-medium-scale furnaces.

  • Side-Port Type: Features multiple ports arranged along the sides of the melting chamber to increase thermal output; highly suitable for large-scale operations and flat glass production.

  • Oxy-Fuel Type: A state-of-the-art method that supplies highly concentrated oxygen (90–98% purity) instead of standard atmospheric air, maximizing combustion and thermal efficiency to the absolute highest standard.

■ Core Achievements of Oxy-Fuel Implementation (ESG Impact)

The complete integration of Oxy-Fuel melting technology yields three critical operational and environmental breakthroughs:

  • Uncompromising Environmental Sustainability: By eliminating ambient nitrogen from the combustion process, Nitrogen Oxide (NOx) emissions are drastically minimized. This effectively prevents atmospheric pollution at the source, eliminating the need for costly secondary post-treatment or exhaust filtration facilities.

  • Maximizing Energy Efficiency & Cost Savings: The exceptional thermal transfer rate substantially cuts fuel consumption compared to conventional regenerative methods, significantly sharpening the company’s manufacturing cost competitiveness.

  • Extended Equipment Lifespan: The optimized combustion environment minimizes structural stress and limits the aging rate inside the furnace, successfully prolonging overall equipment longevity.

■ Strategic ESG Management and Global Outlook

Through aggressive technical refinement, Dongwon Systems has successfully overhauled its legacy configurations—previously operating as end-port types for Furnaces No. 1 and 5, and a side-port type for Furnace No. 3—into a fully integrated, state-of-the-art Oxy-Fuel melting system across Furnaces No. 1, 2, and 3.

This comprehensive transition transcends a mere facility upgrade; it represents a decisive corporate commitment to driving ‘Low-Carbon Green Growth’ in a demanding global ecosystem.

Industry experts project that this proactive, eco-friendly investment will serve as a powerful competitive edge, further consolidating Dongwon Systems’ leadership in the global packaging market amid increasingly stringent international environmental regulations.
