In float glass production the molten tin bath is protected from oxidation by a protective atmosphere of nitrogen and hydrogen. Oxygen-enriched combustion in melting furnaces lowers fuel consumption. Raw materials such as sand, soda and cullet are fed dust-free and enclosed by pneumatic conveying systems.

A float line depends on a stable N2/H2 atmosphere over the tin bath: any oxygen ingress causes tin oxide defects on the glass surface. On-site nitrogen and hydrogen generators supply this atmosphere at constant composition without relying on bulk deliveries. In the melting end, oxygen generators allow oxygen-enriched or oxy-fuel firing, and dense phase conveying moves abrasive sand, soda and cullet at low velocity, which limits pipe wear and dust. Circulation pumps serve the cooling water circuits. For a proposal, provide gas flows and purities, furnace capacity, batch materials with conveying distances and tonnages, and cooling water flow rates.
