New material industry(Float glass)

Gases widely used in glass industry include hydrogen, acetylene, oxygen and nitrogen. There is molten tin liquid in float glass forming equipment. It is easy to be oxidized to form tin oxide, which causes tin staining and increases the consumption of tin. Therefore, it is necessary to seal the tin tank and continuously send a pure mixture of hydrogen and nitrogen to maintain the positive pressure and reduction atmosphere in the tank to protect the tin from oxidation. Hydrogen consumption in float glass plant depends on production scale. Generally, it is between 80-150 m3/h. Hydrogen supply mode is usually electrolytic hydrogen purified and sent to tin tank. The purity of hydrogen is 99.99%.
