The float glass melting tank is huge and complex equipment which the operation parameters are difficult to control in production line. The install of desulfurizer makes the kiln more complex and unstable. In present work, we fulfill the field experiments and obtained the optimal practical operation parameters. The obtained parameters were: aperture of wings gate: 75-85%; aperture of draft fan: 30-35% for draft fan 1, and draft fan 2 were through-type; aperture of conveying fan: 70-85%; temperature of gas into desulfurizer: 180-200°C; the water flow were controlled by thermocouple and diaphragm control valve; Velocity of gas into desulfurizer: 8-10 m/s. Our results provide the guidance for installing the desulfurizer and modifying the whole system in practice.
