The invention discloses a bubble melting method in float glass production. Two sets of bubblers are arranged in a furnace tank of a melting part of a float glass melting furnace, so that the temperature of the flame space of the melting part is 1390-1410 DEG C; each set of the bubblers are respectively arranged along the width direction of the melting part; the number of the bubblers in each set is 10-20; the distance between every two adjacent bubblers is 650-680mm; the distance between the nozzle of each of 30-50% of the bubblers in the middle of the each set and the glass level is 440-465mm, and the flow rate of the introduced gas is 0.3-0.39 m<3>/hour; the distance between the nozzle of each of the rest bubblers and the glass level is 470-500mm, and the flow rate of the introduced gas is 0.4-0.5 m<3>/hour; the distance between the two sets of bubblers is 1100-3100mm; and the two sets of bubblers are respectively arranged 3.1-5.5mm from the lower reach of the bubble borderline, and are 2.8-4.5m away from the material mountain, wherein the combustion-supporting air blowout position of the melting part is avoided.
