The utility model discloses a hollow glass micro-balloon burner. A feed pipe (3), a gas pipe (4) and a combustion-supporting gas pipe (6) which are sequentially and coaxially sleeved form a burner nozzle; one end of the combustion-supporting gas pipe is connected with a burning pipe (5); and the side lower parts of the gas pipe (4) and the combustion-supporting pipe (6) are respectively provided with a gas inlet (2) and a combustion-supporting air inlet (1). The utility model has the advantages that because the glass micro-balloons are in the same flow direction as the burning gas flows, glass micro-balloon particles are molten in the burning flame and then only flows vertically upwards under the action of a terminal draft fan; therefore, the molten glass micro-balloons are avoided from colliding a furnace wall or other devices, so that the generation ratio of glass micro-balloons is improved and the color and the roundness are greatly improved. The burner has simple structure, can use various low-price coal gases, and have stable combustion and little equipment investment.
