GLASS MELTING FURNACE, GLASS MELTING METHOD AND METHOD FOR MANUFACTURING GLASS

摘要

PROBLEM TO BE SOLVED: To provide a glass melting furnace capable of controlling the combustion output of a burner each time according to increase and decrease in the production volume of glass in a side port type glass melting furnace.SOLUTION: A glass melting furnace 1 comprises: a melting chamber 10 for melting a glass raw material; a heat storage chambers 13, 14 provided on both sides of the melting chamber 10 and for collecting the heat of combustion exhaust gas to preheat combustion air; a plurality of ports 11, 12 for coupling the melting chamber 10 and the heat storage chambers 13, 14; and burners 15, 16 provided in the respective port 11, 12. In the glass melting furnace supplying the combustion air through one of the heat storage chambers for each predetermined time to burn fuel by the burners 15, 16 and exhausting combustion exhaust gas through another of the heat storage chambers 13, 14, at least one of nozzles 17, 18 is provided between the heat storage chambers 13, 14 and the burners 15, 16 in the plurality of ports 11 and 12, and the nozzles 17, 18 are provided so as to blow air in the directions opposite to the directions of the flames of the burners 15, 16.SELECTED DRAWING: Figure 1
