PCT No. PCT/GB90/00716 Sec. 371 Date Jan. 10, 1992 Sec. 102(e) Date Jan. 10, 1992 PCT Filed May 9, 1990 PCT Pub. No. WO90/13522 PCT Pub. Date Nov. 15, 1990.A method of feeding and firing a glass-melting furnace comprises the step of passing glass batch, combustion air and burning fuel vertically down a cylindrical tower and through the crown of the furnace. A feed stream of glass batch and combustion air is surrounded by burning fuel in the tower and the flame of burning fuel strikes the surface of molten glass in the furnace. Infra-sound waves are applied to the glass batch, combustion air and burning fuel as these are fed downwardly through the tower and the crown of the furnace to enhance transfer of heat from the burning fuel to the glass batch so that the batch in the feed stream is heated to melting temperature and molten glass droplets fall upon the surface of molten glass in the furnace.
