Studies in the Distribution of Temperature through Molten Glasses in a Tank Melting Furnace. Part I. Laboratory Measurements on Some Commercial Glasses

JSGT 1945 V29 T005-T034

A heat balance for the furnace was drawn up, and the overall heat transmission through the molten masses of three types of glass were calculated from temperature gradient measurements carried out for a constant heat input of 12 cu. ft. per min., the temperatures developed at the centre of the glass surface being, respectively, 1400°, 1435° and 1462° for the colourless, amber and dark green glasses. The overall transmissions were 60% for the colourless, 49% for the amber and 37% for the dark green glass.
