A New Process of Glass-melting by Introducing Flames into the Molten Glass

JSGT 1955 V39 T162-T172

The thermal efficiency of glass-melting is improved by infusing the fuel, air and gas which are previously compressed, into the mass of molten glass; and a flame-injection furnace incorporating this principle of firing is described. Importance is attached to conservation of heat, of which full use is made by feeding the batch in the form of a spray through the exhaust gases. A sandspray heat exchanger, reaching an efficiency of 60%, is described. Results are given of experimental plant trials.
