Abstract
1,067,006. Glass melting furnaces. LIBBEYOWENS-FORD GLASS CO. June 10, 1965, No. 24513/65. Heading F4B. Crystalline scale formation on the roof and side walls of the refining zone of a glass melting furnace is turned into a sticky mass of sodium silicate by injecting a flux comprising a sodiumsulphur compound into the furnace near the given zone and maintaining a controlled reducing atmosphere therein. The flux may be a water solution of sodium sulphate and the reducing atmosphere supplied by a gas such as CO, H 2 , SO 2 and dissociated NH 3 or hydrocarbon. A water-soluble organic sodium-sulphur compound may be mixed with the sodium sulphate, examples of such compounds being A sodium alkyl sulphate; A sodium alkyl sulphonate; The disodium salt of a sulphated fatty acid; A sodium fatty acid ester sulphonate ; A sodium fatty acid amide sulphonate; A sodium secondary alkyl sulphonate; A sodium aryl sulphonate; A sodium salt of the bisulphate of a dialkyl dicarboxylate; and A sodium salt of the sulphonic acid derivative of a dialkyl dicarboxylate. Good results have been obtained by utilizing a mixture of three parts by weight of water with equal parts by weight of Na 2 SO 4 and either Sodium lauryl sulphate paste; or The oleic acid ester of sodium isothionate; or A dioctyl ester of sodium sulphosuccinic acid. The solution is sprayed over the appropriate furnace parts through lances in a stream of pressure air or steam.
