Abstract: A method and system for feeding and burning pulverized fuel, such as petroleum coke, in a glass melting furnace, which includes a glass melting and a plurality of burners associated with a pair of sealed regenerative chambers disposed side-by-side which act as heat exchangers, the burners are arranged in a series of ports that are associated with the glass melting region of the furnace. The system includes means for supplying the pulverized fuel by each one of the burners for melting glass raw materials. The emissions of flue gases produced by the combustion process of the fuel in the furnace are controlled in order to maintain clean the flue gases and for reducing the emission of impurities from the fuel such as SOx, NOx and particulates.

Abstract: Disclosed is a glassware forming mold of three-layer construction including first and third bodies, one of which is to be in contact with a portion of molten glass fed, for controlling the heat transference in a glassware forming process. A second central body is located between said first and third bodies and is comprised of a metallic alloy which melts approximately at temperature between about 375.degree. C. and 550.degree. C. corresponding to a working temperature of the molten glass, provides a solid-liquid state, to control the heat transference from the molten glass to the first or third bodies and from these to the environment during the glass forming process, whereby the glass distribution within the mold is improved.
