FIELD: process engineering.
SUBSTANCE: invention relates to glass melting furnaces. Glass melting furnace comprises melting vessel shaped to melting channel wherein stock is loaded at upstream end while fused glass results at downstream end. Note here that said furnace is heated by burners wherein at least 80% of combustion energy results from oxygen combustion. Note here that oxygen is continuously fed from industrial plants located nearby or connected via pipelines. Note also that said furnace is equipped with oxygen storages to allow furnace operation under emergent conditions for at least 8 hours and, preferably, 20 hours, most preferably, for 30 hours. Note that power produced by burners under emergent conditions equals not over one third of power under normal operating conditions.
EFFECT: glass crystallisation ruled in furnace operation under emergent conditions.
