CONTROL OF GAS CIRCULATION IN GLASSMAKING FURNACE Russian patent published in 2017 - IPC C03B5/04 

FIELD: glass.

SUBSTANCE: group of inventions relates to glassmaking furnace operation methods. Method consists in fact, that glassmaking material is melted in glassmaking chamber melting zone for producing of melted glassmaking material bath due to heat, supplied to melting zone above bath during fuel combustion and preheated oxidizer from two or more pairs of regenerator opposite holes in glass melting furnace side walls, where when combustion atmosphere is created containing combustion products above bath in melting zone. Then passing melted glassmaking material from melting zone inside and through glassmaking chamber refining zone, and then from glassmaking chamber through opening in front wall without combustion of fuel and oxidizer in refining zone over melted glassmaking materials. After that introducing gas flow or sprayed fluid medium into refining zone above molten glassmaking material either simultaneously from pair of opposite injectors, arranged on refining zone opposite side walls, or alternately from each injector, included in said pair of opposite injectors, in direction to refining zone other side wall. If said flows are introduced simultaneously, ratio of sum of flames flows full amount from pair of regenerator opposite openings, closest to front wall, and total amount of flows from one of injectors to total amount of flows from another injector is from 0.25 to 3.0. If said flows are introduced alternately, number of gas or sprayed fluid media flow, which come from such injector, ranges from 25 to 300 % relative to amount of flame flows from regenerator opening, with sufficient amount of flow for combustion products flow reduction from melting zone into refining zone.

EFFECT: technical result is reduced corrosion of refractory materials and higher quality of molten glass.
