METHOD OF MELTING OF THE GLASS-FORMING MATERIAL IN THE GLASS MELTING FURNACE AND THE OXYFUEL BURNER Russian patent published in 2006 - IPC C03B5/00 

FIELD: glass industry; methods of the glass-forming material melting in the glass-melting furnace and the oxyfuel burner.

SUBSTANCE: the invention is pertaining to the oxyfuel burners mounted in the roof of the glass-melting furnace. The technical result of the invention is the increased production of the glass, the improved quality of the glass, the decreased power consumption, recovery of the productive capacity, the reduced utilization of oxygen. At least one step-by-step oxyfuel burner is mounted in the roof of the glass-melting furnace. The spray of the injectable fuel and the spray of the injectable oxidizing agent are parted and form the angle in respect to each other from 0° up to 90°. The fuel burning conduct in such a manner, that a part of the burning happens near to the glass-forming material for magnifying of the convective and radiant transfer of the heat to the glass-forming material. The oxyfuel burner contains at least one external injector of the oxidizing agent and two internal injectors of fuel. The central injector of the fuel is intended for injection of the fuel with the high speed, and one ring-type injector of the fuel is intended for injection of the fuel with the low speed. The central injector of the fuel is intended for provision of the central spray of the high-pressure fuel containing at least one gaseous fuel or the liquid fuel. The ring-type injector of the fuel is intended for provision mainly the annular fuel shell of the more low pressure containing the gaseous fuel outside the concentrically with respect to the central jet of the fuel.

EFFECT: the invention ensures the increased production of the glass, the improved quality of the glass, the decreased power consumption, recovery of the productive capacity, the reduced utilization of oxygen.
