METHOD FOR HEATING A LOW-NOx GLASS FURNACE HAVING HIGH HEAT TRANSFER

摘要

The invention relates to a method of heating molten glass by a furnace (1) comprising side walls fitted with transverse burners and provided with regenerators (4, 13), characterized in that at least one burner is fed with oxidizer comprising less than 30 vol % oxygen and with fuel in such a way that the oxidizer momentum/fuel momentum ratio ranges from 5 to 13. This operating mode provides excellent heat transfer to the glass and generates little pollution.
