Oxy-fuel accelerated glass melting furnace and method of operation
Abstract
Abstract THIS SPECIFICATION DISCLOSES A METHOD AND APPARATUS FOR RAISING THE TEMPERATURE OF THE GLASS IN A GLASS-FINING FURNACE WITHOUT PRODUCING A CORRESSPONDING INCREASE IN THE TEMPERATURE OF THE CROWN OF THE FURNACE. THE IMPROVED RESULT IS OBTAINED BY USING AUXILIARY HEAT FROM AN OXYFUEL BURNER FLAME PROJECTED INTO THE FURNACE AS A NONLUMINOUS FLAME, HAVING LOW RADIATION. THE FLAME IS PROJECTED IN THE DIRECTION OF THE GREATER LENGTH OF THE FURNACE AND FROM A LEVEL ABOVE THE GLASS AND DOWNWARD AT AN ANGLE WIHICH PERMITS THE COMBUSTION OF THE BURNER FLAME TO BE SUBSTANTIALLY COMPLETE BEFORE THE PRODUCTS OF COMBUSTION OF THE FLAME JET BRUSHES THE TOP SURFACE OF THE MOLTEN GLASS. HEAT IS TRANSFERRED FROM THE PRODUCTS OF COMBUSTION TO THE GLASS MAINLY BY CONVECTION.
