Abstract
An end-fired melting furnace and a method of melting raw materials by an end-fired melting furnace are provided, where the furnace includes a melting tank, a melting chamber, first and second ports, at least one burner, and at least one auxiliary fuel injector arranged in the end-fired melting furnace in a roof or in first and second side walls so that the at least one auxiliary fuel injector introduces a fraction X2 of auxiliary fuel, in a direction of re-circulating combustion products, without additional oxidiser, into the re-circulating combustion products in a direction of a flow of the re-circulating combustion products, and with a chosen velocity such that the fraction X2 of auxiliary fuel mixes with the re-circulating combustion products before being combusted by oxidiser entering the furnace.
