ABSTRACT:
The invention relates to various energy saving measures for use in the smelting, refining and melting of metals, and in particular in the manufacture of steels, alloy steels and ferrous alloys. In such processes fuel consumption is reduced and efficiency improved by using in the oxy-fuel or air-fuel burner a fuel (referred to as an "X-type" fuel) which has an exothermic heat of decomposition or which has only a zero or a very small endothermic heat of decomposition.
The invention also relates to an oxy-fuel or air-fuel burner for use in a metallurgical process using an X-type fuel, which burner uses as coolant for the burner walls and tip the fuel used in the burner.
