| 摘要 |
<p>In processes particularly for the manufacture of steels, alloy steels and ferrous alloys 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.</p> |
