Abstract
An oxygen-fuel burner has a pipe 20 for fuel, for example pulverized coal carried in air, and two pipes 22 and 24 for oxygen. The burner is typically mounted horizontally above a burden to be heated. The oxygen pipes 22 and 24 have separate outlets disposed such that the flame is caused to curve towards the burden. The relative rates of supply of oxygen to the two passages are varied so that the flame is moved across at least part of the burden.
