Combustion burner

摘要

An object of the present invention is to provide a combustion burner which is capable of heating or melting a raw material powder efficiently by dispersing the raw material powder, and which is capable of improving a collection rate of the heated or melted raw material powder, the invention providing a combustion burner that forms flame including a dispersal member which is provided in the raw material powder outlet which spouts the raw material powder into the flame, includes first and second inclined surfaces, and which disperses the raw material powder by colliding with the raw material powder that is supplied to the raw material powder outlet.

主权项

1. A combustion burner that forms flame comprising:
a raw material powder outlets which spouts a raw material powder into the flame; a plurality of first fuel outlets, which are disposed further on an inner side than the raw material powder outlets, and which spout a first fuel; a plurality of first oxidant outlets, which are disposed further on the inner side than the raw material powder outlets, and which spout a first oxidant; a plurality of second fuel outlets which are disposed further on an outer side than the raw material powder outlets, and which spout a second fuel; a plurality of second oxidant outlets which are disposed further on the outer side than the raw material powder outlets, and which spout a second oxidant; and a dispersal member which is provided in the raw material powder outlet, and which disperses the raw material powder by colliding with raw material powder that is supplied to the raw material powder outlet, wherein a shape of the raw material powder outlet is a ring form which is partitioned by a leading end of a first circular member and a leading end of a second circular member which is disposed on the outer side of the first circular member, and the dispersal member includes a first inclined surface that disperses the raw material powder in a direction that approaches a central axis of the combustion burner toward a leading end surface of the combustion burner, and a second inclined surface that disperses the raw material powder in a direction that becomes separated from the central axis of the combustion burner toward the leading end surface of the combustion burner.
