Coherent jet lancing system for gas and powder delivery |
摘要 |
An arrangement wherein a coherent jet (62) is established proximate to a powder injection system and the coherent jet not only provides for gas delivery but also serves to improve the efficiency of the delivery of powder from the powder injection system. The arrangement provides in forming a flame envelope (63) around both the gas stream (62) and the powder mixture stream (67) delivered to a liquid, e.g. molten metal (65), from a gas jet nozzle (5,61) and a lance passage (66) for powder and carrier gas injection. <IMAGE> <IMAGE> |
