The results showed that desulphurization rate was apparently influenced by lance level while it was not obviously influenced by inclination of lance and bellmouth height; desulphurization rate was becoming slow if carrier gas flow was too low (Q=25Nm~3/h) and was not obviously influenced if carrier gas flow was over some value.

载气流量过小时(如Q=25Nm~3／h)会明显降低镁脱硫速率，载气流量增大到一定值后、再继续增大时对脱硫速率不会产生明显影响。喷枪夹角和喷枪喇叭口高度的改变对脱硫速率没有明显影响。
