Abstract
A powder supply method for causing a powder supplied from a top end 70t of a tube 70 to flow down within the tube 70 and be discharged from a bottom end 70b of the tube, in which if M [kg/s] is a supply flow rate of the powder and AS [m2] is a cross-sectional area of the bottom end 70b of the tube 70, the following expression is satisfied. 1.5≤(M/AS)≤135
Claims8
A powder supply method comprising supplying a first powder from a top end of a tube;
