<p>The present invention provides an apparatus for producing powder. The apparatus can reduce running costs, prevents unidirectional flow of combustion exhaust gas flowing in a vertical channel, and can uniformly heats particles of the powder, flowing and moving up and down in a furnace. Raw material discharging nozzles (4a) constituting a first raw material discharging nozzle array (44) are arranged to have the same pitch angle. Other material discharging nozzles (4b) constituting a second raw material discharging nozzle array (46) are arranged to have a pitch angle smaller than that of the raw material discharging nozzle (4a). The first raw material discharging nozzle array (44) and the second raw material discharging nozzle array (46) are arranged to form a half pitch angle with respect to each other. Gaps between the nozzles are formed as a pathway for the combustion exhaust gas.</p> |
