PURPOSE:To provide a gas mixer dispensing with a damper, constituted of such a mechanism that the interior of a cylindrical mixer is divided into an outer peripheral cooled gas distributing chamber and a central mixing chamber and heated gas is supplied to the mixing chamber while cooled gas is supplied to the cooled gas distributing chamber to be blown into the mixing chamber. CONSTITUTION:A cylindrical castor pull 14 is provided in a cylindrical mixer main body 13 and the interior of the main body 13 is divided into an outer peripheral cooled gas chamber 15 and a central mixing chamber 16. A heated gas supply port 19 for supplying heated gas (b) is provided to the mixing chamber 16 from the axial core direction of the main body 13 and a cooled gas supply port 17 for supplying cooled gas (a) is provided to the cooled gas distributing chamber 15 while a plurality of blow-in ports 18 for blowing cooled gas (a) in the cooled gas distributing chamber 15 into the mixing chamber from the direction at right angles to the axial core direction of the main body 13 are provided to the castor pull 14 in the peripheral direction thereof. The gaseous mixture (c) mixed in the mixing chamber 16 is taken out from a gaseous mixture takeout port 20. |
