The utility model relates to a gaseous air duct for provide gaseous for brilliant boat in the boiler tube, gaseous air duct includes the body, the body has relative inlet end and end, on the pipe wall of body along the inlet end extremely the air vent that link up is seted up to the end, interval between the air vent is followed the inlet end extremely the end reduces gradually. The air vent that reduces gradually to terminal interval from the inlet end is seted up at the pipe wall of breather pipe body to the adoption, and the concentration of the gas realizing coming out from the air vent is the same, and then makes the nature and the thickness homogeneous of the membrane that the wafer formed on the brilliant boat send, has solved among the prior art because between the wafer that the gas strength difference leads to diffusion or the thick inconsistent problem of deposited film. 本实用新型涉及一种气体导气管，用于炉管中为晶舟提供气体，所述气体导气管包括管体，所述管体具有相对的进气端和末端，所述管体的管壁上沿着所述进气端至所述末端开设有贯通的通气孔，所述通气孔间的间距从所述进气端至所述末端逐渐减小。采用在通气管管体的管壁开设从进气端至
