generated in the flowing gaseous mixture as it travels through an arc to opening 11 would ordinarilyseparate the heavier particles of liquid still remaining therein from the remainder of the mixture and cause it to collect along the outer curved Wall 15. I obviate this difficulty by dividing the mixture up into four small streams, thereby accelerating its speed of movement and securing complete, positive and final vaporization of all the heavier particles still remaining in the mixturethroughcontact with the heated Webs. I i 7 It may now be readily seen from the foregoing disclosure that have provided a structure in Which'the exhaust and the fresh mixture are moved in opposite directions to each other and inheat exchanging relationship to each'other in such a manner that a combustible mixture passed through the manifold is discharged therefrom'in perfect condition for use.
