ABSTRACT:
An arrangement for introducing air into the draft tube of turbo-hydraulic machines, in order to promote smooth running at part-load and to facilitate the achievement of full load, relies upon the use of a protective plate in covering relation with the air admission opening and cooperating with the structure located within the draft tube to act as an air eductor, in the manner of a venturi.
