Antivibration spacer tube

摘要

Vibration of boiler tubes in a bank of parallel tubes of a multidrum boiler is prevented by means of directing a restraining tube in each bank of tubes obliquely between spaced drums. The oblique tube is welded to the parallel tubes at each point of contact to provide mutual support therefor. Boiling water is directed through the oblique tube as well as the parallel tubes so that circulation through the tubes is enhanced while tube vibration is prevented.
