Effect of number of turbine impellers on surface aeration in laboratory fermentor

Biotechnology and Bioengineering, 1989
AbstractThe effect of one and two four‐flat‐bladed turbine impellers on the surface aeration intensity in a laboratory tormentor was investigated at different agitation speeds and sparge rates. The surface aeration was found to be generally more intensive with two impellers for the same other operating conditions because of higher power consumption and

Fatigue Failure of an Aluminum Turbine Impeller

1993
Abstract An AMS 4126 (7075-T6) aluminum alloy impeller from a radial inflow turbine fractured during commissioning. Initial examination showed that two adjacent vanes had fractured through airfoils in the vicinity of the vane leading edges, and one vane fractured through an airfoil near the hub in the vicinity of the vane trailing edge ...

Metallurgical Failure Analysis of Cracks in a Compressor Turbine Impeller

1993
Abstract Cracking was discovered in an in-service, second-stage turbine impeller during a downtime inspection. The fabricated 4300 series low-alloy steel impeller was used in a compressor in an industrial petrochemical plant. It was also reported that a process upset had allowed a 10% NaOH solution to be ingested by the unit.
