Erosion in the LP steam turbine last stage

thread281-438732

Erosion in the LP steam turbine last stage

Erosion in the LP steam turbine last stage

(OP)
It is observed after inspection of the LP steam turbine last stage which was running only couple weeks that the Erosion occurs in the trailing edge, do you have an explanations for this phenomena ?

RE: Erosion in the LP steam turbine last stage

Poor steam conditions causing water drop-out in the final stages of the machine. Check your condenser vacuum.

RE: Erosion in the LP steam turbine last stage

agreed....
verify exhaust cooling sprays are secured as soon as not needed
also extend operation at low load

RE: Erosion in the LP steam turbine last stage

Erosion damage to the trailing edge of last stage blades may also occur at low load due to recirculation of wet steam in the last stage. In these cases, the damage usually appears near the base of the last stage blades. When recirculation occurs, the only solution may be to operate at a higher load.

Best of luck!

the other question is related to the welding inspection does the PAUT replace the RT for welding inspection ?

Research Report - What’s the State of Nonlinear Simulation?
Simulation is an increasingly valuable tool across the product design workflow, but not all simulations are equal. We set out to determine how engineers and product designers make use of specialized analyses, how they incorporate nonlinear simulation into their work and how they rate the available software.

White Paper – Data Security and Know-How Protection
Our data is constantly exposed to the danger of being intercepted or stolen as it wends its way over global data networks. Data security measures and measures for protecting intellectual property should not, however, first be implemented when data is exchanged – companies must lay the foundation for these measures within their own organization.
