In this paper has been presented a methodology of validation a novel mathematical model dedicated to evaluation and prediction of material degradation and damage of steam turbine elements such as blades, valves, and pipes due to three mechanisms: stress-corrosion, high-temperature creep and low-cyclic fatigue. The validation concept is based on an experimental setup manufactured in the Laboratory...
A Baumann stage is one of the way, to increase the turbine’s output without an increase of the last stage blade length. Due to the complicated design, the Baumann’s blade technology is complex, and its efficiency is lower in comparison to a free-standing blade. Currently that stage is used mostly in back pressure cogeneration heating turbines. This paper presents the operation of low pressure part...
