alcuen frasi:
No-load and low-load operation with low steam mass flow can result in an increase in temperature in the exhaust section of the LP turbine *through blade windage*.
The condensate injection equipment should then not be closed until the steam mass flow is sufficient *to prevent blade windage*.
A raised temperature in the HP exhaust due to insufficient flow *resulting in blade windage* can occur not only in no-load or low-load operation
During no-load operation and with low steam mass flow the temperature in the exhaust section of the LP turbine can rise *due to blade windage*.
*The windage in the blading* slows down the line of shafting and shortens the coastdown time.
The condenser low vacuum turbine trip also acts as an additional safeguard for *windage monitoring* and for protection of the LP turbine.

resistenza aerodinamica della pala

شرح:
windage = resistenza aerodinamica
www.menet.umn.edu/~marco/files/dizionario.pdf

windage - the retarding force of air friction on a moving object
drag, retarding force - the phenomenon of resistance to motion through a fluid

resistenza fluidodinamica incontrata /dalla pala/dalle pale/

The steam flow is insufficient to drive the turbine. Instead the turbine blades are driving the steam (or air/steam mixture) and heat is being created by the friction of the blades against the fluid.
