Of steam seal on a steam turbine temperature in incorrect could cause damage. This could cause it not to work right.
For efficiency's sake, the outlet had best be a lot cooler.
In a back pressure turbine all available energy from the inlet steam is NOT used to generate power; steam exhausts at a tangible pressure and is then used for, usually, heating or chemical processing. In a condensing turbine, all the inlet steam does mechanical work right down to the lowest pressureafter which it is condensed in a heat exchanger
exhaut steam temperature raising due to cooling water inlet temperature raise vacuum pullying is not proper scale formation in turbine blades
The boiler heats water into steam. The steam is pressurized and fed into a turbine which causes it to rotate. As the steam turbine rotates, the connected generator rotates and produces electricity. Make Sense??? Please 'Recommend Contributor'

when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
The purpose of exhaust hood spray is to decrease the temperature of steam turbine last stage that is probably LP. This is operate on low load specially at start up and shut down of steam turbine when the temperature at the outer most edge of the turbine blades of that stage is very high and As we know that the steam flow also decrease The temperature of turbine blade.

flood the condenser and rip the fix and moving blades though the casing, also causing loss of vacume
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
as the air passes through adiabatic compression volume shrinks and hence temperature rises
Thrust bearings are mounted on turbines at or near the end of the shaft, closest to the steam chest (or inlet). This is to maintain the shaft in position with the casing of the turbine, allowing the casing and the shaft to expand evenly together toward the drive end of the turbine.
