Answer Posted / devanesan
By maintaining vacuume in turbine the efficiency of the
turbine will increase by making making maximum heat utilization
also reduce external stress in the rotor by free steam flow to
the condenser.
(for example without vacuum the barring gear speed
will less than the without vacuum speed. due to the
atmosphere pressure some external stress acting on the
rotor.)
