Answer Posted / sanjay singh kharola
the mass of casing is more than mass of rotor so the casing
heated slowly than rotor and also it cools slower than rotor
hence during the starting of turbine when preheating is
carried out (preheating done to reduce the thermal stress)
the rotor expansion is faster than casing expansion this is
call "rotor long", similarly when the turbine is triped (
that is when steam supply is shut off) the rotor cool
faster than casing and this is called "rotor short"
