Unit after shutdown, as there is a temperature difference between the cylinder and the lower parts of the rotor may be resulting in bending, the bending degree with downtime increases, to a certain time to reach the maximum value; subsequently, with the cylinder on the lower part of the temperature difference between the reduced, rotor bend by gradually reduced. This phenomenon is called transient thermal bending of the rotor. When the bending of the rotor is still at large, it is not allowed to start the turbine. Therefore, in order to make the turbine can start at any time after the shutdown, it is necessary to use turning gear and drives the rotor for uninterrupted rotation, makes around a rotor temperature uniformity, in order to avoid the occurrence of the thermal bending phenomenon. Also, steam turbine before start, turn red, for turning gear for driven rotation of the rotor, to check and ensure that turbine dynamic and static parts without rub impact, guarantee the safe operation of the unit.
