Abstract
The invention relates to a turbine ( ) having a rotor ( ), which has a bladed area ( ) for rotor blades ( ) and a thrust compensation piston ( ). The thrust compensation piston ( ) has a hot side ( ), which faces the bladed area ( ), and a cold side ( ), which is remote from the bladed area ( ). On one side, a feed ( ) for sealing fluid ( ), which is assigned to the cold side ( ), and a leakage fluid feed ( ), which is flow-connected to the bladed area ( ), open out into a mixing area ( ), and on the other side a discharge line ( ) branches off from the mixing area. The invention also relates to a method for discharging hot leakage fluid ( ). In a turbine ( ), the leakage fluid ( ) passes through a radial gap ( ) between a thrust compensation piston ( ) of a rotor ( ) and a stationary turbine part ( ) and is mixed with a cooler sealing fluid ( ) and discharged.
