PROTECTIVE METHOD OF EXTRACTION TURBINE PLANT Russian patent published in 2011 - IPC F01K17/00 

FIELD: power industry.

SUBSTANCE: protective method of extraction turbine plant against non-allowable pressure in condenser and temperature of exhaust pipe of turbine involves condenser with water circuit for heat supply system with stand-by pumps and the main circulation water circuit; at that, water temperature for heat supply system is provided, as well as water flow of heat supply system is increased by activating stand-by pumps at simultaneous achievement of maximum allowable pressure value in condenser and water temperature for heat supply system by supply and increase of water flow through the main circulation water circuit after repeated delay of the specified time interval at maintaining maximum allowable values of these parameters; at that, temperature of exhaust pipe of turbine is controlled by spray of desalinated water to cooling device located in the condenser neck by activating the appropriate number of atomisers at constant steam flow through some amount of low pressure of turbine.

EFFECT: high economy of extraction turbine plant at temperature control of exhaust pipe.
