The steam turbine is mainly composed of condenser, circulating pumps, air extractor and condensation water pump etc.
The steam after working in the turbine enters to the condenser and is cooled by the cooling water input from the circulating water pump into condensate water, and then is pumped by the condensation water to the gland heater to absorb the heat discharged from the gland steam, at last it is sent to the low-pressure heater. In order to avoid the air leaking in the condenser not to accumulate more and more and reduce the vacuum, the steam-jet ejector is provided in the system to exhaust the air inside the condenser and to maintain the vacuum in the condenser. The gland leakage steam is condensed into water and sent to the condenser.
