Abstract
A double flow-type steam turbine installation in which two turbine sections of a double flow-type steam turbine are provided with different final stage steam path areas. The turbine section with the higher area is connected to a high vacuum condenser while the turbine section with the lower area is connected to a low vacuum condenser. The cooling water systems of the two condensers are connected in series with each other. The efficiency of the system is significantly increased over previous installations.
Claims6
A double flow-type condensing turbine installation comprising:
- a double flow-type steam turbine having first and second turbine sections, said first turbine section having a larger final stage steam path area than said second turbine section;
- a high vacuum condenser having a cooling water system, said first turbine section being coupled to said high vacuum condensor;
- a low vacuum condenser having a cooling water system, said second turbine section being coupled to said low vacuum condensor;
- and
- said cooling water systems of said high and low vacuum condensers being coupled in series with one another.
A multi flow-type condensing turbine installation comprising:
- at least first and second double flow-type steam turbines, said first turbine having a larger final stage steam path area than said second turbine,
- a high vacuum condenser having a cooling water system, said first turbine being coupled to said high vacuum condenser;
- a low vacuum condenser having a cooling water system, said second turbine being coupled to said low vacuum condenser;
- and
- said cooling water systems of said high and low vacuum condensers being coupled in series with one another.
