Abstract
A condenser system for steam turbine systems having different loads is disclosed. The condenser system includes a selectively sized outer casing having a variably sized heat exchanger end and an input end for coupling to a steam turbine (ST) system. A condensate vessel sidewall of the casing is positionally uniform relative to the ends regardless of the size of the heat exchanger, and a cooling water sidewall has a position dependent on heat exchanger size.
Claims18
A condensate vessel assembly for a condenser system of a power plant, the assembly comprising:
- a first support structure freestanding from the condenser system;
- a first condensate vessel positioned on the first support structure, the first condensate vessel configured to receive steam condensate from a plurality of drain pipes of a steam turbine system;
- a second condensate vessel positioned on the first support structure, the second condensate vessel configured to receive steam condensate from a plurality of condensate pipes of a water steam cycle system for the steam turbine system;
- a first plurality of intake lines mounted on the first support structure, each first intake line configured to fluidly connect to a respective one of the plurality of drain pipes to the first condensate vessel;
- and
- a second plurality of intake lines mounted on the first support structure, each second intake line configured to fluidly connect to a respective one of the plurality of condensate pipes to the second condensate vessel.
