Abstract
A start-up system mixing element including; a body defining a cavity, a first inlet port disposed in the body and configured to provide a first fluid to the cavity, a second inlet port disposed in the body and configured to provide a second fluid to the cavity, an outlet port disposed in the body and configured to remove the first and second fluids from the cavity and an internal distribution pipe disposed in the first inlet port, wherein the internal distribution pipe is configured to provide the first fluid to the cavity via a plurality of holes directed toward a center of the cavity.
Claims19
A start-up system mixing element comprising:
- a body defining a cavity;
- a first inlet port disposed in the body and configured to provide a first fluid to the cavity;
- a second inlet port disposed in the body and configured to provide a second fluid to the cavity;
- an outlet port disposed in the body and configured to remove the first and second fluids from the cavity;
- and
- an internal distribution pipe disposed in the first inlet port, wherein the internal distribution pipe is configured to provide the first fluid to the cavity via a plurality of holes directed toward a center of the cavity.
A power plant comprising:
- a main feed-water line;
- a main bypass line connected to the main feed-water line;
- an economizer feed-water line connected to the main feed-water line;
- an economizer connected to the economizer feed-water line;
- a plurality of waterwalls connected to the economizer;
- a separator connected to the waterwalls and configured to separate liquids from steam;
- a recirculation water line configured to receive liquids from the separator;
- a start-up system mixing element connected to the main bypass line and the recirculation water line;
- a mixed feed-water line connected to the start-up system mixing element and the economizer feed-water line;
- and
- a circulation pump disposed along the mixed feed-water line between the start-up system mixing element and the economizer feed-water line,
- wherein the start-up system mixing element comprises:
- a body defining a cavity;
- a first inlet port disposed in the body and configured to receive a first fluid from the main bypass line and provide the first fluid to the cavity;
- a second inlet port disposed in the body and configured to receive a second fluid from the recirculation water line and provide the second fluid to the cavity;
- an outlet port disposed in the body and configured to remove the first and second fluids from the cavity;
- an access port disposed in the body and configured to provide manway access to the cavity;
- and
- an internal distribution pipe disposed in the first inlet port, wherein the internal distribution pipe is configured to provide the first fluid to the cavity via a plurality of holes directed toward a center of the cavity.
A method for mixing and filtering two fluids, the method comprising:
- providing a body defining a cavity;
- providing a first fluid to the cavity via a first inlet port disposed in the body;
- providing a second fluid to the cavity via a second inlet port disposed in the body;
- and
- mixing the first and second fluids in the center of the cavity before the fluids contact the body.
