Definitions
- the battle arrangement deflects incoming steam so that it flows between the tube bundles and thereby insures that there is no direct impingement of high velocity steam on the top of the tube bundles.
- the arrangement is designed to minimize pressure losses so that it may be placed over the entire inlet of the condenser or only in those regions where the steam is entering at maximum velocity.
- This invention relates to steam surface condensers and in particular to condenser tube protective devices for use with such condensers.
- the invention provides apparatus for preventing direct impingement of entrained high velocity water droplets on condenser tubes.
- baffles, screens, and other apparatus have been inserted between the inlet of the condenser and the tube bundles. Such apparatus was designed to prevent direct impingement of moisture droplets on the tube bundles. Such prior apparatus, however, caused high pressure losses resulting in poor condenser performance.
- a second approach is to use harder tube material to reduce failure due to erosion. This, however, does not overcome the problem as even the harder material is subject to eventual failure. In addition, the harder material is costly resulting in a greater initial cost of the condenser.
- a condenser having an inlet for steam to be condensed, a plurality of spaced apart tube bundles for carrying cooling fluid and apparatus for preventing direct impingement of high velocity steam against the tube bundles closest to the inlet comprising: a plurality of spaced apart first baflle means positioned between said inlet and said tube bundles; a plurality of spaced apart second baffle means positioned between said first baflle means; said first and second baffle means being positioned with respect to each other and to said tube bundles for directing the major portion of steam to be condensed between said tube bundles.
- FIG. 1 is a top plain view of a condenser employing one embodiment of this invention
- FIG. 2 is a view showing an impingement protecting device in accordance with this invention.
- FIG. 3 is a perspective view of the impingement protecting device of this invention.
- a condenser generally indicated at 1.
- This condenser includes a shell having walls 2 and an inlet 3.
- the condenser 1 may be provided with the usual feed water heater 4.
- a plurality of spaced apart tube bundles generally indicated at 5 are mounted within the condenser.
- Each of the tube bundles 5 is made up of a plurality of tubes 6 which carry a cooling fluid such as water for condensing steam.
- the area of maximum velocity incoming steam is indicated in broken lines as at 7. This area will depend upon the conditions of service and the type of turbine actually used.
- An impingement protecting device generally indicated at 10 and best shown in FIGS. 2 and 3 is preferably placed in each area 7 of maximum velocity incoming steam.
- the impingement rack 10 is mounted on support plates 11 which may also be used to support tube bundles 5.
- Support plates 12 are mounted on plates 11 in any suitable manner such as by welding.
- First baflie .means 15 comprising a plurality of spaced apart large diameter pipes extend between the plates 12 and are located between the inlet and the tube bundles 5.
- the longitudinal axis of the pipes 15 is parallel to the longitudinal axis of the tube bundles 5.
- Each pipe 15 is preferably of a diameter large enough to substantially cover the width of the tube bundle below it.
- the pipes 15 are spaced apart a distance approximately equal to the distance between the tube bundles 5. If desired, some means other than pipes may be used although a convex surface facing the inlet is preferred since this aids in reducing pressure losses.
- a second baflle means generally is indicated at 16 is placed between the inlet and the first baflle means 15 and is also positioned between the spaced apart pipes 15.
- This second baffle means 16 includes pipes 17 extending between plates 12 and plates 18 secured to the pipes 17 extending downwwardly therefrom.
- the longitudinal axis of the plates 18 is parallel to the longitudinal axis of the pipes 15.
- the pipes 17 may be replaced by some means having a convex surface facing the inlet of the condenser.
- Tube bundles lower than those shown in FIG. 2 may be positioned in the path 21 but by the time the steam reaches these tube bundles suflicient condensing will have taken place so that the velocity will have de creased sufficiently so that erosion damage will be almost eliminated from the direct impingement of the moisture droplets on these tube bundles.
- round pipes 15 and 17 insures proper flow of steam and insures that pressure losses normally associated with prior baffie arrangements are substantially reduced.
- the tube bundle protecting rack is preferably placed in areas where there is a highest velocity incoming steam, the pressure losses are so slight that the rack may be placed throughout the inlet of the condenser.
- a condenser having an inlet for steam to be condensed, a plurality of spaced apart tube bundles for carrying cooling fluid and apparatus for preventing direct impingement of high velocity steam against the tube bundles closest to said inlet comprising:
- said first and second baffie means being positioned with respect to each other and to said tube bundles for directing the major portiOn of steam to be condensed between said tube bundles.
- a condenser having an inlet for steam to be condensed, a plurality of spaced apart tube bundles for carrying fluid and means for preventing direct impingement of high velocity steam against the tube bundles closest to said inlet comprising:
- first bafiie means mounted in said condenser and positioned between the inlet and the tube bundles;
- each of said first baffle means overlying one of said tube bundles
- bafile means mounted in said condenser and positioned between said inlet and said first bafiie means.
- each of said first baffle means has a convex surface facing said inlet and a width substantially equal to the width of said tube bundles.
- each of said second bafile means includes a first member having a convex surface facing said inlet and a plate member extending downwardly from said first member between a pair of said first bafile means.
