Abstract
Abstract A protective device for the condenser tubes of a steam surface condenser. A baffle arrangement prevents direct impingement of high velocity against the tube bundles closest to the condenser inlet. Legs extend from the baffle between the individual tubes of the tube bundles to substantially dampen vibrations of the tubes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
In combination, a condenser having an inlet for steam to be condensed, a plurality of spaced-apart tube bundles each including a plurality of individual tubes for carrying cooling fluid, and apparatus for preventing direct impingement of highvelocity steam against and dampening vibration of the individual tubes which form the tube bundles closest to said inlet comprising: a plurality of spaced-apart baffle means positioned between the condenser inlet and the tube bundles for directing the major portion of steam between said tube bundles; and means secured to said baffle means and extending into said tube bundles for dampening vibrations of the individual tubes which form said tube bundles; wherein: said means for dampening vibrations includes both tube support plates and a pair of fingers, each of said fingers extending between said individual tubes and wherein at least some of said individual tubes are held by said fingers.
Claim 2
Dependent Claim
146 words
In combination, a condenser having an inlet for steam to be condensed, a plurality of spaced-apart tube bundles each including a plurality of individual tubes for carrying cooling fluid, and apparatus for preventing direct impingement of highvelocity steam against and dampening vibration of the individual tubes which form the tube bundles closest to said inlet comprising: a plurality of spaced-apart baffle means positioned between the condenser inlet and the tube bundles for directing the major portion of steam between said tube bundles; and means secured to said baffle means and extending into said tube bundles for dampening vibrations of the individual tubes which form said tube bundles; wherein: said means for dampening vibrations includes both tube support plates and a pair of fingers, each of said fingers extending between said individual tubes and wherein at least some of said individual tubes are held by said fingers.
Claim 3
Dependent Claim
22 words
The combination of claim 1 wherein said fingers are spaced apart a distance equal to the outside diameter of said individual tubes.
Claim 4
Dependent Claim
30 words
The combination of claim 1 wherein each of said baffle means overlies one of said tube bundles and has a width substantially equal to the width of said tube bundles.
Claim 5
Dependent Claim
22 words
The combination of claim 3 wherein said baffle means is triangular in configuration having its apex facing the inlet of the condenser.
Claim 6
Dependent Claim
35 words
The combination of claim 4 wherein said means for dampening vibrations includes a pair of fingers each extending between said individual tubes and at least some of said individual tubes are held by said fingers.
Claim 7
Dependent Claim
129 words
In combination, a condenser having an inlet for steam to be condensed, a plurality of spaced-apart tube bundles each including a plurality of individual tubes for carrying cooling fluid, means for supporting said tube bundles, and apparatus for preventing direct impingement of high-velocity steam against and dampening vibrations of the individual tubes which form the tube bundles closest to said inlet comprising: a plurality of spaced-apart baffle means positioned between said inlet and the tube bundles for directing the major portion of steam between said tube bundles; and at least a pair of spaced-apart finger means secured to said baffle means and extending toward said tube bundles for dampening vibrations of the individual tubes which form said tube bundles; wherein: said baffle means is mounted on said supporting means.
Claim 8
Dependent Claim
129 words
In combination, a condenser having an inlet for steam to be condensed, a plurality of spaced-apart tube bundles each including a plurality of individual tubes for carrying cooling fluid, means for supporting said tube bundles, and apparatus for preventing direct impingement of high-velocity steam against and dampening vibrations of the individual tubes which form the tube bundles closest to said inlet comprising: a plurality of spaced-apart baffle means positioned between said inlet and the tube bundles for directing the major portion of steam between said tube bundles; and at least a pair of spaced-apart finger means secured to said baffle means and extending toward said tube bundles for dampening vibrations of the individual tubes which form said tube bundles; wherein: said baffle means is mounted on said supporting means.
Claim 9
Dependent Claim
31 words
The combination of claim 6 wherein each of said finger means includes a pair of substantially rigid fingers extending from said baffle means between the individual tubes of said tube bundles.
Claim 10
Dependent Claim
36 words
The combination of claim 7 wherein each of said baffle means is triangular in configuration and overlies one of said tube bundles and has a base dimension substantially equal to the width of said tube bundles.
Claim 11
Dependent Claim
25 words
The combination of claim 8 wherein the fingers of said finger means are spaced apart a distance equal to the outside diameter of said tubes.
