JET-CONDENSER.

Patented Jan. 30, 1912. Serial No. 466259.

and useful Improvements in Jet-Condens ers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. This invention relates particularly to jet condensers of the so-called ejector type, the especial objects being to expose to the steam as large a surface of condensing water as possible, and to reduce the loss of energy or power required for water circulation.

In the accompanying drawings forming a part of this specification, there is shown a condenser of the preferred form einbodying the invention, and this construction will =3 now be described in detail and the features forming the invention then specifically pointed out in the claims.

In the drawings :F igure 1 is a vertical section of the condenser cone with the water and steam distributing devices in eleration. Fig. 2 is a vertical section on the line 2 of Fig. 4. Figs. 3 and 4 are sections on respectively the lines 3 and 4 of Fig. 2. Fig. 5 is a detail section of a portion of the water distributing ring, showing the adjustment for varying the condensing water. Fig. 6 is a view similar to Fig. 5 showing a modification. Fig. 7 is a section on the line? of Fig. 6.

Referring to said drawings, A is the condenser cone, B the discharge pipe to which may be attached a barometric tail pipe in a barometric condenser,C is the exhaust steam inlet, D the condensing water inlet, this condensing water inlet D being formed by a pipe extending downward centrally of the condenser. At the lower end of the water inlet pipe D is the casing E provided with passages for steam and water, and ring F forming an annular water chamber 12 surrounding the casing E and co-acting'with the bottom edge of the casing to form an annular water jet. The casing E is supported by a flange connection 10 with the lower end of pipe D and the ring is connected by bolted flange 11 with the casing E. .The lower edge 1 of ring F with the outer edge 2 of the bottom of .the casing E formsa narrow opening a, through which the annular water jet is thrown into the condensing chamber from the water chamber 12, this water chamber 12 being connected by water passages 13 with the pipe D, these passages 13 being arranged in an annular series about the casing E. Be-

tween the water passages 13 are the steam passages ll passing vertically through the casing E and connecting the steam inlet C with the condensing chamber inside of the annular water jet from passage a. Steam is also admitted to the condensing chamber outside of and surrounding the annular water jet through the narrow annular space or passage 15 surrounding the distributing apparatus between the ring F and the inner wall of the condenser cone.

The water thrown through the passage a forms complete cone having its apex in the narrow throat by which the condenser cone connects with the discharge pipe B, and preferably is out of contact with the inner wall of the condenser cone, as shown, so as to avoid the friction resulting from the water moving in contact with the wall at the high velocity required in these condensers. Loss of energy or waste of power of the circulating pump thus avoided. It will be seen," also, that, in the preferred construction shown, the water passes downward through the condenser without substantial change of direction which also avoids loss of energy and increases the efficiency of the condenser. The inside of this water cone is in contactwith the steam passing through openings 14 and the out side of the cone with steam passing through the annular passage 15, so that a single water jet provides two steam condensing surfaces, and secures a large condensing surface, and the steam is preferably distributed about equally on the two surfaces of the annular water jet, so as to secure the maximu'm condensing effect.

Theedges 1, 2 of the ring F and easing E are inclined so as to throw the annular jet inward in cone form, and for readily adjusting the amount of water passing through the condenser, the edges are so formed that the raising or lowering of the ring F decreases or increases the width of the passage a, as shown clearly in Fig. 5. The ring F may be adjusted by any suitable means, but as shown is adjusted by putting more or less packing 3 between the flange 11 and support oncasing'E to lower or raise the ring.

In some cases a. larger water surface than is obtainableby annular passage a may be desired, in which case notches b may be provided on one or both sides of the annular passage a, as shown in F igsf6 and 7,

- the adjustment of the width of the annular a water chamber,

passage (1 being still retained, if desired.

What is claimed is 1. In a water jet condenser, the combination with a condenser cone, of a vertical injection pipe in the upper part of the condenser and terminating in a casing separated from the condenser Wall and for 'ng nected with the water chamber through which an annular water et 1s thrown. downward m the condenser c0ne,'a steam inlet .abox e the casing, opening into the space an annular passage con-- casing and condenser 'wall, and passages through the casing for theadmission of steam from said steam inlet to the space within the annular water jet.
