ARTHUR EDWIN LEIGH SCANES, OF ASHTON-ON-MERSEY, ENGLAND, ASSIG'NO'IR. TO WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA- CONDENSER.

Specification of Letters Patent.

Application filed April 10, 1920. Serial No. 372,942.

To all whom it may concern:

Be it known that I, ARTHUR EDWIN LEIGH SoANEs, a subject of the King of Great Britain, and a resident of Strathfield, Harboro cooling water circulates. The invention has particular reference to the location andarrangement of the tubes'withinthe condenser.

Theobject of the invention is to reduce the pressure drop of the steam passing through the condenser due to the friction of the steam passing over the condenser tubes.

The accompanying drawing is a cross sectional view of'a surface condenser with its tubes arranged in accordance with the present invention.

The condenser shell is indicated in dot and dash lines at 1 with a steam inlet 2 at the top and an air outlet 3 with the usual bafile plates near thereto. tudinal stay is shown at 5. As will be seen from an inspection of the drawing, the arrangement of the tubes 6 is such that the steam entering the inlet 2 will flow downward between the tubes in substantially straight linesin the upper part of the nest of tubes both from the top and at the sldes parallel with the direction of the flow at the'inlet until it reaches the center portlon of the tube nest when the remaining uncondensed steam will follow irregular paths be-.

tween the remaining tubes in the lower part of the condenser toward the air outlet'3.

In condensers of large size it is very desirable to reduce the loss of head through the condenser to a minimum and according to the invention this is accomplished by arranging the tubes so that at the inlet and at thesides of the condenser the parallel lines are substantially parallel with the flow of V steam at the inlet, while in the center of the through which the The usual 'longicondenser and near the air outlet, the parallel lines lie in a direction substantially perpendicular thereto. Preferably the surfaces of intersection of the two arrangements of tubing are planes, which facilitates manufacture.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited but is susceptible' of various other changes and modifications without departing from the spirit thereof and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specificall What claim is:

1. A condenser of the surface type having inlet means, outlet means and water tubes, a group of said tubes being arranged in lines parallel to the flow of steam through the inlet and at the sides thereof and other group or groups'of tubes arranged in parallel lines perpendicularto the lines of the first group.

Patented June 28, 1921.

set forth in the appended claims.

2. A condenser provided with a steam inlet 2' and an air outlet, a group of tubes arranged in lines parallel to the flow of steam through said inlet and at the sides thereof, and other tubes within said condenser arranged in lines perpendicular to the lines of the first group and between the first group and the air outlet.

3. A condenser having a steam inlet, an airroutlet and a baffle plate contiguous to said air outlet, a group of cooling tubes wlthin the condenser arranged in llIlBS parallel to 1 the direction of flow of steam through the inlet and a second group of cooling tubes arranged in lines perpendicular to the lines of the first group and being overlapped at the ends by tubes of the first P in lines parallel to those of the second group and located between the first two groups and said baffle plate.

In testimony whereof, I have hereunto subscribed my name this twelfth day of March, 1920.

ARTHUR EDWIN LEIGH SCANES.
