CONDENSER Filed May 13. 1929 o o o o o o o o o o o oooooeoooao ooooaooooa oooaoo 1 INVENTOR. Tau ZI-Bmmtel HLSATTORNEY Patented Nov. 8, 1932 UNITED STATES PATENT OFFICE ASSIGNOR T INGERSOLIi-RAND GOM- CORPORATION OF NEW JERSEY CONDENSER Application filed May 18,
This invention relates to condensers, but more particularly to surface condensers in which tubes are arranged in a group or groups and transversely of the steam flow so that the steam intended to be condensed will come into direct contactwith the surfaces of the tubes.
One object of the invention is to restore to the condensate a portion of the heat lost during the process of condensation of the steam,
and another object is to reduce the volume of the air and uncondensible gases by bringing these elements into intimate contact with the condensate in a region in a condenser in which the condensate has reached its lowest tem- 10 perature.
Other objects will be in part obvious and in part pointed out hereinafter.
The figure in the drawing is a transverse sectional elevation of a condenser construct ed in accordance with the practice of the invention.
Referring more particularly to the drawing, A designates a condenser comprising a casin B at the top of which is an inlet opening 5 through which the steam intended to be condensed may enter the casing B.
The condenser A is provided with water conveying tubes D arranged transversely of the steam flow and in a plurality of groups, in this instance two groups E and F. In the arrangement shown the group E is disposed near the inlet opening G and the group F beneath the group E and spaced therefrom to form a steam lane G through which steam may flow to the group F.
In order to assure an adequate distribution of steam to the several groups, the casing B is provided with inner walls H which preferably lie closely to the sides of the group E and are spaced from the wall of the casing B to form passages J through which steam may be bypassed from a point above the group of tubes E to the steam lane G. i
In accordance with the present invention, means are provided for re-heating the condensate immediately prior to its issuance from the condenser through an outlet opening K which may be in communication with suitable pumping apparatus (not shown) for removing the condensate from the condenser.
1929. Serial No. 364,193.
The means provided for this purpose comprises a wall L which may lie directly beneath the tube group F and is provided with a series of perforations O to divide the condensate into a plurality of streams during its course rom the condensing com artment P intov a condensate compartment 5 adjacent the outletopening K.
The wall L has an integral inclined or curved portion R which terminates at its uppermost end in substantially the same plane as the uppermost row of tubes of the group F and is connected at this end to the wall of the casing B by means of a lateral wall S which lies across the outlet opening of one of the passages J. V
In the wall S is an opening or openings T through which steam may enter the conduit U between the inclined portion R of the wall L and the wall of the casing. Such steam Fa flowing through the conduit U will pass into the condensate compartment Q where it will intermingle with the streams of condensate issuing from the perforations O and will be condensed thereby. In this way the heat of the steam will be transferred to the condensate and thus a portion of the heat lost by the condensate during the process of condensa tion will be regained prior to the delivery of the condensate to the boilers. 80
Preferably the condenser is provided with a separate outlet opening V for conveying air and uncondensible gases from the condenser. The outlet opening V in this instance is associated directly with the condensing compartment P and may be in communication with suitable evacuating apparatus (not shown), such as a steam jet or vacuum pump for evacuating the air and gases. In the pres-- ent instances such air and gases are directedto the outlet opening V by a battle W corresponding in curvature substantially to that of the adjacent portion of the casing B and a portion of the bafiie W overlies a portion of the wall L, thus forming a' restricted space 5 K through which the air and gases enter the outlet opening V. The free end or edge Y of the wall S preferably lies in the same transverse plane as the lowermost tubes of the group F so that the air and gases will be 100 densate issuing from the perforations the heat drawn through the condensate at a portion of the condensing compartment in which the condensate reaches its minimum temperature. Due to this arrangement the volume of air and gases will be greatly reduced prior to its evacuation from the condenser.
Inthc operation of the condenser, steam entering the inlet opening C will flow against -flow on the wall L and thence pass through the perforations 0 into the condensate compartment Q. The condensate is thus d1- vided into a plurality of separate streams "with air 7 spaces between them.
At the same time live steam will enter the conduit U through-the opening T and will be directed transversely of the direction. of flow of the condensate through the perforations 0. By its intimate contact with the conof the'stearn will be transferred to the condensate and in this .way increase the temperature thereof prior to itsremoval from the condensate compartment Q. The air and uncondensible gases of the stream utilized for reheating the condensate will "be drawn through the perforations O and will heremoved from the condenser together with the air and gases in the condensing compartment P.
