GOMIARTMENT SURFACE QONIFENSER.

To all whom it may concern:

Be it known that I, PAUL A. BANCEL, a citizen of the UnitedStates, and a resident of Nutley, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Compartment Surface Condensers, of which the following is a spec fication.

This invention relates to a compartment surface condenser and the primary object of the invention is to enable the different compartments to be readily cleaned as desired, while the condenser is in operation. Another object of the invention is to reduce the pumping power and cost in winter, by reducing the water quantity due to the fact that the water is colder and therefore less water is required.

To these and other ends hereinafter to appear, the-invention consists of the condenser shown in one of its preferred forms in the accompanying drawings, in which Figure 1 is a side elevation of a condenser embodying the invention,

Figure 2 is a transverse sectional elevation on the line 22 of Figure 1, taken through the inlet water box, looking in the direction of the arrows, and partly broken away,

. Figure 3 is a transverse sectional elevation on the line 3--3 of Figure 1, taken through the outlet water box, looking in the direction of the arrows, and partly broken away.

Referring to the drawings, the shell A of the condenser having suitable tubes and tube sheets is provided with the steam inlet B,

and the outlet connection C to which the cooler D is connected in this instance, 'having the water, inlet E, the water outlet F and the vacuum pump connection G.

The shell .A is provided with the inlet water box H at one end, to which the outlet Specification of Letters Patent. Patented Feb, 14, 1922 Application filed November 9, 1920. Serial No. 422,797.

sages S having the covers T so that communica-tion may be afforded between two of y the lower compartments.- Water inlet valves U and V control the supply of water to the water inlet box and discharge valves W and X control the discharge of water from the water outlet box. A main valve Y on the supply connection E of the cooler also discharge pipe 0 controls the discharge from the lower portion of said box. The compartments are provided with the remov-, able cover end.

In Isummer, or at such times when the full capacity of water inlet is utilized, the covers T on the partitions R are in position and each water box is divided in this instance into three compartments,'so that with all the valves open, the circulation of water is through the inlet valves U and V, the upper compartments: of the inlet box and :out through the discharge valves W and X. The circulation is also through the inlet valve Y, thence through the cooler and into the lower compartment of the inlet water box and out. through the discharge valve Z to the discharge pipe 0.

In the winter, by operating a large eondenser with most of the water forced through the valve U and the upper compart ments having the wide tube spacing, a high vacuum can be carried with small loss of pressure through the condenser and small reduc tion in temperature of the steam. This condition is effected. by throttling the inlet valves V and Y or else by closing the inlet valve V and removing the cover plates T on the partitions R, and throttling the inlet valve in which case the circulation is through the cooler- D and the discharge pipe J to the lower inlet compartment and through the passages S'in the partition R to the intermediate inlet compartment and thence to the final discharge through the valves X and Z, from the intermediate :and lower compartments of the outlet box. Under these conditions the greater portion of the steam will be condensed in the top of the condenser, so that the temperature of the bottom of the condenser will be near the temperature of the top. In the usual commer- 70, plates at, b ar d c as shown at each in the same way.

the valves are closed'except the inlet and cial'condenser the condensate may run 20 cooler in winter than the steam temperature and this means from 19 to 2% loss of coal in'the plant, or a loss the equivalent of onefoui' th inch in vacuum from the main turbine, and in accordance with my apparatus, 1 am enabled to save a substantial percentage of this loss.

Under winter conditions, or with light load, in case it is desired to run with less ,water and with normal vacuum, instead of eihg nsual amount of water and a higher vacuum, this-may be done, with the same valve setting above described andthe cover plates T removed.

' By closin -the inlet and discharge valves U and W, t e top compartment cover plates (1 may be removed and the tubes communieating with the uppercompartments cleaned while the condenser is still running with all other valves open. By closing the inlet and discharge valves V and X and leaving the other valves open, the intermediate cover lates b may be removed and the intermediate tubes cleaned. By closing the inlet and discharge valves Y and Z, the cover plates 0 for the lower compartment may be removed and the lower tubes cleaned.

B closing all valves except the inlet and discharge valves U and W, the water can be forced through the tubes communicating with the top compartments at very high velocity, thus cleaning said tubes, and by closing all the valves except the inlet and discharge valves V and X, the tubes of the intermediate compartments can be cleaned In the same manner if all discharge valves -Y and Z, the water can be forced through the tubes for the lower compartments at high velocity for cleaning said tubes and the ability to clean the tubes for any given compartment by forcing water at a high velocity through them, is another one of the advantages of my apparatus.

I claim:

1. Asurface condenser comprising a shell having tubes, water inlet and discharge boxes at each end of the shell divided into opposite compartments by horizontal partitions, the lower partition having passages and closing covers for said passages, sep arate removable covers for said compart- 'ments, an inlet pipe for the inlet box, a

discharge pipe for the discharge box, and inlet and discharge valves for each of said compartments.

2. A surface condenser comprising a shell having tubes, water inlet and discharge boxes at each end of the shell divided into opposite compartments by horizontal partitions, the lower partition having passages and closing covers for said passages, separate removable covers for said compartments, an inlet pipe for the inlet box, a discharge pipe for the discharge box, a

cooler connected to the condenser having an inlet for water and a vacuum pump connection, the water discharge of said cooler being connected to the lower compartment of the'inlet box, and inlet and discharge valves for each of said compartments.

In testimony whereof I have signed this specification.

PAUL A. BANCEL.
