FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 350,300, dated October 5, 1886.
Application filed February 1, 1884. Serial No. 119,535. (No model.)
ers, of which the following is a specification.
My invention relates to that class of apparatus in which heat or cold is to be transmitted to fluids by means of a heat-conductin g surface, which separates the fluid to be acted upon from a fluid which acts as the medium of heat or cold.
In such apparatus the heating or chilling fluid is often confined in concentric annular chambers closed by rings at both ends, these chambers being held in place by means of tubeplates, through which they each communicate, by means of suitable tubes, with a chamber connected wit-h the source of supply or exhaust, these tubeplates being bolted into and forming a part of the outside casing.
My invention consists, chiefly, in connecting a series of chambers closed at each end, as described, by means of an inlet-pipe at one end and an outlet-pipe at the other, both of suitable diameter, and lying entirely within the easing,and so attached to and supporting this series of chambers,without the addition of the tube-plate, that the series of chambers may be removed without taking the casing to pieces.
It also consists in certain details of construction below described. Such a heater is shown and described in Letters Patent No. 314,003, granted on my application March 17, 1885.
In the drawings is shown at Figure l a vertical section of a feed-water heater embodying my invention. Fig. 2 is a eross'seetion on line at as, Fig. l; and Fig. 3 shows a modification. Fig. 4 is a detail of chamber and ring, and Fig. 5 is a plan view of agitator.
A is the casing, provided with an inlet and outlet, a a, for water.
B is a series of chambers formed by the cylinders b,connected in pairs by rings 1), attached thereto in some suitable way,these rings forming the top and bottom of the chambers. Each of these rings isprovidcd with two couplingnecks, b
D D are cross-pipes, each provided with necks d, by means of which and the necks b" it may be connected with each of the chambers in the series B. The chambers B may be supported in the casing A by means of brackets e or in anyother suitable way.
F is an agitator of the shape shown. It 0011- 5 sists of a sleeve, having a number of crossarms, f, projecting from it, so that when rotated the water in the chamber surrounding the cylinders B will be kept in motion, and any impurities kept from settling, so that they will be drawn off with the feed-water which is being heated, and may be separated from such feed-water by afilter or other like means. Such an agitator is particularly necessary where the water contains a carbonate or sulphate'oflime,which is insoluble at a high temperature, and hence if drawn off with the water can be separated from it by a filter, and so damage neither the boiler nor the heater."
The sleeve f passes through astuffing-box, f
and is rotated about the outletpipe D by means of suitable gearing and shafting, f 3 f D is an inlet-pipe for the steam, connecting with the upper cross pipe, D. I
G an outlet-pipe for the purposes of allow-v ing steam and any gas thrown off by the water to escape. It is intended that the waterlevel in the heater should be below the mouth of the pipe. This pipe should be so carried out of the heater as to allow the easy removal of the nest of cylinders B.
A heater constructed as above described may be operated as follows: Steam is allowed to circulate through the chambers B, entering by means of the pipes D D, and passing out by means of the pipes D D '\Vater will be circulated in the chambers about the cylinder B, and any steam, &c., which may arise from the water may be conducted off by the pipeG or other opening, the circulation of the water being carried on by means of apump,orin any other suitable way. The agitator F breaks up the water and keeps it in motion, enabling it to circulate better, and preventing any solid particles from settling and forming a deposit on any portion of the heater.
The chief advantage of this construction is in the taking apart of the apparatus for cleaning. To do this the top of the casing A is first removed, the joint between D" and D being broken. Then the joint D D is broken and the nest B lifted out of the heater. The nest is one structure,which maybe tested forleaks very easily and simply without breaking a large number of joints. Moreover, in case any cylinder I) is injured, its place may be readily supplied without taking the whole structure to pieces.
In Fig. 3 a modification of my invention is shown, in which, instead ofconcentrie annular chambers, a set of four tubes, 11 H H 1-1", coiled concentrically,so as tolie one coil within another, as shown, are connected by the cross-pipe D at the bottom, and a mrresponding pipe at the top.
The pipe G can be used as well with other forms of heaters as with that shown in the drawings, its internal diameter depending in any ease upon the manner in which the heater is to be used, whether for making steam or otherwise.
Two or more series of chambers like those above described suitably connected may be used together within a large easing, if desired.
The apparatus above described is adapted for heating water; but it is obvious that with very slight ehangesit may be used equally well for condensing.
The cylinders I) are best made, as shown, of corrugated metal, in order to give a large heating-surface; but plain cylinders are also available. Their length should of course depend upon the height at which the water-line is expected to be maintained.
hat I claim as my invention is- 1. In a heater or like apparatus, a series of concentric annular chambers closed at each end by suitable rings and connected together at each end, and with a source of supply and exhaust by a cross-pipe, I) D, all as set forth.
2. In combination with an apparatus for heating water, consisting of a water-chamber provided with a suitable inlet and outlet, and suitable means of supplying heat to said water, a special educt connected with said water heating chambers above the water-line, as set forth.
3. In combination with an apparatus for heating water, consisting of a water-chamber provided with a suitable inlet and outlet, and the special eduet above the water-line, together with suitable means of supplying heat,
the agitator l hwhereby the mass of water may be broken and kept in a violent circulation,all as set forth.
4:. In an apparatus for heating water, provided with. a suitable inlet and outlet, and means fol-supplying heat, the combination of an agitator, whereby the mass of water may be broken up, and a special cduct above the water-line,whereby any steam or gas thrown oil" from the water may be conveyed away, all as set forth.
In. testimony whereof I have hereunto subscribed my name this li lth day of November, A. l). 1883.
