Application led January 10, 1919. Serial No. 270,499.

To all Lo/tom t may 'concern Be it known that I, JOHN L. HUGHES, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of y Oklahoma, have invented certain new and of a steam boiler and other deposits therein p will be intimately commingled with theV water fedto the boiler prior to its entrance into the boiler'. The invention also seeks to provide means whereby the flow of the water and of the cleaning compo-und may be regulated and it also seeks to provide an apparatus for the stated purposes which will be simple in its. construction and arrange ment and may be installed in any boiler plant at a low cost.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a steam boiler and furnace having my improvements connected therewith;

Fig. 2 is an enlarged vertical section of the tank for containing the compound;

Fig. 3 is a detail view illustrating a slight modification.

The boiler 1 and the furnace 2 may be of any well-known construction, a steam chest 3 being provided upon the boiler' and equipped with a safety valve 4 and a cut-off valve 5 in the usual 'mannen The water for feeding the boiler is drawn through a supply pipe 6 `from any convenient source of supply and is delivered by said pipe into a heater 7 from which it is drawn by a pump 8 through the pipe 9 and then forced through a pipe 10 to the boiler. A. blow-ofi` l pipe 11 is provided to permit sediment and other matter to be blown from the boiler at intervals or whenever it is desired to shut down the'plant. The steam generated in the boiler is carried through a pipe 12 to the engine or other point of use and a branch 13 leads from the said pipe. From the branch 13 a second branch 14 leads to the pump so as to supply the steam necessary to operate the same and a cut-off valve 15 is provided in the said branch 14 to control the flow of steam therethrough. A third it@ leads from the main` steam branch pipe 13 into the heater 7 and may discharge freely into the same or may terminate in a coil as preferred. The steam admitted into the heater will raise the temperature of the water therein whether it cominingles; directly with the water or is merely' circulated through a heated coil and the condensed steam may be drawn off through the pipe 9 with the feed water. The pipe 13 continues past the Abranch 16 and has its end carried into the tank 17 containing the cleaning compound Vand within the tank commingles directly with a coil 18, as shown clearly in Fig. 2. A cut-off valve 19 is provided in the steam pipe 13 below the branch 16 and a cut-off valve 2O is provided in the said branch 16 so as to provide for thorough control of the flow of steam. The coil 18 leads into an outlet pipe 21 which may be carried to any desired point but will preferably be led into the heater 7 so as to` discharge the steam into the same and thereby aid in raising the temperature of the feed water.

While comparatively few plants at. the present time feed water into the boilers without previously heating same, there are plants in which the feed water is not heated. To permit the application of my apparatus to such plants the outlet pipe 21 may be carried downwardly, as shown at 28 in Fig. 3, so `as to communicate directly with the pipe 24 constituting the inlet pipe for the pump., the feed water pipe 25 communicating with the down-turned portion 23, as shown in said Fig. 3. Y will, consequently, act directly upon the feed water within a small compass so as to be thoroughly commingled therewith and will consequently serve to raise the temperature of the same before it enters the boiler.

The tank 17 may be constructed of any desired material and may be of any preferred capacity. From the lower end of the same an outlet pipe 26 leads to the pipe 9 and this outlet pipe is controlled by a cutolf valve 27 as will be readily understood, a tube 28 of transparent material being interposed between the valve and the pipe 9 so that the ow to said pipe will be visible and the volume of the cleansing fluid passing to the feed water may be known. The cleaning compound is deposited in a hopper 29 which is disposed above the tank and communicates with the upper end of the same through a spent er tube 30 in which is disposed a com trolling valve 3l. A vent 32 is provided at the top of the tank so that, when the tank is beingffilled, tthe trapped air may be permittedfto escape and undesirable accelerated feeding of the compound to the feed water will be avoided. A gage tube 33 is provided on the side of the tank so that the height of theliquid therein may be known and a clean out manhole 34 is also provided near the lower end of the tank. It sometimes happens that the tank must` be. located below the level of the waterin the heater or the level of the fluid in the tanks gets lower than valve 36be opened, steam will be admitted to .the tank abovethe level of the liquid .therein and will kexert l suliicient pressure upon the liquid to accelerate thelow ofV the same and obtain the desired results.

Itis thought theoperation oftheapparatus is evident 4from what has been said.

f The composition or cleaningfluid is fed into the tank from the hopper thereon .and the valve 27 is set to .permitescapeof thefluid y.from :the .tank at thedesired speed. The

apparatus will raise the temperature of the feed water suiiiciently to accelerate the formation of steamfand vconsequently effect an economy of fuel. The apparatus `does not occupy a large space and may beLreardily installedin plants now in use. The tank may be placed at any point on the water line between the source of water supply andthe boiler, thesteam pressure being suiiicient to inject the compound into the feed water and effect the commingling of the same.

.Having thusdescribed the invention, what is claimed as new is: i

1. In an 1 apparatus fonthe purposefset forth,y the combination of a feed Water supply pipe, a .container for avtcleaning compound in communicationwith said pipe, and a steam pipe in communication withfthe feed watersupply and having aportion of its length disposed withinthesaid container.

2. In an apparatus for. the purpose vset forth, the combination of a feed water supply pipe, a steam pipe, a tank to contain a cleaning compound, a coil within the ytank connected with the steam pipe, and means whereby steam from saidpipe. may becaused to act on the feed water.

3. In an apparatus ifor the purpose yset forth, the combination of. a feed water heater,` a pipe leadingtherefrom, a. container for a cleaning compound in lcommunication with said pipe, a steam supply pipe, a branchofrom said pipe leadingL into ,the feed water heater, 'a coil disposed Awithin theconta-iner and connected with the steam pipe,

Aand a pipe leadingl from the .coil yto thefeed water heater.

l. .In an apparatus forrthe vpurpose set forth, the combination .of a. `feed.
