JOHN G. :nna r'rm, orflnolvnon, o vramo, cnnanmnssrenoza. or. .qaam o wnrrnsoiv. or ennon, onranxo, CANADA.
To allwhom it may concern: i it Be it known'that I, JOHN C. BEATTIE, of the city ofLondon, in the county of Middlesex, Province of Ontario; Canada, have invented certain new anduseful Imrovements in Water-Purifying Systems for EteamBOilerS, of which the following is a specification. I In-districts where soft water is not available, muchtrouble is experienced from deposits of sediment and scale; in steam boil-.
ers, and my object is to devise an attachment which may be made to existing boilerswithout alterations thereto to effect the precipitation of sediment and scale from the feed water before passing to the boiler.
I attain my object by means of constructions hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is a plan view of the water purifying system applied to a steam boiler; and
Fig. 2 a front elevation of the same.
In the. drawings like numeralsof reference indicate corresponding parts in the different figures.
1 represents part of the combustion chamber of a steam boiler and 2 the feed water well to which water of condensationis led and to which will lead wherever possible a water supply pipe 3 conveying water under pressure from any suitable supply such as a city waterworks system. 4 indicates suitable means for drawing the water from the well and forcing it into the boiler under pressure, such, for example, as an ordinary inspirator or injector. 5 is. the steam supply pipe of the inspirator and 6 the suction pipe. 7 is the outlet pipe of the inspirator, whichis connected with one end of the pipe 8. Thispipe 8 is led through a part of the combustion chamber of the steam boiler. In-its preferred form this water heating pipe is U-shaped, as shown particularly in Fig. '1. The other end of the pipe 8 is connected with one end of the settling tank 9 by means of the pipe 10. To the other end of the settling tank is connected the pipe 11, through which the purified feed water may pass to the boiler.
From the above description it will be seen that feed water above boiler pressure is passed through the water heatin pipe 8, thence through the settling tan 9 and thence to the boiler. In the settling tank W I K I IYING SYSTEM OR swam-nouns.
sediment and scale which would otherwise be deposited in the boiler settles out and maybe withdrawn through the blow-off valves 12. i
To provide for the proper operation of the system, 1 other features must be embodied in the system. As an inspirator will not work satisfactorily if the boiler pressure is below acertainlimit, which limit is usually below the pressure obtainable from a city water supply system, I provide the pipe 13 which connects the water supply pipe 3 with the pipe 7. Between the inspirator and the connection of the pipe 13 I provide the controllingvalve 14. W hen this valve is closed and the valve15 in the pipe 13 open, water from the pipe 3 may pass directly through the water heating pipe 8 without going through the inspirator. back flow I provide a check valve 16 in the pipe 7 between its connection with the pipe 13 and its connection withthe pipe 8. In
the pipe 11 leading from the settling tank to the boiler a control valve 17 is provided. If for any reason the water heating pipe,
the settling tank or other part of the appachambers by two overlapping substantially upright partitions 20, one extending from p f re ifie tion f L t flat nt .Iatented Mar. 22, 1921. Application filed November 26, 1919. Serial No. 340,828. r i
To prevent any i the bottom of the tank nearly to the top and i the other extending from the top nearly to the bottom. The blow-off valves 12 are located one below each of these chambers. With this arrangement a minimum of agitatio'n is caused tothe water in the settling tank by the entry and outlet of the feed ,water and a maximum of settlement is thus obtained.
It will be found that with the system described the objects of my invention as set forth in the preamble to this specification are readily attained.
A further result attained is that a considerable economy in fuel results owing to the water surfaces of the boiler being kept free from scale and sedimentwhich obstruct the free passage of heat from the hot gases to the water Within the boiler. V
What I claim as niyinventionis p 1 The combination with aboiler and furnace of a water heating pipe located within the combustion chamber'of the furnace, but
having its ends extended through the furnace wall; an inspirator adapted for con- 'nection with the steam space of the boiler of the settling tank to the boiler; and a blowoff valveat the bottom of the settling tank; r Y
2. A water purifying system constructed as set forth in claim 1 provided with an auxiliary pipe for. the supply-of Water under pressure connected to the pipe leading from the inspirator to the Water heating pipe; a controlling valve in said water supply pipe; a controlling valve inthe pipe from c the inspirator between the inspirator and the connection with the auxiliary water supply pipe; and a check valve in the pipe from the inspirator between the connection of the auxiliary water supply pipe and the water heating pipe.
3. A Water purifying system constructed as set forth in claim'l provided with an auxiliary pipe for the supply of water under pressure connected to the pipe leading from the inspirator to the water heating pipe; a controlling valve in said water supply pipe; a, controlling valve in the pipe from the inspirator between the inspirator and the connection with the auxiliary water supply pipe; and a check valve in the pipe from the inspirator between the connection of the auxiliary Water supply pipe and the water heating pipe; a controlling valve in the pipe leading from the tank to the boiler; and a bloW-ofi valve in said pipe between the controlling valve and the boiler.
