Y Specification of Letters Patent.
Patented Feb. 14, 1911.
Application led July 218, 1910. Serial No. 574,285.
To all 'whom it may concern:
Be it known that I, HENRY Jaoons, a. citizen of the United States, and resident of Topeka, in the county of Shawnee and State of Kansas, have invented a certain new and useful Improvement in C'ombined Boilers, Superheaters, and Feed-\iater Heaters, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specification.
The objectof my invent-ion is to provide a *combined boiler, superheater and feedwater heater that will produce a. high thermaly efiiciency, and at the same time be of very compact form, requiring as little space for the `generated power as possible.
A further object of my `invention is to provide a-ire-box and combustion chamber that will economically consume any kind of fuel` but more particularly oil fuel.
The invention also consists in certain new and novel features and combinations which will he more fully understood from the following detailed description of the accom- Figure 1 is a longitudinal sectional View of my invention. Fig. 2 1s a cross sectional view taken on the line A-A of Fig. 1` lookingr in the direction of the arrows. Fig. 3
isa cross sectional View taken on the line B-B of Fig. 1, looking in the direction of the arrows. Y
In illustrating my invention I have shown what is known as a Jacobs-Shupert seetional fire-box 1 and a sectional combustion chamber 2 connected thereto as well as to the flue sheet of the boiler.
3 is a combustion chamber located at the opposite end of the boiler or lues, and this combustion chamber is preferably surrounded by a water-jacket 7.v Located adjacent tothe combustion chamber 3. and built on the forward top part of the boiler, is a superheater 4: while a feed-water heater 5 is built on the rear top part of the boiler, as can clearly be'seen in Fig. 1.
The superheater and feed-water heater are built on top of the boiler shell. which shell forms one wall of .the two compartments constitutingr the superheater and feedwater heater, and are, therefore, of crescent shape, as clearly shown in the cross sectional views,
v Figs. 2 and 3.
1 3y reason of the construction just descrlbed, it is apparent that the greatestpossible amount'ot heat from the products of combustion is absorbed by the Water and steam, thereby obtaining a veryv high thefrinal efliciency for the plant.
The cours;x of the products of combustion, after being burned in the fire-box 1, and also consumed in the combustion chamber 2, leads through the smoke tubes of the boiler into the combustion chamber 3. As this combustion chamber 3 is surrounded by the water-'jacket 7, heat will be absorbed from theproducts of combustion as they are passing through the combustion chamber 3 from the lower portion thereof toward its upper end, where the products of combustion are reversed in their course and made to pass backward through the smoke tubes' 8 of the superheater 4. 'After the gases have passed' through the tubes S of the superheater 4f,4 l
they enter the combustion chamber 10 and pass around the steam dome 9 contlnuing through the smoke tubes 11 ot the feed-water heater 5 and are discharged into the smokehox 12, beingV discharged into the atmosphere through the smoke stack 13.
The water which it is intended to heat is forced into the water-jacket 7 surrounding the combustion chamber 3 through the pipe 14. As the water rises to the top of this compartment or water-jacket 7, it absorbs the heat radiated 'from the gases in their passage through the combustion chamber 3. The. water rises in the water-jacket 7 and passes out through the fountain or tee joint 15 into the pipes 16, 1G, see Fig. 2, which carry it. toand through the cheek valves 17 n into the lower parts of the feed-water heater 5, where it is further heated by the products of combustion passing through the smoke tubes 11 of the feed-water heater 5. As the water rises and fills the feed-water heater 5 from the valves 17, 17, it passes out at the top through the fountain or tee connection 18 and into the pipes 19, 19, which carry it to the check valves Q0, 20, see Figs. 1 and 2, through which it passes into the boiler where itis further heated and converted into steam. The steam is carried ott through the steam dome 9 into the steam pipe 21, see Figs. 1 and 2, which leads it into the superheater 4 22 and 23, see Fig. 2, aud is delivered into the steam pipe 24 which carries it tothe engine.
v The injector or feed-Water pump may be connectedY to the pipe 14, keeping the pressure in the water-jacket A'l' and feed-Water heater 5 equal to boiler pressure or ivater may be e'rculated through the waterjaeliet 'l' with a feed-Water pump connected to the fountain l5 and delivering' it into the feed-ivater heater 5; or the feed-water pump may a gain be connected up between the feed- Water heater 5 and the boiler.
The combustion chamber 8 is shown provided with a cinder hopper 25 located at the bot-tom thereof, so that any cinders or dirt,
vthat may collect in this chamber 8 may be easily removed. A man-hole 26 may also be builtin the front Wall of the Water-jacket 7, so that a man may enter the combustion chamber 3 to make any repairs or do Work Aon the fines. The location of the man-hole enables the boiler fines to be readily removed or replaced therethrough.
It will be seen from the drawings that I have arranged my combination in sueh a way as to have. the superhea-ter lt located at an intermediate point. with reference to the course of the products of combustion. The purpose in locating' the superheater. as shown, is to'have it located ata point where the gases are not hot enough to destroy the material of which the superheater is made, yet at the same time contain enough heat to produce the desired amount of superheat to the steam.
Theflues may all be secured in tue lluesheet of the boiler, the superheater, and the feed-Water heater in any suitable manner, but 'they' are preferably welded tothe fluesheets. The .seam Q7 connectingr the combustion chamber 2 to the lire-box l may either be riveted, riveted and welded. or preferably Welded in order to prevent the seam being destroyed by the intense heat of the furnace.
The construction of combustion chamber illustrated permits of the expansion of the boiler tubes and, therefore, the latter may be Welded to the flue-sheet.
The cinder hopper connection pipe Q8, see Fig. 1, through thNwater-jacket 7, may be connected bv rivets and a flange, but preferably by Welding `he connection pipe Z8 to the inside wall 29 of the ce 'nbustion chamber 3. This insures a more reliable joint, as the cinders that collect in the combustion chamber 3 at this point are generally very hot.
I have shown and described what. I believe to be the best form of my invention. but it is `apparent that the same may he altered in anumber of minor details without departing from the spirit of my invention; for example, if preferred the feed-Water may be first entered into the feed-water heater 5 and conveyed from there into the water- ]'acket 7 from which point it. may be carried into the boiler.
By forming the feed-water heater in two sections with the one section located about the combustion chamber 3, it is evident that greater etiiciency is had.
It, is also apparent, that by forming a unitary or integral structure with'the superheater and one section of the feed-water heater built upon the boiler shell, any heat radiating frointhe boiler shell will be absorbed by the water and steam in the feed- Jvater heater section .and the superheater respectively.
I do not wish to be understood as limiting myself to the exact construction'shown and described, but
What I do claim as my invention and wish to secure by Letters Patent iszl.
