STEAM-GENERATOR.
SPECIFICATION forming part of Letters Patent No. 643,368, dated February 13, 1900.. Application filed March 9, 1898. Renewed January 17, 1900. Serial No. 1,797. 1N0 model.)
T0 crZZ whom it may concern.-
Be it known that I, GEORGE H. WATSON, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Generators and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
It is the object of this invention to improve the arrangement and construction of the circulating devices for steam-generators in such manner as to afford easy and ready access for inspection, cleaning, and repairs and to hasten the generation of steam and accomplish the best results in the economy of fuel.
My invention consists in the combination, with a steam-boiler and a sediment-collector located outside and at the rear of the boilersetting or furnace, of a header or headers situated outside the furnace between its rear wall and the sediment-collector and communicating with an upper part of the sedimentcollector, tubes having their rear ends expanded into openings in the front of said header or headers in line with rear openings that are closed by caps or plugs, the said tubes being extended forward through the rear furnace-wall and through the combustion-chamber to connect with an upper forward portion of the boiler, and a return pipe or tube leading from a lower rear portion of the boiler and communicating with a lower portion of the sediment-collector, all as hereinafter described and claimed.
In the annexed drawings, illustrating the invention, Figure 1 is a part-sectional side elevation of my improved steam generator. Fig. 2 is a plan of the circulating devices. Fig. 3 is a front elevation of the steam-generator with the furnace-front removed.
The boiler 1 may be of ihe'ordinary horizontal type, provided with internal fire-tubes. Outside the rear furnace Wall 2 there is placed a sediment-collector 3, that is preferably of upright cylindrical form. The sediment-collector 3 is located at such distance from the rear furnace-wall 2 as to allow ample room for access to a transversely-arranged header or headers 4, located between the said furnace wall and the said collector. By means of pipes 5, elbows 6 7, and couplings 8 communication is established between the header or headers 4 and an upper portion of the sediment-collector 3, on opposite sides thereof. While I have shown, preferably, two headers located transversely in line with each other outside the rear furnace-wall, it will be obvious that a single header of suitable length might be arranged to occupy the space of the two headers.
In the front of the header or headers 4 there are suitable openings into which are expanded the rear ends of forwardly-extended circulating and steam-generating tubes 9, that are passed through the rear furnace-wall and through the combustion-chamber 10 and thence above the bridge-wall 11 and grate 12 to connect with a header orheaders 13 at the forward lower portion of the boiler. These forward headers 13 connect, by means of elbows 14, pipes 15, and suitable couplings 16, with the forward upper portion of the boiler, preferably as shown or in any other convenient and appropriate manner.
The circulating and steam-generating tubes 9 should be of such character as to be capable of easy and convenient expansion into appropriate openings provided in the rear headers 4: and forward headers 13, each of which is also provided with openings closed by caps or plugs 17 and 18, respectively, arranged in line with the several circulating-tubes 9, so as to facilitate the work of expanding said tubes into the headers and to afford conveniently ready access for inspection, cleaning, and repairs of'the tubes and their headers.
It is preferable to have the circulating and steam-generating tubes 9 straight throughout their length that they may more readily perlnit the passage of cleaning instruments or devices. They are preferably somewhat inclined in an upwardly and forward direction to promote circulation from the sediment collector to the forward upper portion of the boiler. Anyconvenientnumberofsuchtubes may be employed, so that by the extent of surface exposed in the passage of such tubes through the combustion-chamber and above the grate there will be a corresponding increase in the rapidity of circulation and steam generation.
By locating the rear header or headers 4; outside the rear furnace-Wall and providing ample room for access to the caps or plugs 17 the tubes 9 can be readily cleaned as frequently as may be necessary and at the point where they would be most likely to become clogged or obstructed.
To complete the circulation, a pipe connection 19 is arranged to lead from a lower rear part of the boiler 1 to the sediment-collector 3 below where it connects with the rear headers. Thesediment-collector is provided with the usual blow-off devices and may have an inlet for feed-water, or the feed-water may be introduced into the boiler direct, if so pre-' ferred.
Between the furnace-front 20 and lower forward portion of the boiler 1 there is a screen or partition 21, of tile or suitable refractory materiahto divert the products of combustion rearward along the circulating and steam-generating tubes-L9 and to the rear end of the boiler to pass out throughthe usual fire-tubes therein.
The described arrangement and construction of circulating devices not only afford the greatest convenience of access for frequent inspection and forany necessary cleaning and repairs, but will so promote the circulation asto greatly diminish theusual liability to incrustationor scale. Any sediment or scale that may collect will be rapidly removed, and a rapid generation of steam will be effected with large economy of fuel.
What I claim as my invention is The combination with a steam-boiler, the furnace, and a number of heating and circulating pipes or tubes arranged in the combus tion-chamber directly beneath the boiler and extended through the rear furnace-wall, of a forward header or headers into which the forward ends of said pipes or tubes are expanded, pipes or tubes connecting said header or headers with an upper forward portion of the boiler, a sediment collector located outside the rear furnace-wall, a rear header or headers between said sediment-collector and the rear furnace-wall and into which the rear ends of said heating and circulating pipes or tubes are expanded, pipes or tubes connectingsaid rear'header or headers Withan upper part of the sediment-collector, the said forward head ers and rear headers being each provided wit-h opposite openings in line with said circulating pipes or tubes,-caps or plugs closing said openings, and a pipe connecting the rear lower part of the boiler with a lower portion of the sediment-collector, substantially as described.
In testimony whereof I affix my signature in'presence of two witnesses.
GEORGE H. WATSON.
