COMBINED BOILER AND FURNACE- SBECIFIGATION forming part of Letters Patent No. 782,906, dated February 21, 1905. Application filed August 31, 1904. Serial No. 222,845-
To all whom it may concern:
'Be it known that we, ANDREW HAIGH and J AMES HEPWORTH, citizens of the United States, residing at the city of Philadelphia, in the county of Philadelphia and'State of Pennsylvania, have jointly invented certain new and useful Improvements in a Combined Boiler and Furnace, of which the following is a speciiication.
The principal object of the invention may be said to be the providing of apparatus that consumes practically all of the smoke generated in the furnaces and at the same time increasing the steam-producing capacity of the boiler by reason of the large heating-surface presented.
The invention consists of the improvements hereinafter described and claimed.
The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a central sectional view of the apparatus embodying the invention, and Fig. 2 is a transverse sectional view of thesame.
Referring to the drawings, a and t are two fire-pots arranged side by side and extending but a short distance beneath the boiler c, be-
ing blocked by a partition or wall provided with dampers d and c. As shown in'Fig. 2, the boiler constitutes what may be termed the roof of the fire-pots and likewise of the combustion-chamber f. Below the boiler c and parallel therewith is what may be termed a sediment-drum g, which extends the entire length of the furnace and for a considerable distance beyond the some in order that access may be had to the interior thereof. A plurality of water-tubes ii are arranged in an upright position between the boiler and drum and suitably secured thereto. As clearlyillustrated in Fig. 2, these tubes extend the entire length of the furnace and boiler and are so spaced that openings extending from the boiler to the drum are left between each tube in order that the products of combustion may be l free to circulate and eventually escape by way of the vent or chimney '2'. It will be understood that water is admitted to the inlet j in the well-understood manner and permitted to fillthe drum g, tubes it, and a sufficient quantity to boiler 0. By this arrangement a large amount of heating-surface is presented and steam caused to be generated in accordance therewith. been relative to steam-generating, the invention is not limited thereto, and the above-described apparatus may be utilized in the relining of oil or similar products, in which event the oil after having been duly heated will have left a deposit of coal-tar by way of the tubes it to the drum g, from which it may be readily extracted by way of the pump connection /r:. l is an agitator located within the sedimentdrum.
A description will hereby be given of the smoke-reducing means hereinbefore referred to. The lire-pots are intended to be used alternately in the sense that after the furnace is once started the fresh fire of the other lirepot passes over the old fire in the other firepot until the old fire needs freshening, when conditions are reversed. This is accomplished by the dampers (Z and 0 being manipulated at the proper time. sumed that the lire in pot a, Fig. 2, is old and that a fresh fire has just been kindled in pot t. The damper c accordingly is closed, thus forcing the smoke to pass between the tubes ]L, which are arranged between the two firepots to pass over the fire in pot 0. Obviously in passing over the old fire the smoke is greatly consumed and the heating units pass by way of the open damper (Z to the chamber.
The above-described apparatus may be readily applied to existing types of boilers and f urnaces without material change of same, which is advantageous. Furthermore, the operation of the apparatus may be described as being continuous. g
It will be obvious to those skilled in the art to which our invention relates that modifications may be made in details without depart- \Vhile the above description has- For instance, let it be preing from the spirit thereof. Hence the invention is not limited further than the prior state of the art may require; but,
Having thus described the nature and objects of our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. The combination in a boiler and furnace of a pair of iire-pots and their eomplemental dampers ranged side by side and beneath one end of the boiler, a plurality of verticallyranged water-tubes depending from the lower periphery of said boiler for its entire length and dividing the said fire-pots longitudinally and a drum extending from end to end of said furnace and having connected along the greater part of its top the said tubes, substantially as described.
2. The combination with a boiler and furnace having a pair of fire-pots and a combustionehamber, of a plurality of vertically-ranged water-tubes depending from the lower extremity of and extending the entire length of the boiler and dividing the said fire-pots and chamber longitudinally and a drum extending from end to end of said furnace,said tubes being connected along its top for the greater part of its length, substantially as described.
3. The combination with a boiler and furnace having a pair of fire-pots and a combustionchamber, the said pots and chamber being sep arated by a partition and its dampers, of a plurality of vertically-ranged water-tubes having vertical spaces between them and depending from the lower extremity of and extending the entire length of said boiler and dividing the said fire-pots and chamber longitudinally and a drum extending from end to end of said furnace, the said tubes being connected along the upper extremity of said drum, substantially as described.
In testimony whereof we have hereunto signed our names.
