HEATING DEVICE.
Specification of Letters Patent.
Application filed September 4, 1908. Serial No. 451.631.
To all whom it may concern:
Be it known that I, Ormnnns Fon'rn, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Heating Devices, of which the following is a specification, reference being had therein to the accompanying drawin This invention relates to that class of feed-water heaters utilizing the furnace gases to heat the water and located usually in the fire box, and the invention consists of an improved form of device in the nature of a water casing or diaphragm adapted to be fixed in the lire box and constructed to provide for a supply of air at such point in the fire box that a perfect combustion of the furnace gases will be created and all the smoke effectually consumed.
In the accompanying drawings: Figure 1 a longitudinal section through a furnace fire-box and a portion of the boiler, showing my improved device applied thereto. Fig. 2 is a transverse sectional elevation on the line 22 of the preceding figure.
Referring to the drawings: My improved device consists of a casing or diaphragm A, of flat form, through which the feed-water is circulated, and which extends transversely within the fire-box, thereby dividing the same into two chambers, a front one B in which the fire is built and which constitutes the fire-box proper, and a rear one C constituting a combustion chamber, which chambers connect at their upper ends, as at D, through a contracted space between the crown sheet of the fire box and the upper end of the water casing, the products of combustion being thus compelled to pursue a circuitous path upward before entering the boiler tubes. The water casing is constructed of two metal sheets extending parallel with each other, with a space between them for the circulation of the water, and is formed with two legs or chambers, a. front one E, and a rear one F, which comnumicate at their upper ends and are separated some distance from each other, their lower ends being closed and seated and firmly secured to the g ate bars by means of angle plates (Z and cl, the former being bolted to the front wall of the front leg and to the grate bars, and the latter being bolted to the rear wall of the rear leg and to the grate bars, thus maintaining the easing in an upright position in the fire box with a vertical space between the two legs, constituting an air chamber G extending between the two legs across the the box from side to side. At its upper end this air chamber communicates with the cont acted passage D, by means of a number of openings g and 9, extending through the walls of the casing where the two legs join each other, which openings may be formed by a number of hollow stay-bolts threaded in the walls, as shown in Fig. 1. At its bottom the air chamber communicates with the outside atmosphere through a suitable opening or openings ll, which are adapted to be closed by a valve or door I, so as to properly control and regulate the air supply.
In the operation of the device, the fire is started in the front chamber 13 and the products of combustion, gas, smoke, etc., are cr used to flow upward over the upper end of the water casing and through the contracted space D bet ween the same and the crown sheet, at which point the air flowing from the air chamber through the openings r in the apex of the casing, mixes with the gases and sets up an intense and perfect combustion, thereby burning the gases and smoke, and flowing into the rear combustion chamber and finally entering the boiler flues, all smoke in this manner being effectually consumed and the greatest heating effects secured for the amount of fuel employed. It is seen, therefore, that the water casing in the form described and shown performs the three-fold function of deflecting the prodnets of combustion upward so that they will not pass directly into the boiler llues; of heating the water fed to the boiler; and of providing for the admission of air to the fire box at a point where, in mixing with the products of combustion, a perfect combustion will be created and all smoke consumed.
The water is supplied to the casing or diaphragm by means of a pipe K entering the base of the front leg, and from the cas ing the water enters the boiler through a pipe L extending from the rear leg and communication with the boiler, thus providing for a proper circulation of the feed water to the boiler.
Access may be had to the interior of the legs of the casing for the purpose of cleaning the same, by the provision of suitable hand-holes M and M applied respectively to the inner walls, as shown in Fig. 1.
Patented Mar. fl, 1910.
(iii
Having thus described my inventiomvvhat I claim and desire to secure by Letters-Pattent is as follows:
1. In combination with a fire-box and boiler, an upright impervious water heating casing extending transversely across the firebox with its upper end terminating a short distance below the top of the fire-box to leave a contracted space for the passage of the products of combustion, an air chamber at the rear side of the water casing closed on its four sides communicating at its upper end directly with said contracted space so as to furnish air to the products of combustion at this point, and a combustion chamber at the rear of the air chamber and communicationg with said contracted space, which combustion chamber receives the mixture of air and gases before they act on the boiler.
12. In combination with the tire box, a water casing therein comprising two water legs communicating with each other at their upper ends and separated from each other to produce an air chamber, means for the admission of air into said chamber, and air escape openings at the upper end of the casing.
3. A feed-water heater for fire boxes consisting of a casing comprising two separated water legs communicating at their upper ends, and provided with air admission openings extending through the walls of the casing.
4. In combination with a fire box, a water heating casing situated therein and comprising two communicating water legs extending across the fire box and dividing the same into a front chamber or fire box proper, a rear combustion chamber connecting with the front chamber at the top, and an intermediate air chamber communicating at its top with the front and rear chambers, and means for the admission of air to the air chamber.
In combination with a fire box and boiler a feed-water heater consisting of a water casing comprising front and rear water legs extending transversely across the fire box and communicating with each other at their upper ends, means for supplying water to the front leg, and means for conveying the water from the rear leg to the boiler.
In testimony whereof I affix my signature in presence of two witnesses.
