FEED-WATER-HEATING CHAMBER.
SPECIFICATION forming part of Letters Patent No. 549,512, dated November 12, 1895. Application filed June 14, 1895. Serial No. 552,849. (N0.mode1.)
T0 at whom it may concern.-
Be it known that we, JOHN WV. HOLADAY and CHARLES F. CASE, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Hot- Air Water-Heating Chambers for Boilers; and We do declare the following to be a full, 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, reference being had to the figures of reference marked on the accompanying drawings, which form a part of this specification.
Our invention relates to feed-water heaters for boilers. Its object is to provide means for utilizing the hot air and gases of the furnace of the boiler to heat the water as it is being forced into the boiler.
In the accompanying drawings, Figure 1 is a section and side elevation of our invention. Fig. 2 is a section and front elevation thereof, and Fig. 3 is a plan and section of the same. All of these figures are partly broken away.
Referring to the drawings, 1 represents the front casing of a boiler-furnace.
2 2 are the doors of the boiler, and 3 the furnace-doors.
4 represents the ash-pit doors. In each of the side walls we construct a flue or chamber 5, running from the front to within a short distance of the rear of the casing, where it communicates with the chimney by a suitable passage or flue-chamber way.
6, Fig. 3, is an opening from the furnace into the fine 5. At the front the fines are closed by doors 7 7. The fiues contain a series of pipes or coils 8 8, the two series being connected by a pipe 9. The water is brought to one series by a pipe 10, passes through this series of coils, then by pipe 9 to the other series, after which it passes into the boiler by pipe 11.
The passage leading to the chimney has a damper in order that the circulation through the flue 5 may be cut off at anytime when desired.
In operation the hot air and gases from the furnace enter by passage 6 into the flue 5 and traverse along and around the coil and then through the open damper into the chimney. When the temperature within the heatingchambers is sufficient to heat the water in the pipes therein, the damper may be closed and the chambers become dead-air chambers; but when it is necessary to increase the heat within said .chambers the damper can be opened and a fresh supply of hot air can be introduced and circulated through said chambers. By means of this construction and arrangement the temperature can be regulated within the heating-chambers, as necessary. Whenever the damper is open there is an active circulation of heated air through the heating-chambers 1: a the flue-chamber to the chimney.
IVe have shown as our preferred construction the water as passing through one coil first, then across and through the other, and then into the boiler; but other and various kinds of coils and also of flues may be used without departing from the spirit and scope of our inventionas, for instance, the feedwater on reaching the coils may be divided and pass part through one series of coils and part through the other. The flues, instead of having the current of hot air flowing through them, maybe closed and receive heat only by conduction through the walls; or the coils can be located in some remote part of the furnace, either lengthwise or crosswise, or may be situated in the chimney or a flue leading thereto.
\rVe have shown in the drawings a furnace especially adapted for burning spent tan as fuel; but it is obvious that it may be so modified or changed as to adapt it for other purposes without departing from the spirit of our invention.
We claim In afurnace the combination of water heating chambers located in the overhead walls thereof, transverse openings in the partition walls at each end of said chambers, Water pipes Within said chambers, a connecting pipe uniting the water pipes in said chambers, supply and boiler connections for said 111 testimony whereof We affix our signawater pipes, Vertical draft flue chamberson tures in the presence of two witnesses. each side of the boiler between rear portion of said heating chambers and the chimney and JOHN \V.
