' 1 Claim. (01. 126-73) This invention relates to improvements in .magazine heaters for burning coal and other solid fuels.
While the present invention may be embodied in various useful forms, the form disclosed herein is especially suitable for space heatingby radiation directly from the heater itself. j
However, the invention may be employed with circulation systems. tion is further especially adapted for. retaining The heater-of our invena large amount of fuel so that on one filling it combustion of the fuel progressively from the bottom of the stored quantity to the top thereof.
several days supply of solid fuel is provided with "a large number of perforations in its vertically extending annular wall through which the incompletely burned'gases and smokeescapeoutwardly into anannular space surrounding the fire'pot, where they encounter a fresh supply of air to support and-complete their combustion,
The products of the combustion in the annular space are then returned, in large part through which they are then'discharged into a chimney. 'One of the objects of the invention is to provide a heater having a large fire pot in which can be'stored a large amount of solid fuel, such as A fire pot having a'size ample for containing other perforations near the top of the firepot :and pass from there into the smoke box through coal, and-having a secondary combustion space outside of the fire pot v fuel gases are mixed with fresh air and there consumed.
nularly about the me pot and confined by a wall pose'of radiating heat into the circumambient atmosphere.
Another object of the invention is to provide a heater of the'type described including a fire pot having a top feed opening and surrounded by an annular secondary combustion space for "receiving fuel gases from the fire pot and with means for forcing the products of combustion developing in the annularspace'back again into in which partially burned -'Another object of the invention is to provide -a heater having the foregoing features and hay-'- ing the secondary combustion space located anheated by the secondary combustion for the purthe top of the fire pot before exiting to the smoke pipe.
Otherv objects and advantages of the invention.
will be mentioned specifically hereinafter or will 2 I I :n I become apparent from a perusal of the following specification. On the drawings: Figure l is a perspective view of a heater made in accordance with my invention, with portions thereof broken away to show theinternal construction;
Figure 2 is a vertical central sectional view through the heater;
Figure 3 is a horizontal sectional view on the line III-III of Figure 2; f
Figure 4 is a horizontal sectional vlew'onthe line IV-IV of Figure 2;
Figure 5 is a perspective view of one fthe fire pot sections; and a Figure 6 is a perspective view of showing'the manner of assembling the fire pot from a plurality of fire pot sections.
. Referrin further to the drawings, the heater comprises a base l0 having a plurality of ventilating apertures H for permitting natural circulation of air through the base. Upon the base is mounted an imperforate plate l2 upon which rests the ash pit chamber l3 which is provided with a hinged door M for facilitating the withdrawal of ashes accumulated in the ash re ceptacle l5. 1 The top edge of the ash pit chamber is provided with an inwardly extending flange l6=having an aperture ll of substantial area for permitting upward flow of air from the ash pit-into the secondary combustion space generally indicated as l8. Supported on the flange 16 which has a circular inner margin is a grate supporting ring I! which in turn on its lower flange 20 supports a stationary grate member 2| havinga plurality of ports Him the admission of air'from theash pit into the fire pot. This stationary grate member is provided with pairs of vertically' space'd apart flanges 23 and 24 which furnishlsupport for a horizontally oscillatable grate 25 having projections such as 26 and 2! extending between the flanges. The oscillatable grate may be oscillated by means of a handle 28 which is an extension of the projection 21. A cone or deflector 29 is supported as shown on the grate '25 to elevate the bottom of the fuel bed slightly above thecenter of the movable grate. A plurality of ports 39 provided in the movable grate admit air from the ash pit into the bottom of the fire pot.
Supported also on the ring i2 is a tubular jacket 3|, which in the operation of the device is the principal heat radiating surface and whlch is also apertured at the'front of the heater to ture therebelow, and with notches 35 for interlocking cooperation with fire pot sections, if any are mounted 'thereabove. Each section also ha's-a flange 36 and a flange 37 which inthe assembly shown in Fig. .6 overlap co ti uous fire pot .sec. tions and are bolted thereto, through bolt :holes.
such as 38 and 39.
The number of fire potsections required to I! in the plate l6. Here these fuel gases are completely burned and the heat thereby produced is absorbed in large part by the heat radiating jacket 3|. In view of the fact that the bafiie 40 is located as shown and has only two small restricted apertures 42 and 43 through -which these burning gases could escape directly to the smoke p p the bulk of 'theqproducts of combustion or burning gases Will be deflected by the baffle into the fire pot through the ports 33 in the upper part thereof. These gases may also enter the top of the fire pot through various comprise one fire pot ring is of course optional; dependent upon the size of the fire pot v.to-be built and upon other considerations. Likewise thenumber of superposed fire potflring sections to be employed is also subject to variation. As indicated in Fig. 6, lugs 34 will restin the notches -:-35;.and thus adequately unite the two superposed firings. rLikewise thellugs on the lowest ring sec-- tion will enter into I suitable notches provided in the ring member i3 resting upon the top 'ofthe wash pitrcha-mber.
A top of the fire pot is partially :closed by a abfafiie plate 413 rhaving near its forward edge a large aperture 4| through which fuel'may be in- -.troduced into the top of the fire pot. Additional small restricted apertures 4-2 {and '43 are also elocated as shown near the .front corners of, this baffle plate to eliminate kick back :and ,puffing. These-restricted apertures register with top of the annular space definedby the fire pot and the jacket 3!. .fllhe :marginal edges of the baflie to rest upon *an :inwardly extending continuous flange 44.:on the :jacket. :31, and the edges of the baflle support the peripheral jfiange portion 45 0f 'the smoke box 4.6 whichihas a flanged 'p'ort 4"? for the attachment or the usual smoke pipe. The smoke box "is-provided at its "forward side with a large opening 48 Whichi's normally closed by the door or lid 49, which may be lifted when fuel is being fed into'thefire'p'ot;
the ash pitadoor; l4, TI provide :a draft re :ulat0r -50 :of ordinary construction having ports zregdl'ate'dJbyJsIiding' movement of a gate so that .it'amay regulatably control the admission 'ofair into the ash pit. The hinged door 50 is provided -'SOJth2itf1lh8 movable grate may be actuated by a opening =4l into the fire pot until the fire pot is efnl-l. Assuming that the fuel first introduced has .been ignitedbefore the remainder is introduced,
, orthat there was a layer of fuel-already burning on the grates, the combustion will proceed as fol- .lows: .Air from the ash pit enters through the "apertures .30 and 22 into the bottom of the fire .potiordnitial or partial combustion of the fuel.
i Thetotal amount of air admitted in this manner ...is less than that required for complete combustion- Thelpartially burnt fuel gases pass'radially ,outwardly from the. fire pot through the various ;.ports 33 into .the secondary combustion "space [8 wherethey encounter a .fresh supply of airad- .i riittedirom the ash pit through the front port tion.
For .purposes ofobservation .wemay optionally provide 'an aperture in the jacket 3'! .and cover the aperture With .a plate 52 having-a plurality lorports therein eachof which would becovered by is'ing'lass 55.3., or some other suitable transparent or translucentmateri-al.
When good. draft .conditionsexist in this heater themovablegrate may .be actuated ,by ,a #13001 exsuckethe dust up throughftheenlarged opening li .and deliver. it to the smoke pipe. Ehus the dust willlnot puff out through the draft regulator opening. 1
When theheater is'in operation (there will be some tendency .for thedraft to pull air and combustiongases directly through the .fire pot and fuel inlet port 4| to the .smokestack. ,However the chargenf fuel directly on top of the zone of firein the-fire 3301; will impede such flow of gases to a marked extent. .gases-mayfiow .withless restriction by emerging According-1y, these through the ports 33 radially into the secondary combustion space I8, aided by the-draft therein,
and then back again into the upper end of the firepot and "out through port 4| into the smoke box. While partially burned products of combustion fiow ,into the secondary combustion space L8, they of course encounter an ample supply of fresh. .air and will then become completely burned. Theheat produced by that secondary combustion .is to a large extent radiated to the .surroundingatmosphere through .the jacket 3|.
As indicated, the ports '33 are numerous and quite uniformly spaced on the fire pot wall .to induce uniform egress of fuel gases from the active fire zone in the fire pot at whatever levels itmay exist. The holes should be small enough, however, to prevent loss of solidfuel.
It will, of course, be understood that various I structural details of the invention may be varied through a wide range and that the invention may be embodied in various: forms differingcons1derably.from each other and from the embodiment herein shown, without departing from the principles of the invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwiselthan necessitated by the scope of the-appended claim.
We claimas our invention:
A magazine heater comprising a base having "a frontside .and :a top wall, an upright ash pit defining member ;on said top 'wall'having an open front cylindrical portion inwardly from and substantially concentric with the periphery of the base and laterally extending portions at the sides of the open front of the cylindrical portion terminating at the front side of the base, a grate ring supported by the cylindrical portion'of said member, a tubular fire pot supported by'said grate ring, said tubular fire ot including a plurality of segmental cylindrical perforated plates with ofiset flanges on diagonally opposite ends thereof for cooperating with flanges of the adjacent plate to form a continuous ring, said ring having lugs and lug recesses on opposed edges thereof for mating with an adjacent ring of plates, a jacket on said base surrounding said ash pit defining member and said tubular fire pot and having an opening in the front thereof.
aligned with the space between said laterally projecting portions of said ash it defining member, a door for closing said opening, said ash pit defining member and fire pot being in spaced relation from said jacket except at said opening,
- the space enclosed by said ash pit defining memhaving a smoke outlet, apertures in said baffle connecting the space in the smoke hood with the space between the jacket and fire pot and with the fire pot for creating an updraft, and said updraft being effective to pull dust out of the ash pit chamber through said space between the laterally extending portions even when said door is opened, whereby ash dust will not be discharged through said opening in the jacket.
