8 Claims.
This invention relates to stokers of the type delivering fuel to the firing opening in an upright wall of a furnace and employing an upper fuel distributing member against the underside of which, fuel is propelled in a forward and upward direction by means of a blast of fluid issuing from a distributor jet head for scattering it over all parts of the furnace firebed.
The fuel distributing elements of a stoker of 1 this type are in the proximity of the firing opening and one object of the invention is to provide a construction thereof that will minimize the dust in the firing opening resulting among other things from the fuel striking the under side of the upper fuel distributing member.
The upper fuel distributing member or top deflector because of its proximity to the fire in the furnace will gradually burn away and deteriorate to an extent requiring replacement thereof, and
it is therefore another object of the invention to provide a construction and combination of elements that will prolong the life of the top deflector.
In firing a furnace it is important to maintain an even distribution of fuel over the entire firebed if it is desired to obtain maximum efliciency and economy, it is therefore another object of the invention to provide a construction and arrangement of the distributing elements permitting convenient control of distribution of fuel over the firebed.
Other objects and advantages of the invention residing in the construction, relation and arrangement of elements will become apparent from the following description and claims when considered in connection with the accompanying drawings, in which Fig. 1 is a vertical, longitudinal sectional view through the rearward portion of a locomotive g and the novel stoker, taken on the line l-'l of Fig. 2, parts being shown in elevation;
Fig. 2 is a sectional view taken on the irregular line 22 of Fig. 1;
Figure 3 is a sectional view taken on the lines 5 3-3 of Figs. 1 and 2, parts being broken away;
and
Figure 4 is a sectional View taken on the line 4 4 of Fig. 1.
In the drawings, the letter L refers generally to the locomotive which comprises a firebox [0 provided with a grate! l, and an upstanding rear wall l2 having a firing opening I3 therein. The locomotive cab deck l4 extends rearwardly from the firebox rear wall I 2 below the level of the firing opening l3.
Fuel is conveyed from a tender (not shown) to the locomotive firebox In by a stoker indicated generally by the letter S. The stoker S includes a conduit 15 leading forwardly from the tender, universally connected'at. its forward end, by a 5 ball and socket connection Hi, to the lower end of an elevating conduit 11. The elevating conduit l 1 extends upwardly and forwardly through the cab deck l4 and is surmounted by a casing l8 communicating with and. embracing the firing 10 opening l3. The casing I8 is provided with an aperture l9 opposite and in approximate register with the firing opening I 3, and a door 20 supported by the casing 18 forms a movable closure therefor.
Fuel is conveyed forwardly and upwardly toward the firing opening 13 by a conveyor screw 2| disposed within the conduit H. At its lower end the conveyor screw is flexibly connected within the ball and socket connection I6 to a 20 conveyor screw 22 disposed within the conduit [5. Fuel is conveyed by the conveyor screw 2| into the zone of action of a pressure fluid distributor head 23 located at the lower portion of g.
the firing opening, which is arranged to emit fluid, preferably steam, under pressure for projecting fuel into the firebox.
The lower portion of the casing 18 is recessed in its bottom, as indicated at 24, the recess extending between the side walls 25 and 26 of the casing l8. Within the recess 24 is fitted the pressure fluid head 23, forming the bottom wall of the lower tubular portion 21 of the casing 18. For the purpose of securing the pressure fluid head 23 upon the seats 28 and 29, formed in the respective sidewalls 25 and 26, a set screw 3|] is threaded into each side wall for engaging lugs 3| formed on the rearward portion of the pressure fluid head 23.
The pressure fluid head 23 is divided longitudinally into a plurality of chambers 32, for purpose of illustration four such chambers are shown in the present embodiment, though it is apparent that any number may be provided. Supply lines per portion of the firing opening l3. Any num- 55 ber of rows of jet openings may be provided and they are preferably arranged with the jet openings in staggered relation. The pressure fluid head 23 is provided with a lip 31 extending upwardly and forward from the side edges and the forward edge of the perforated wall 34. The lip 31 functions to retain the fuel momentarily as it rolls or drops over the upper edge of the perforated wall 34 so that all the fuel is acted upon by the blast issuing from the jet openings 35 and preventing fuel from rolling or dropping over the forward and side edges of the wall 34 f of a number of positions about the axis of their and accumulating on the wall 38 defining the bottom of the firing opening.
The top deflector 36 is preferably divided longie tudinally into two substantially symmetrical halves 39 and 40 so that they may be individually adjusted about their respective rearward ends to any one of a number of relative positions about a horizontal transverse axis. The deflector mem-' bers 39 and 40 are provided with the hollow hubs 4| and 42, respectively, interfitted at theiradjacent ends by means of a projection 43, circular in cross section and formed with the hub 4| and arranged to be received in the recess 44 formed in the hub 42. The hollow hubs 4| and 42 are provided with the chambers 8 and 9, respectively,
opening through the opposite ends of the hubs 4| and 42. Fluid under pressure is supplied to the chambers 8 and 9, as for example steam, by means of supply pipes 6 and I. The opposite ends of the hubs 4| and 421 of the deflector members are rotatably mounted in the bearing members 45 and 46, respectively. Recesses 41 and 48 are provided in the upper rearward edges of the casing sidewalls 25 and 26, respectively, in which are received the bearing members 45 and 46, respectively. The bearing members 45 and 46 are provided with flanges 49 and 56, respectively, overlapping the casing sidewalls 25 and 25, re-
' spectively, the bearing members being secured to the casing sidewalls in any suitable manner as by means of bolts passing through the flanges into the casing sidewalls. Thus, by opening the firecloor 26 and removing the bearings 45 and 46,
' the deflector 36 can be removed or placed in position through the opening |9- at the rear of the casing I8. A tongue 5| extending downwardly and rearwardly from the top wall of the casing |8 provides an additional bearing surface for the interfltted ends of the hubs 4| and 42.
The deflector member 40 will now be described in detail, it being understood that the deflector member 39 is similarly constructed. An arm 52 having a chamber 53 formed therein extends downwardly and forwardly from the hub 42 to the firing opening l3, and a plate-like member 54 extends forwardly from the arm 52 through the upper portion of the firing opening at a lesser angle to the horizontal than the arm 52.
The chamber 53 in the arm 52 communicates at one end with the chamber 9 in the hub 42, and a plurality of jet openings 55 in the front wall of the arm 52 communicate with the chamber 53. The jet openings 55 are disposed subjacent the rearward end of the plate-like member 54 and the jets 34, into the fire-box; and they also cooperate with the blasts issuing from the jets 34 to project fuel into the firebox.
The hub 42 is preferably also provided with a plurality of jet openings 56 directed downwardly against the upper surface of the plate-like member 54 functioning to eliminate dust in the firing opening and effecting a cooling action on the member 54, thereby prolonging its life.
In order to control distribution of fuel over the firebed in the firebox the deflector members 39 and 40 are arranged for adjustment to any one hubs 4| and 42, respectively, by the handles 51 "and 58, respectively, which are secured in any 4|] are independently adjustable so that distribution may be controlled over either side of the firebed independently of the other side.
Dpending from the underside of the deflector members 39 and 40 are the forwardly and outwardly curving ribs 65 and 66 respectively. These ribs intercept a portion of the fuel projected against the deflector members 39 and 49 by the pressure fluid blasts emitted from the jet openings 35, and direct it to the rear corners of the firebox.
