Abstract
692,645. Mechanical stokers. BABCOCK & WILCOX, Ltd. Dec. 15, 1950 [Dec. 15, 1949], No. 30644/50. Addition to 692,629. Class 51(i) [Also in Group XXX] In combustion apparatus as claimed and described in the parent Specification regulating means are provided for varying the track lengths on the feed plate over which the fuel particles move. As shown coal from a hopper 1 is fed over a shoot 2 to reciprocating feeding rams 3 which move over an adjustable slide plate 8 below which is a compressed air chamber 9 provided with nozzles 10 for the discharge of air over an upwardly inclined feed plate 11. Extending below the hopper is the front portion of a travelling grate 12 and fuel is pushed by the rams to fall over the inner edge of the plate 8 on to the plate 11 which provides a track along which the fuel particles are carried by the air blast into the furnace chamber 13. The amplitude of the rams 3 is adjustable and the plate 8 may be given an oscillatory motion whilst a drop door 7 may be used to vary the gap through which the rams project the fuel. The travel of plate 8 may be such that when it is fully extended fuel is not intercepted by the plate 11 but passes directly to the grate. A number of feed units each comprising ram, plate 8, plate 11 with associated nozzle may be arranged side-by-side across the furnace. Further, a plurality of slide plates 8 may be arranged across the width of a feed plate 11 each being independently controlled so that the track lengths at different locations across the plate 11 may vary. Automatic means may be provided for separately oscillating the plates. Again the plate 8 may comprise a number of side-by-side strip-like plates arranged in two sets alternating with one another each set being simultaneously movable in opposite directions. The edge of the plate 8 may be of wavy, ziz-zag or castellated form and the plate may comprise two relatively movable laminae-one having an edge of said wavy &c. form and the other a straight edge, movement between the two varying the effective length of the projections of the wavy &c. edged laminae. The laminae may be arranged to move together under the action of automatic oscillating means or they may be separately oscillated with different amplitudes of movement.
