FURNACE-FUEL-FEEDING APPARATUS.

Application filed January 10. 1323'. Serial No. 611,713.

In feeding fuel to furnaces particularly pulverized fuel it is desirable to have the apparatus so ftfl'll'lttl that the direction of discharge may be varied. The present invention accomplishes this and in the pre ferred form it accomplished by telescoping arcuate tube By sliding these tubes the direction of the end or inner tube is changed. It is also desirable to have a plurality of delivering conduits preferably giving converging jets and to have the direction of discharge at both jets varied. It is also desir able to have a plurality of jets extending horizontally. The pres nt invention provides such a. structure. Further it is desirable to have the feed through the different jets varied and this is accomplislwl in the present invention. Other details will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a plan view of the device partly broken away.

Fig. 2 a side elevation.

Fig. 3 a section of a furnace opening with a pair of the discharge conduits in elevation partly in section.

Fig. 4 a section on the line AA in Fig. 3.

1 marks the furnace entrance which may be of any desired form, usually an opening corresponding to a door opening, and 2 a pulverizer having a fan discharge 3 delivering to a conduit 4. The conduit is separated into two passages by a plate 5. see dotted lines. Fig. 1, and the air flow through each side of the conduit is controlled by a valve 6 mounted on a shaft and actuated by a lever 7 The conduit terminates in a flange 8 on which flange a discharge device is secured. This di charge device has a flange 9 which is secured to the flange 8 for connecting the same to the conduit. It is provided with branches 10 and 11 in the form of a Y, one inclined upwardly and the other downwardly and the relative flow to these pipes 10 and 11 is controlled by a valve 12. this valve being mounted on a shaft 13 and actuated by a lever 14. By throwing this valve the relative quantity going to the pipes 10 and 11 may be varied making the flow to the pipe 10 greater or less or the pipe 11 greater or less as desired. The lever op crates over a slotted plate 20 through which a locking screw 19 extends. The lever may be locked in any adjusted position by tight citing the screw. Thus the flow of fuel and air through the discharge tubes 10 and 11 may be varied relatively to each other.

The tube 10 and 11 are of arcuate shape A tube 21 also of arcuate form is telescopically mounted on the tube 10. It is supported by guide rollers 24-. in the opening 1. It will readily be Seen that by sliding the tube 21 on the tube 10 the direction of the discharge is varied as well as the point of discharge. A tube 23 of arcuate shape is mounted on the tube 11 and this is supported within the opening on. rollers 24. RV sliding the tube 23 along the tube 11 the dirlction of discharge of this tube may be varied as well as the point of discharge. The tubes 21 and are provided with handles 25 to add to the convenience of adjusting them and the e handles are secured to plates 26 arranged on the tube. A screw 27 extends through the plate 26 against the inner tube thus locking the telescoping tubes in any adjustment that may be desired. It will be noted that there are two pairs of these discharge tubes. one

connected with each passage in the conduit 4 and it will be noted that the discharge conduits of each pair converge so that not only can each discharge be adjusted as to direction but they may be adjusted relatively to each other and the volume of air through each discharge may be varied relatively to the other discharge openings.

What I claim as new is 1. In a furnace fuel feeding apparatus.

the combination with a furnace: of a fuel and air conduit leading to the furnace including means comprising arcuate telescoping tubes for varying through the sliding adjustment of one tube upon the other the 5 direction of discharge of the conduit into the furnace.

2. In furnace fuel feeding apparatus. the combination with a. furnace: of a fuel and air conduit leading to the furnace including means comprising arcuate telescoping tubes for varying through the sliding adjustment of one tube upon the other the direction of discharge of the conduit into the furnace: and means for locking the tubes in admeans comprising arcuate telescoping tubes for varying through the sliding adjustment of one tube upon the other the direction of discharge of the conduit into the furnace; and supports within the furnace for the sliding telescoping tube.

'1'. In a furnace fuel feeding apparatus the combination with a furnace; ot a pair of not and air conduits. each of the tuet and air ronduits comprising arcuatc telescoping tubes for 'anving through the sliding adjustment of one tube upon the other the (11- reetion of discharge of said conduits.

5. In a furna tuei feeding apparatus, the combination with a furnace; of a pair of fuel and air conduits comprising arcuate telescoping tubes having converging discharge openings. the direction of discharge being variable through the sliding adjustment of the telescoping: tubes one upon the other.

In testimony whereof I have hereunto set in hand.

THEODORE JOHNSON.
