CRUDE-OIL VAPORIZER AND-BURNER.

lo kill w]: om it may concern Be it lmown that I, Jim-rs G. CLARK, citizen of the Dominion of Canada, residing at Vancouver, in the Proriiu-e of British (lo- .lumbin, Canada, have invented a. new and.

useful Crude-Oil Vaporizer and Burner, of which. the following is a specification.

This invention lclates to a crude oil. vaporizer and'hurner and belongs to that class wherein the vnporous fluid generated from the crude oil is intimately mixed before dclivery to the burner with. superheated. steam,

' the generation of the vaporous fluid and the the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure l is a vertical longitudinal section through the device, Fig. 2, a cross section on the line A. A looking in the di ction of the arrow, Fig. 3, a cross section oh he line B B looking in the direction of th arrow, and

F lg. 4, a longitudinal section of the mixer these drawings 2 represents a. circular lali forming the front plate or hose oi" the urner to which plate the several parts of the casing, etc, are secured and by which zrtt '1 ch eel to the front plate of the furnace or comhustion chamber of a boiler or the like.

A hollow cylinder 3 having a closed and 5 in the center of which is-an aperture G deliveringthe combined oil vapor and steam to the burner nozzle 7, is secured by any convenient means to the front plate 2 so as livery to form a closed cylindrical. chamber 4. Through the axial is passed a control valve and mixing ('lmur her which will be desoribed'later. $ccurcd tothe Same front plate 2 so as to he concentrio with the cylinder is a cylindrical cos ing 20 leaving an annular space 21 through which the air for combustion at the burner is allowed to past; through apertures 26 in and to enable this'air for combustion to be well heated prior to deto the Home 'of the burner the casing 20 is carried beyond the 1d plate' 5 to which Specification of Letters Patent Application filed October 21, 1910. Serial No. 588,332.

center of this chamber 4 Paton tot! Oct. 24, 191].

the burner nozzle secured and is doubled back, as at 22 to a position close to the end plate 5 leaving u space 27 between the inner end of and 5 for delivery of the air to the burner.

To insure that the entering air to support combustion is lu'ought into close contact with the wall of the casing: next to the burner flame a cylindrical partition 22 seated at 24-. on the entl o't the (iyll'fldht' i} and. is carried forward toward the rnal ol the caning 20 Where it doubles around to 22 and against the doubled cod projections 25 from the end of the partition 23 bear against the. inner end of. the caning so that the purtition 2 3 is held in place upon its scat 2 1i.

A steam pipe 8 insierted throw'h the front plate 2 which pipe passes directly through the chamber 4 and within the easing projection. 22 formed into a coil, the end of it being conducted back from the inne coil and is passed through the end plate at 10 into the chamber 4 Where these pipes pars through the end plate 5 they may he gland-packed in. any suitable manner that the pipe may be free to expand and contract. An oil pipe 30 is passed also through the front plat-c 2 and is coiled within the chamber 4, the coil commencing at the end farther from the font plate and passing through that plate to be connected at 31 to the pipe ll which pipe is screwed into n bushing 15 in 'e lj'aich a needle valve 13 seats, which Valve is controlled by a handle 14 on the outer end, of the needle valve stem.

The bushing .15 1S screwed into the end of a casing tube 12 which is secured on the end :3 of the cylinder 3 and projects into close proximity with the end, plate 2. The open time 32 of the needle valve delivers into a conical cavity 16 which is provided with it series of apertures by which the escaping crude oil vapor'ous tluirl is diffused, and the ontshle of the bushing '15 where it isgcrewcrl into the tube 12 is furnished with a series of (loop angled grooves 17 through which steam is delivered to mix with the (liii'used vuporous fluid. The inner side of the puss'uge' 6 through which the mixed vuporous fluid and steam is delivered to the burner nozzle 7 is provided with a spiral groove 18 which tiltl-w' in mixing the vaporous fluid and straw rtl'rclually together.

In operation the steam delivered at 8 1s superheated tlurin its passage through the coil Shcforc it is rlhlivered into the chamber 4 through its proximity to the flame from the burner nozzle 7. The crude oil admitted at to the coil within. the steam filled chamber 4 is vaporized. by the heat therefrom and the va or is delivered at 31 into the pipe 11 from w ich it is admitted through the needle valve into the cavity of the diffusing cone 16. It is here mixed with the superheated steam from the chamber 4 which passes around the end of the casing pipe 12 and is deliver-d through the rooves 17 at an an 1e that will cause acircu ar motion favora le to efiicient mixin which circular motion is reversed as t e vaporous mixture passes through 6 and in contact with the spiral grooves 18. As the mixture escapes through the burner nozzle 7 a supply of heated air which has been admitted at 26 and has been heated in its passage through the annular space 21 before delivery at 27 to the burner is furnished to the flame by which eflicient combustion of the mixture is insured.

It will be obvious that if the burner is used for a urpose where steam is not available for de ivery to the pipe 8 a small quantity of water may be admitted thereto which will become steam in its passage through the coil.

A steam connection 85 may be made by which in the event of the needle valve or burner nozzle becomin obstructed the same may be blown throng in which use'the crude oil su ply will be closed by a valve external to the device or if found necessary the oil coil may also be blown through.
