APPARATUS FOR EFFECTlNG .COMBUSTION OF LlQUlD FUEL FOR FURNACES OR THE LIKE.
SPECIFICATION forming part of Letters Patent No. 631,612, dated August 22, 1899.
Application filed May 8, 1899. Serial No. '715,982. (No model.)
To all whom it may concern:
Be it known that I, J OHN SoLoMoN VIVIAN BICKFORD, engineer, a citizen of England, residing at Camborne, Cornwall, England, have invented certain new and useful Improvenents in Apparatus forElfecting Combustion of LiquidFuel for Furnaces and the Like, (for which I have applied for a patent in Great Britain, dated October 25, 1898, No. 22,437,) of which the following is a specifiation.
My invention relates to apparat femf fecting conhustion of liquid fuel for heating furnaces, crucibles, retorts, and the like, as I shall describe, referring to the acconpanying drawings.
Figure l is a longitudinal section of apparatus according to my invention. Fig. 2 is an end View of the air-nozzle and fuel-pipe, and Fig. 3 is a section thereof on the line 3 3 of Fig. 1.
a is a chamber having a removable cover b and having in its bottom a bed c of refractory material, such as fire-clay.
d is a pipe projecting into the chamber a. This pipe is constructed at its inner end portion with a central contracted orifice e and a slit f in line witha slit g, extending some distance along the lower side of the pipe d. -A pipe h terminates in a downwardly-directed bend, opening over the piped a little behind its end. The pipe d is connected to a fan or blower of anyknown suitable kind, by which a current of air is sent along the pipe and is discharged bythe central contracted orifice e and the slits f and g. The pipe h is connected to a reservoir in which oil or other liquid fuel is maintained at a constant level, so that a regulated supply of the liquid flows along the pipe h and is dscharged on the upper side of the pipe d, over which it fiows, passing around to the under side, where it is met and atomized by the current of air issuing by the slit g. At first starting the working of the apparatus burning fuel, which may be a wad of asbestos soaked in oil or other conbustible liquid, is placed on the bed c'under the slit g. This burning fuel ignites the mixture of air and atomized liquid, and the fiame receives additional air issuing from the hole e `and slit f, a powerfully-heating flame being thus directed through an opening j at the opposite side of the chamber a into a furnace or chamber containing a crucible, retort, or the like.
Having thus described 'the nature of my invention and the best means I know of carrying the same into practical efiect, I claim-- An apparatus for the combustion of liquid fuel,'consisting of a chamber having a refractory bed and au opening at one side, au air- 'supply pipe projecting into the ohamber at the opposite side and constructed at its inner end portion with a longitudinal slit in its under side, a contracted orifice and a slit leading froni said contracted orifice to said longitudinal slit, and a liquid-fuel-supply pipe terminating in a bend which delivers the liquid fuel upon the inner end portion of said air-supply pipe, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
