UNITED STATES ERNEST H. PEABODY, OF PELHAM MANOR, NEW YORK.

AIR nnefs'rna' FOR FUEL Bonuses.

Application filed April 19, 1923. Serial No. 633,169.

To all whom it may concern:

Be it known that I, ERNEST H. PEAnonY, a citizen of the United States, and resident of Pelham Manor, county of Westchester, State of New York, have invented certain new and useful Improvements in Air Registers for Fuel Burners; and I do hereby declare the following to be a full, clear, and exact deseription of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to a system-0r air control registers for fuel burners, preferably of the mechanical a-tomizing type which finely atomizes the fuel entirely by pressure and produces a hollow conical spray, and

has for its objects to produce a register that will delii'er the required air supply uniformly and in a direction converging to the flame so that each particle of fuel will be supplied with its required amount of oxygen for complete combustion within the cone of fuel as well as on the outside surface.

It is Well known that efficient combustion can be produced only by atomization of the oil into its finest particles. If each particle is 'far enough apart from its neighbor to permit being completely surrounded with invention will now be described in connection with the accompanying drawings, forming part of this specification, in which I have represented my air register in ts pre ferred form, after, which I shall point out more particularly in the claims those features which I believe to be new and of my own invention. y

In the drawings Figure 1 is a central vertical sectional view of my register mounted in a furnace front.

Figure 2 is a view, partly broken away, of the front plate.

Figure 3 is a view of my register partly broken away with the front plate removed.

In the carrying out of my invention, the refractory wall 1 of any suitable furnace is provided with a circular opening 2 into which a conical annular ring 3 is secured by any convenient means such as bolts 4 tothe front plate 5. The inner end of the conical ri-n ang e with the refractory wall 1 of the furnace, which is filled in with plastic refractory material 7.

3 is flanged as at 6 forming a right.

Coaxial with the conical member3 I provide a cylindrical member 8 having a reduced portion or sleeve 9 adapted to hold the burner 10 provided with tip 11, fuel supply 12 and diffuser plate 13. The

burner is adapted to slide withinythe sleeve and be held in adjusted position by means of the thumb screw 14. Spirally arranged deflector plates 16 hold the conical member 3 and the cylindrical member 8 in spaced relation and the latter is provided with openings 15 which are located between the deflector plates 16 and form a plurality of air ducts which converge from the outer to inner portion having a section of maximum restriction near the combustion chamber substantially like the converging nozzle used in elastic fluid turbines of the impulse type for converting pressure into velocity.

Mounted on the sleeve 9 I provide a front plate 20 adapted to slide and rotate to control the air passing into andthrough the air passages in the register.

I provide a plurality of openings 21 in the flat face 19 of the cylindrical portion 8 and in front of these openings I provide a shutter 26 operated by handle 22 suitably guided as at 23 and secured in its adjusted I position by thumb screw 24. ,This shutter 26 is provided with openings 27 similarly arranged with holes 21 in plate 19.

From the foregoing description it will be apparent that the air passages between the conical member 3 and the cylindrical member 8 separated from each other by the spiral partitions 16 converge toward the combustion chamber. Each passage gradually changes in section to maximum restriction at the combustion chamber end.

The air'of combustion in flowing through 1 a passage so proportioned will expand adiabatically to the lesser pressure existing at the throat and issue uniformly as a continuous stream possessed of a definite velocity in a direction convergent to the flame so that it will enetrate' the conical layer of ignited fuel owing from the burner and enter the furnace as a highly incandescent gaseous mixture.
