ATo'MIzEE BURNER.

Application led May `10, 1921. Serial No. 468,318.

To all whom 'it may concern.'

Be it known that I, CHARLES LINKE, engineer, citizen of the French Republic..residing at Paris, Department of the Seine, in France, and having P. O. address 10 Rue Jean Jacques Rousseau, in the said city, have invented certain new and useful Improvements in or Relating to Atomizer Burners; and I do hereby declare the following to be a full, clear, and exact. descriptionof the invention, such as will enable others skilled in the'art to which it appertains to make' and use the same.

Burners actually in use such as mechanical atomizing burners or blast burners are subject to the following inconveniences. The first class commonly require high pressure, careful filtering and an almost absolute uniformity of the temperature required for preheatin the combustible. The second type ordinari y require an auxiliary motive force which is out of all proportion with the result obtained.

The present invention has for its object an atomizing burner which permits of the delivery of the combustible to the burner without pressure and which requires during the atomization a power comparatively small relatively to that developed by the burner. The action of the presentburner is based on the effect of mechanical `attenuation produced on the combustible which is fed in a continuous manner on to a member adapted to be rotated at a high speed and provided, if desired, with grooves or recesses or suitable vanes. I

The particles of combustible which in their trajectory meet with no obstacle when projected into the furnace through the escape orifice of the burner are projected in Vthe form of a fine 'spray or mist particularly suitable for rapid combustion. The apparatus is provided with an arranglement for the recovery of such portion of t e liquid as is errantly projected against the interior walls of the apparatus and the feed of fresh combustible is effected through an orifice capable of movement concentrically to the aforesaid member, thusrensuring a projection, in which the direction of the jet can be controlled and regulated as desired.

' 1n order that the invention may be clearly understood reference is made to the accompanying drawing which shews several constructional forms of burner in accordance with the present inventlon.

Figure 1 is a section of a disc-atomizer.`

prises a disc-wheel 1 driven by a pulley 2,

the combustible being admitted thereto by a passage 3 and a tube 4. The combustible falls onto the wheel 1 rotatable at high speed and is projected therefrom in an atomized condition through the opening 5. The lower part of the apparatus is in the form of a sump 6 so as to ensure the concentration or collection of the non-atomized liquid which is drawn through the passages 7 in the disc- -wheel 1, which atomizes the liquid and reprojects it.

Figure 2 shews the application of a discatomizer to a circular burner for round Yboilers for a central heating or cooking burner, etc. The disc-wheel 1 is mounted on a tube 14 which receives its rotary movement from a pulley, not shown, situated be-l low and is supported on a standard 15 provided with a ball race 16. The feed tube 17 for the combustible passes through the tube 14 and carries at its upper end a tube 18 which directs the combustible upon the wheel 1. The apparatus is/completed by a cast iron hood 19 to which is secured the feed tube 17, a wing nut 20 permitting of the tube 18 being set in any desired direction. The atomized liquid is projected through the space 21 provided between the lower part of the hood 19 and the upper edge 22 of the body of the apparatus. The non-atomized liquid passes through the rotatable tube 14 and4 yis fed anew through the tube 17 onto the wheel 1.

Figure 3 shews the same arrangement but with two disc-wheels 1, 1 which ensure regularity of working and a greater' output.

Figure 4 shews an atomizer comprising a wheel 8 provided with vanes 9 and an adjustable spraying guide 10. The errantly projected liquid is recovered through the passage 11'.

In Figure 5, the atomizer comprises two Vaned wheels 8, 81, the lower wheel ensuring the recovery of the errantlywprojected liquid. Of the various structural modifications of the above apparatus, mention may be made of the use and injection of steam at any suitable point in order to effect rotation of the vaned wheels and at the same time to assist in the spraying of the combustible. Such a construction with an injection tube 23 is shewn in Figure 5.

In the arrangement shewn in Figure 6, the feed of the combustible is effected through a passage 12 and a spraying guide 13 and the vanedy wheel 8 is so situated as to ensure the recovery of the errantly projected liquid.

Claims: Y

1. In a Vliquid fuel burner the combination of an elementrotary on a vertical axis and adapted on rotation to project centrifw of a rotar inse-,35e

gally from its periphery and in attenuated form liquid fuel fed., to it, a receptacle for liquid fuel arranged beneath said rotary element, the arrangement being such that the said rotary element in its lower part may lbe immersed in liquid contained in said receptacle, said rotary element being further provided with a passage extending upward within said rotaryl element r`'and opening below within said receptacle and opening above to a surface over which on rotation liquid will flow centrifugally.

2. In a liquid fuel burner the combination element adapted to throw in finely divi ed formcentrifugally from its surface liquid vfuel fed toit, and a member` arranged adjacent said rotary element and adjustable relatively. to said rotary element and by virtue of such adjustability adapted to regulate the quantity of fuel so centrifugally thrown from thedisk.

In testimony whereof .I ax my signature.
