OIL BURNER.

Application filed October 10, 1923.

To all fw 710m t may concern.'

Be it known that I, ONEsIMn DANDURAND,

a subject of the King of Great Britain, and

residing at the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented a new and useful Oil Burner, of which the following is the speci- .iication The invention relates to oil burners as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and speciiically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the inventionare to facilitate the burning of oil in heating and other plants; to economize in the consumption of fuel particularly in dwellings and pub-lio buildings; to eliminate the use of auxiliary suction devices in such plants; to furnish the burners at reasonable price well within the reach of all consumers and avoid coagulation of the fluid and consequent blocking of the ports; and generally to provide in an oil burning system low cost in regard to production, efficiency in operation, durability in the machine, and simplicity in respect to maintenance.

In the drawings Figure 1 is a plan view of the parts to the system.

Figure 2 is an elevation of the burner from one end.

Figure 3 is an elevation from the other end.

Figure 4 is a side elevation of the several elements.

Figure 5 is a longitudinal sectional view on the line 5-5 of Figure 1.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the primary burners 1 and 2 are preferably in parallel arrangement and suitably spaced, each having a plurality of jet orifices, here shown as 3, 4 and 6 and 7, 8 and 9 in central longitudinal rows, though they may be in lesser or greater numbers according to the capacity of the installation and also having the jets 10 and 11 respectively at the inner sides of the aforesaid rows.

The Secondary burner 12 is also shown as Serial No. 667,607.

parallel tothe primary burners 1 and 2 and therebetween, though at a much low-er level and having a plurality of jet orifices 13 in much greater numbers than the primary burners and in longitudinal rows.

rlhe primary burners l and 2 at one end are connected by the pipe 14: and this pipe is connected to the oil supply tank 15 by the pipe 16 having the shut oii' valve 17, the tank 15 preferably contains crude oil. 65 The otherl ends of said burners 1 and 2 are connected by the pipe 18, the steam gland 19 being introduced in said connection 18.

The pipe 18 is connected to the secondary burner 12 by the pipe 20, so that the oil 70 entering the burners 1 and 2 exudes a vapor which is consumed from the jets and the oil and unconsumed vapor flows on to the secondary burner 12 and is finally and fully vaporized and consumed at the jets 13.

rIhe gas consumed is 0f course not only the vapor from the oil, but is a hydro carbon gas, as steam is generated in the stand pipet form of casing 21 which is connected to a water tank 22 by the pipe 23 having a shut S0 off valve 24: and from said tank 22 the system is supplied with one half gallon of water to every gallon of oil, or thereabouts. The steam generator casing 21 is connected to the steam chest 25 by the pipe 26, the steam 85 being superheated in this chest, and flowing on through the pipes 27 and 2S to the burners 1 and 2, the additional gland 29 being provided in the pipe 28.

It will thus be seen that the expansion of the steam in the chest 25 will cause it to flow at considerable velocity into the burners, where it mixes with the vaporized oil and carries the oil particles with it through the' several jets, where combustion takes place due to the first ignition. A pan 30 may be' provided for a preliminary heating or any other suitable means and any infiammable material is burned in the pan.

What I claim is :u

l. In an oil burner, a primary steam cylinder connected from one end to a water supply, a superheating steam chamber connected to the other end of said cylinder, primary oil burners having jet orifices, and 10a connected from one end to an oil supply and to the ends of said superheating chamber and a secondary oil burner connected to the other ends of said primary oil burners and having a greater number of jet orifices,

lill

neoted to said generator, pipe connections from said chest, to said pair of burners, an oil tank, a Water tank, pipe connections to said pair of" burners from said oil tank having a shut o' valve therein:v and? pipe eonneotions to said generator from said Water tank having a shut off valve therein.
