OIL-ATOMIZER.

Specificatiei's Patent. Patented Sept. 12, 11916..

Application filed October 12, 1915. serial lto. 55,581.

To all whom. it may concern:

\ Be it known that '1, JOHN ROBERT BROWN,

a subject of the King of Great Britain, and

i a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Oil-Atomizers, of which the following is a specification.

My invention relates to improvements 1n oil atomizers for fuel oil, and the object of my invention is to devise an atomizer of s1mple and inexpensive construct1on, adaptable for use with either steam or compressed air,

Fig, 1. Fig. 4 is a view illustrating the manner in which the atomizer is mounted on a furnace front.

Similar figures of reference indicate s1m1- lar parts throughout the several views.

The atomizer is preferably formed as shown in. section in Fig. 1, and is,when in place, mounted on the furnace front as shown in Fig. 4, in which 1 indicates a portion of the end plate forming a furnace' front, 2 indicates the combustion chamber,

. 3 the firebars and 4 the ashpit.

exit of the atomized oil.

The portion of the atomizer exterior of the combustion chamber is preferably conical in design, forming a chamber 5, as shown in Fig.1, from the inner perlpherypf which project into the center a plurality of pin members 6' arranged as shown in Figs.1 and 3, while the portion extending into the combustion chamber is tubular in formation as shown at 7' in Figs. 1 and 4, the end of which portion 7 is enlarged, as shown at 8 and closed, two slots, 9 and10, being cut in the closed end to allow for the A dia hragm plate 11 divides the tubular portion longttudinally into two sections, and an oil nozzle 12 is fitted into the end of the chamber 5 to The end of-this nozzle may beopen, so that the oil will issue directly therefrom, but in the preferred construction shown in Fig. .1, the end is closed and o enings 13 and 14 .are provided in the b0 y of the nozzle, through which openings the oil issues into the chamber 5.

The chamber 5 is adapted for connection to any source of fuel supply and steam or compressed air for atomization purposes, such as that indicated in Fig. 1, in which 15 represents the oil supply pipe connected to the nozzle 12 by the stop valve 16, and 17 represents the alternative steam or compressed air supply pipe in connection with the chamber inlet openings 20 and 21 and entering the chamber on opposite sides of the nozzle 12, steam being fed to the pipe 17 by the pipe 18, which is connected to the steam space of'theboiler, or, alternately,

compressed air may be fed to the .pipe 17 through the pipe 19, which is connected to any suitable source of compressed air supply, both these pipes, that is, pipe 18 and pipe 19, being led to a crossconnection 22 commonto both.

the openings 13 and 14 of the nozzle 12 are Referring to Fig. 1, it will be seen that located directly opposite the respective inlets 20 and 21, and this is the preferred position of theopenings 13 and 14.

The operation of the atomizer will be apparent, and is as follows :The oil, entering the conical chamber 5 through the openings 13 and 14' of the nozzle 12, which nozzle is maintained at a very high temperature by the. impinging thereon of the steam, or compressed air, as the case maybe, comes immediately in contact with the atomizing ,fluid issuing through the respective inlet openings20 and 21 'from the pipe 17 to be heated and broken up thereby and by which it is forced along to the tip of the atomizer, the atomization being completed by the pin members 6, the diaphragm plate 11,'and finallyby its passage through therestricted openings 9 and 10, issuing therefrom in a perfectly atomized state.

What I claim as my invention is I 1. An oil atomizer comprising a frustoconical chamber having inlet openings in its large end and having its small end terminating in a tubular extension the end-of which is 'closed and provided with outlet 55 extend thereinto, all as shown in Fig. 1. passages, a tubular member extending into said chamber, said member being provided with outlet openings arranged respectively opposite the inlet openings of the said chamber, and a plurality of inwardly projecting members disposed within the chamber.

2. An oil atomizer comprising a frustoconical chamber having inlet openings in its large end and having its small end. terminating in a tubular extension the end of which is enlarged and closed and provided withoutlet openings, a tubular member extending into said chamber, said member being provided with outlet openings arranged respectively opposite the inlet openings of the chamber, a plurality of inwardly projecting members disposed Within the chamber and arranged'to obstruct the passage of fluid therethrough and a diaphragm plate disposed longitudinally in the said tubular extension.

3. An oil atomizer comprising a frustoconical chamber having inlet openings in its large end and having its small end terminat- I ing in a tubular extension the end of which is enlarged and closed and provided With a pair of transverse outlet slots, a tubular liquid conduit member extending into the chamber, said member being provided with outlet openings arranged respectively opposite the inlet openings of the chamber, a plurality of pin members secured to the inner periphery of the chamber and arranged circularly and transversely thereof, and a diaand having diametrically opposed nozzle outlets, and steam supply inlets extending into the chamber at diametrically opposite points in radial alinement with the diametrically opposed orifices of the nozzle.

6. In an oil atomizer, a chamber having an extension, a transverse diaphragm in said extension dividing it into compartments, a discharge member for said extension having openings therein, said diaphragm terminating before reaching said me ber whereby vapor mingling space is provi ed.

Dated at Vancouver, B. C., this'QOth day of September, 1915.
