- Pot type burners comprise a metal pot, usually of sheet metal, with a top having an opening for 6 the discharge of flames, and usually having perforations in its sides; oil is delivered to its bottom, and air under some pressure is delivered within a surrounding casing to enter the pot through the perforations in the side walls.

UNITED STATES PATENT OFFICE Application December 27,1937, Serial No. 181,823
9 Claims. (01. 158-86) Our invention relates to oil burners, generally such as are known as pot type burners.
Pot type burners comprise a metal pot, usually of sheet metal, with a top having an opening for 6 the discharge of flames, and usually having perforations in its sides; oil is delivered to its bottom, and air under some pressure is delivered within a surrounding casing to enter the pot through the perforations in the side walls. The 10 flame being started by ignition of oil upon the bottom, or other combustible material within the pot, oil gas is generated bythe heat radiated from the flame within the pot, and in part by heat conducted through the walls of the pot to the oil.
upon the bottom, and thus the combustion continues. Such a burner is a very simple type, and inexpensive, and has come into general use for such reasons. It is, however, inefllcient in that the oil is not thoroughly gasifled, and the flame is a yellow flame, indicating imperfect combustion, and therefore loss of efllciency, and indeed imperfect combustion is further indicated by deposits of carbon in and about such burners, such deposits being characteristic of this type of burner.
It is an object of our invention to provide a generator which may be employed in such burners now in use, or which may be associated with such a burner, either removably or integrally, the better to generate gas from the oil, and to insure complete combustion. When employed in bumers which are already sooted up, it will in a short time effect combustion and removal of carbon deposits.
It is another object to make such a generator for use in a pot type oil burner which may be readily adapted to any such type of burner now in use, or which may be incorporated in or supplied with new burners of the pot type.
It is a further object to provide such a generator which shall be simple and inexpensive in construction, and little subject to burning out or to destruction from other causes in use.
It is a further object to provide such a generator which has incorporated within it means to regulate the supply of oil and for disposing of an excess of oil without interfering with the proper operation of the generator.
With these and other objects in mind, as will appear hereafter, our invention comprises the novel generator, the novel combination thereof with a pot type burner, and the various parts of the generatonall as shown in the accompanying drawing and described in this specification, and
as will be more particularly deflned by the claims which terminate this specification.
In the accompanying drawing we have shown our invention embodied in a form such as is now preferred by us, and associated with a typical pot 5 type burner.
Figure 1 is a perspective'view, with parts broken away and shown in section, of the burner and generator disposed therein.
Figure 2 is an axial section through the genera- 10 tor, and through parts of the burner, illustrating the relationship of the parts in use.
The burner illustrated is only typical, and various forms of burner may be employed, and our generator will be found useful and desirable in i5 conjunction with various types of burner. However, as shown herein, the burner consists of the pot 9 having perforations in its side walls, and open at its top. It is shown herein as having a. flat bottom 9!. This pot'is surrounded by an w outer casing 92, which is closed except as provision is made at its bottom, as indicated at 9%, for admission of air under pressure from any suitable source, as is common in the art. This pressure, entering the space 94 between the pct 23 and 25 the casing 92, can only escape through the apertures 9B, and thus assists in the combustion of the oil gas which is generated within the pot. Oil for combustion is supplied by a pipe 95 entering the bottom of the pot 9 to spread over its bottom 9|. As indicated above, such a burner is only typical of many forms with which our generator is useful.
Usually the pot type burner consists of little, if anything, more than the arrangement just de- 35 scribed. However, our burner includes a generator consisting of a metal hood I, preferably a casting of sufficient thickness and mass to receive and conduct an appreciable amount of heat. This hood is interlorly partitioned by a wall ill to define a central gas chamber Ii and a surrounding oil channel i2. These communicate through apertures IS, the lower edge of which, however, is preferably raised somedistance above the bottom 9| whereon the hood I rests, for a purpose which 45 will appear hereafter.
Gas in the chamber ll escapes through an opening it in thetop of the hood i, about which is formed a marginal ledge to receive an upstanding perforated burner pipe 2; The upper end ofthis burner pipe is suitably closed, preferably by a spreader 3 having a hole 30 for escape of any residue of "gas which has not escaped from the apertures of the pipe 2. The gas which issues from these apertures in the burner pipe is sub- 55 stantially all gas. generated within the hood I, and contains no vapor. Issuing from the aper-. tures 20, it is met by air entering the pot through the apertures 90, and is burned with a blue flame.
Oil is admitted to the interior of the hood 0 from the supply pipe 95 through a tunnel l5, which is of suflicient width that its entrance may readily be placed opposite the exit of the pipe 95, so that substantially all the oil which enters at 95 is confined within the tunnel l5 and directed thereby into the oil channel l2. Whatever -oil escapes, beneath the lower edges of the hood l is negligible. However, an overflow opening it is provided in a wall of the tunnel it or in a wall of the oil channel l2, opening to the exterior of the hood and into the interior of the pot, its lower edge being at a lower level than the lower edge of the opening l3. Thus if oil is supplied in excess of the amount that can be generated as gas, it overflows through the opening l6 into the pot, rather than raising the level within the oil channel It to a point where it will overflow through the openings l3 into the gas chamber ll. Thus the gas chamber II is substantially free of liquid oil, but filled with oil gas.
The oil which is confined within the oil channel 82 is heated to a considerable degree by heat which isconducted through the metal hood E, and is thus conducted to the oil. This oil is gasifled in this annular channel i2 by conducted heat, and rises through the openings l3 into the chamber H. Conduction of heat to the oil within the channel I2 is further assisted by vanes t which are preferably cast integral with the hood, but upon the outside of the same. The upper ends of these vanes rise above the level of the hood into the zone of influence of the flames issuing from the holes 2 in the burner pipe. Thus these cast vanes i are highly heated by direct impingement and radiation of heat from the flames, and conduct this heat to the walls of the hood around the oil channel i2, thus further assisting in heating and gasifying this oil. Furthermore, these vanes extend into any oil which has spilled into the open pot through the opening it, and by conduction heats this oil. The conduction of heat to the oil is further assisted by a horizontal flange fill to which heat is conducted from the vanes d and through the walls of the hood, and which lies in the oil about the exterior of the generator. This oil is also heated by conduction through the walls of the pot, as is ordinarily the case, and by radiation from the flames within the pot.
As will be evident, such a generator might be formed integrally with the pot, or secured permanently to the same. It is, however, well adapted for-installation in pot type burners already in use, and it has been found, when so installed, that it will produce a blue intense flame, where the flame without such a generator was normally yellow. It will, moreover, clear up deposits of carbon or soot which have been formed due to improper combustion.
