Referring to the drawing, I generally indicates Whereas I have described andy shownlherein an outer member. or drum provided with a bottom burners of 'the' hydroxilation" type in which 85 2 having a central air inletaperture 3.

It win be understood the chimney effect, which keeps eddy currents c f .e that the lowest of these apertures is abovethe air from descending toward the bottom of the e maximum level of the fuel admitted through the space. It is highly desirable to prevent downpipe 8. Il indicates a row of secondary air inlet drafts or down eddie: which break up the c har- 75,
and, being relatively narrow with respect to its acteristic mode of two-stage combustion obtaine by burners of the type herein shown.
When downdrafts are prevented, the air penetrating through the primary apertures lli mixes with the hydrocarbon vaporized by the heat of combustion to form a primary mixture. This primary mixture in turn receives its final air supply through the secondary air apertures Il, and burns with a clear flame andwithout y height, substantially isfree from eddy currents from above, due tothe chimney effect caused by its relatively small cross-sectional area. Many variations in detail may be made. As shown in Figure 4, I may employ simply a small Ispace around the oil entrance as in the space dened by the member I2cand the wall S. I can maintain a flame without sooting or carbon deposit by burning a very small amount of fuel.
If I divide the entire space into four, as shown in Figure 2, I can maintain a pilot flame in one section with a very small fuel consumption. Broadly, if a given size of burner burns a minimum of say four gallons 'in twenty-four'hours, one sector is able to burn a minimum of one gallon in twenty-four hours.
In practice, a very small flow of the liquid fue is delivered to the particular space opposite the oil entrance, in the case of Figure 2 the space a. Combustion having been initiated, an up-draft is established due to the relatively narrow cross section of the space c. If only a small volume of fuel is delivered, it is evaporated beforeit can flow into the adjacent spaces a, b, or d.
On the other hand, as soon as more oil than the first space c can evaporate is admitted, the oil will seep into the adjacent spaces a, b and d. As soon as this happens, combustion takes place either around the edge where the members IZ,
yso
I3 contact the side wall 6, or over the top of the Walls I2, I3, and the so-called process of hydroxilation then takes place in all of the spaces, with the primary air apertures I0 supplying the primary air for the final combustion, which takes place at ,or above the secondary air apertures Il. Each of the spaces is free from down drafts or down eddies, because of the above mentionedl If the user wishes to turn down the flame and reduce the heating effect, and maintain a mere pilot llame, he simply reduces the fuel ilowf through the line 9 by operating any suitable valve 9a. Combustion then ceases shortly in the spaces a, b and d but continues in the space c. Owing to the abovementioned long, thin form of the space c, the fuel flow can be reduced to a vary small minimum, without causing down drafts or eddies. s
In the form of Figure 3, instead of dividing. the space within the burner into four segments I divide it into six. 'I'he operation, however,is the same, namely the unitary deliveryY of the oil through the passage 9 to one of the spaces within the burner, with the oil flowing therethrough into other spaces beneath the lower edges of the intervening vertical walls or baffles.
Figure 4 simply divides the housing vinto two spaces, the small one being dened between .the
member I2c and the adjacent portion of the wall and serving as the pilot light when a small flow of oil is maintained. .V
All the forms herein shown have this in common, that the oil is delivered at some common `point and passes through an initial chamber before it can reach a second chamber or additional chambers for combustion. When a small flow of oil is maintained, the oil is all burned in the first cham er. This in effect provides a pilot light for the r t of the device. As soon as more oil is being supplied to the vinitial chamber than can be vaporized and burned therein, the additional unvaporized oil flows through into the additional compartments and is vaporized and burned there.
On a maximum'ow of oil there is full comb tion in all of the various compartments.
