The lower half 22 of the dasirlg ortiofi 12 serves as :1 Well 61'' sump t6 which oil may overflow fromthe cemhfistibfl chaniber thr'dttgh an opniiig 23. ,Thi (Wei-flow bf oil may be discharged froth the Well 22 through an outlet 24. By vi'itue of the 'spier-lik cdns'trfictidir of the fei'wa'rd end ofthe casihg'member 12 there'ere previ'ded additional etmophei'ic openihg leading to the interior of a combustion eiieihher gbrpve the rfozzle, as SWQWH it 23,
I have provided a porous core in which for a minimum core diameter there is a max imum of burning surface upon which the fuel oil may burn. My hollow Cylindrical core, which is open at both ends and the forward end of which abuts the shoulder 26 formed by the superheater 14, is provided with an interiorly corrugated surface in the form of longitudinally-extending, radiallyprojeeting fins or ribs 27 constructed of the sameporous refractory material as the core.
The fuel oil is brought to the outer surface of this porous core by feeding through a fuel pipe 28 to a longitudinal cored-out portion 29 of the casing 10. The casing is cut away longitudinally at 29 adjacent the core 11, as shown in Fig. 2, so that the oil may percolate down through the core ll and burn on the surface of the several fins. Through. the use of this type of core, I greatly increase the burning surface of the core and permit the burning of a greater quantity of the oil in a small confined burn er, from which the heat may be projected for use as desired.
I also provide means for furnishing air and steam to the combustion chamber in such quantities as may be necessary to burn the oil supplied to the burner.
What I claim is:
1. In a fuel oil burner, a hollow combustion chamber, said chamber being open at one end and having jet producing means positioned at the opposite end adapted to project a vapor jet t ereinto said combustion chamber. having inwardly extending fins formed of orous refractory material through which uel oil may percolate, and means for feeding oil thereto.
2. In a fuel oil burner, a casing, a removable hollow corrugated refractory porous core adapted to be received within said casing, means for feeding fuel oil to said core to be burned on the interior thereof.
3.111 a hydrocarbon burner, a removable hollow casing core having inwardly extending ridges formed of porous refractory material through which liquid may percolate, said core being open at one end for the dischar e of the products of combustion and PIOVldBd at the opposite end with means adapted to project a vapor jet thereinto.
4. In a fuel oil burner, a hollow combustion chamber formed of porous refractory material having inwardly extending radial fins through which fuel oil may percolate to be burned on the interior of the chamber.
5. In a fuel oil burner, a hollow combustion chamber of porous refractory material having longitudinally-extending inwardlyprojecting fins throu h which fuel oil may percolate to be burne within the interior of the chamber.
6. In a hydrocarbon burner, a hollow combustion chamber of porous refractory material having "an :interiorlfi corrugated surface, the wall of said combustion chamber adapted for the percolation of fuel o l therethrou'g'h, means for supplying fuel oil thereto. i
T. In a hydrocarbon burner, a hollow combustion chamber in the interior of which combustion takes place, the wall of which chamber is formed of porous refractory material and has longitudinallyextending, interiorly projecting radial fins formed of a similar material, a fuel oil container from which fuel is adapted to pass to the porous wall of said combustion chamber.
8. In a hydrocarbon burner, a hollow combustion chamber provided with a porous refractory wall having interiorly projecting fins, said wall so constructed that fuel oil may percolate therethrough, means for supplying fuel Oil to the wall of said combustion chamber, means for rojecting a steam jet into saidvcombustion c amber, a steam super-heaterfrom which steam is furnished to said jet projecting means, said super-heater so positioned as to be heated from said combustion chamber.
9. In a fuel oil burner, a hollow cylindrical combustion chamber open at one end for the discharge of products of combustion and having a wall formed of a porous refractory material adapted for, the ercolation of liquid fuel therethrough, whic 1 wall is provided with inwardly rojecting'fins of similar material, means or projecting a steam jet into said combustion chamber at the end opposite the discharge opening.
10. Ina fuel oil burner,.,a hollow porous interiorly ribbed combustion, chamber through the wall ofwhich fuel may percolate, and open at one end. for the dlscharge of products of combustion, means for bringing fuel oil to said combustion chamber wall to percolate therethrough, means for projecting a regulated steam jet intosaid combustion chamber at thelend opposite the discharge end, and means for superheatin said steam before itiis projected into sai ('OmbHSlJlOII chamber.
11. In a fuel oil burner, a hollow porous combustion chamber adapted for the percolation of oil through the wall thereof to be burned on the interior and being open at one end for the discharge of the products of combustion, means for supplying fuel oil thereto, a vapor expansion chamber positioned at the end opposite the discharge end and communicating therewith and means for projecting a vapor jet into said expansion chamber.
12. In a fuel oil burner, in combination, a hollow combustion chamber in the interior of which combustion takes place, and which is open for the discharge of products of combustion, an expansion chamber positioned so as to discharge into said combustion chamber, said expansion chamber provided with atmospheric openings.
13. In a fuel oil burner, in combination, a hollow combustion chamber having a porous refractory Wall through Which fuel oil may percolate to be burned on the interior thereof, said combustion chamber open at one end for the discharge of products of combustion and provided at the opposite end with an expansion chamber discharging thereinto, vapor projecting means positioned so as to project a vapor jet into said ex-- pansion chamber, said expansion chamber provided with atmospheric openings about said vapor projecting means.
14. In a hydrocarbon burner, a hollow combustion chamber in the interior of which combustion takes place, said combustion chamber open at one end for the discharge of the products of combustion and having at the opposite end an expansion chamber discharglng thereinto, said expansion cham-- ber provided with air-inlet openings, vapor jet projecting means adapted to discharge into said expansion chamber.
15. In a fuel oil burner, a combustion chamber having an open mouth for discharging products of combustion, a vapor jet producing means positioned so that vapor therefrom may enter the opposite end of said combustion chamber, an expansion chamber intermediate said jet producing means and the combustion chamber so that vapor from the jet will pass through the expansion chamber before entering into the combustion chamber, said expansion chamber provided with atmospheric openings.
16. In a fuel oil burner, in combination, a hollow porous refractory core through which fuel oil may percolate to be burned in the interior thereof, a casing for such core, a steam superheater integral with said casing and adapted to be heated by the products of combustion as they escape from the combustion chamber, an expansion chamber positioned so as to discharge into said combustion chamber, a steam nozzle positioned so as to discharge into said expansion chamber, steam communicating means leading from said superheater to said nozzle.
17 In a fuel oil burner, in combination, a hollow combustion chamber open for the discharge of products of combustion, an expansion chamber positioned so as to discharge into said combustion chamber, vapor jet projecting means positioned so as to discharge into said expansion chamber, said expansion chamber provided with air inlet openings, said combustion chamber provided with auxiliary atmospheric openings.
In testimony whereof, I sign this specification.
