Patented Apr. 11, 1950 HEATER' Joe Wilbur Beggs, McPherson, Kans., assignor to Black, Sivalls & Bryson, Inc., Kansas City, Mo., a corporation of Delaware ApplicatonAugust 13, 1945, Serial No. 610,549

This invention relates to heaters, particularly adapted for using a crude oil or the like for fuel, for example, fluid jacket heaters such as used in treating hydrocarbon liquids.

In heaters of this character, gas and liquid fuels that operate satisfactorily in conventional burner equipment are not always available and it is desirable to use a portion of the liquid being treated in the heater for fuel.

It is, therefore, the principal object of the invention to provide a burner equipment for a fluid jacket heater capable of operating satisfactorily on a portion of the readily available hydrocarbon oil.

Other objects of the invention are to provide a simple and inexpensive burner for fluid jacket heaters and to provide a burner capable of operating over a substantial period of time with a minimum of attention and regulation.

In accomplishing these and other objects of the invention I have provided improved structure, the preferred form of which is illustrated in the accompanying drawings wherein:

Fig. 1 is a perspective view of a iiuid jacket lheater designed and equipped with a burner mechanism embodying the features of the present invention.

Fig. 2 is a vertical section through the fluid jacket heater.

Fig. 3 is a perspective view of the burner pan, air admission duct and flange coupling therefor shown in disassembled spaced relation.

Fig. 4 is an elevational section through the sight tube.

Referring more in detail to the drawings:

I designates a substantially conventional duid jacket heater which in the illustrated instance includes an outer jacket 2 comprising a cylindrical `wall 3 closed at the upper end by a head 4 and at the lower end by a base plate 5 of larger circumference than the wall to provide a projecting footing flange 6. Enclosed in the jacket is a heating unit l including an annular wall 8 spaced from the wall 3 of the jacket to form an annular fluid passageway 9 therebetween and an inner heating chamber. The wall 8 is of less height than the wall 3 to provide an upper uid circu lating space I encircling a ue outlet I I, the outlet being formed by a collar I2 encircling an opening lI3 in a head I4 that connects with the wall 8. The lower end of the `wall 8 is connected by a circumferential flange I with the wall of the outer jacket at a point spaced above the base plate 5.

Formed Yin the Side wall of the outer jacket in 1 Claim. (Cl. 122-17) iro substantial registry with the -space I6 above the b-ase plate is a door I'I through which access may be had to a burner space within the heating unit. The door I'I is retained in position by suitable clamping devices I8 to provide an air-tight closure so that the air supply to the burner is under control.

Fluid to be heated is admitted to the lower end of the passageway 9 through a pipe I9 and discharged from the upper end through a pipe 20 Ias shown in Fig. 1. As above stated, it is often desirable to heat the fuel being treated with the most available fuel such as the liquid hydrocarbon being treated, consequently, a special burner assembly is required to burn such fuel as now to be described: j A

The burner assembly includes a burner pan '2I preferably formed of cast iron orfother heat resistant material and includes a bottom 2.2 having an annular wall 23, the bottom 22 being supported above the base plate upon nre brick 24 as shown in Fig. 2. The` burner pan is adapted for insertion through the door I'I and is of smaller diameter than the wall 8 so that the flange of the pan is adapted to project partially into the lower end of the heater.l Extending through the outer jacket and the wall of the heater at a point above the base plate is a tube 25 suitably connected thereto to provide leak-tight connectionv and form an entrance opening through the jacket to the interior of the heater unit. The tube25pro jects from the jacket and `carries an annular flange 26 for attaching a collar 21 forming fan inlet 28 for combustion supporting air. vThe colf lar 21 carries a flange` 2 9V that is removably'connected with the flange 26 by fastening devices30. Connected to the collar in any suitable manner is a pipe 3| leading over the pan 2| toward the center thereof and which carries an elbow 32 having a downwardly extending discharge nipple 33 located substantially over the burner pan and pro- 'jecting slightly thereinto `as shown in Fig. 2. The pipe 3|, elbow 32 and nipple 33 thus provide an air flow duct through which all of the air necessary to support combustion is admitted into the heater unit and directed downwardly for discharge into the burner pan.

Fuel is removed from the passageway at the top of the heater jacket by a pipe 3l! which is connected through a union 35 with a pipe 36 having a control valve 31 therein. The pipe 36 leads substantially horizontally through the air supply duct and is supported within the respective ends of the pipe 3| by spiders 38 and 39. The terminal end of the pipe 36 carries an L fitting 40 having depending nipple 4l which discharges downwardly coaxially `of the nipple 33 forming a discharge nozzle coaxial with the air stream. Hot products of combustion resulting from the burner rise upwardly of the walls of the heater to heat the walls for transmitting heat to the liquid being circulated through the passageway, the products of combustion being nally discharged through the ue outlet I I.

The air ow through the air supply duct is maintained responsive to the draft effected by burning of the fuel and expansion of the hot products of combustion through the ue outlet.

In order to observe action of the burner, a peephole is provided into the burner space. This is effected through a tube 42 arranged slantwise and extending through

suitable openings

43 and 44 in the

walls

3 and 8. The outer end of the tube projects from the outer jacket and carries a cap 45 (Fig. 4) having a heat resistant transparent .closure 46 which may be formed of Pyrex or other borosilicate glass. The tube is arranged at such an angle that the burner pan and nozzle are readily sighted therethrough.

In operation, fuel is admitted under control of the valve 31 and discharged into the burner pan 2| coaxially of an air stream moving through the air inlet duct responsive to draft through the flue outlet Il. Upon ignition the fuel heats the pan to substantially red heat and the flames pass upwardly along the inner sides of the heater chamber to heat the surrounding uid. Action of the flames and operation of the burner is readily discernible through the transparent window of the sight tube.

An apparatus constructed and assembled as described is capable of operating over a substantial period without coking up of the burner pan or clogging of the burner nozzles. While the burner is operated at substantially high temperature, the air duct and fuel supply line remains comparatively cool by reason of the cooling effect of the air which supports combustion, consequently, the parts of the burner will not burn out readily, particularly when constructed of cast iron or other heat resistant material.

From the foregoing it is obvious that I have provided a heater structure especially adapted for fluid jacket heaters which is of simple and inexpensive construction and capable of successful operation on readily available fuels such as crude oil and the like and without the necessity of the conventional expensive fuel controls.

What I claim and desire to secure by Letters Patent is:

A heater for liquids including outer and inner jacket above the bottom of the outer jacket and provide a space conforming to depth of the fuel pan, said wall of the outer jacket having a fuel pan insert opening below said ring for insertion of the fuel pan under said ring, means for supporting the fuel pan in raised position after it has been inserted, a tube extending through the walls of the jacket at a point above the pan and having a flange exteriorly of the outer jacket, an air supply duct extending coaxially through said tube and terminating within the inner jacket .in a downwardly directed outlet end discharging substantially coaxially within the fuel pan and having a flange on the outer end abutting the flange on said tube, fastening means for securing the flanges together to support the air supply duct in fixed relation with respect to the axis of the pan, a fuel supply pipe extending through the air duct and terminating in a downwardly directed fuel outlet for discharging fuel into the pan, and means supporting the fuel supply pipe with said downwardly directed terminal in coaxial relation with the discharge end of the air supply duct.
