Attorney-Clelle W. Upchurch ABSTRACT: A burner assembly for the combustion of crude oil such as often escapes from offshore wells. The assembly includes means for breaking the oil into small droplets to facilitate the combustion thereof and structure adjacent the discharge ports for preserving ignition of the burning oil. A supply of air serves to direct the flame and the heat of combustion away from the apparatus and personnel. The assembly includes structure which develops a screen of water for the absorption of heat and the protection of the burner assembly and other elements located upstream of the combustion zone.
FIG.
SHEET 1 [IF 2 h 4 1 j v Q E Q W ll] Ill INVENTOl-PS' F ATTORNEY BURNER ASSEMBLY FOR COMBUSTION OF OIL The present invention relates to a burner and equipment for the combustion of crude oil and the invention more specifically pertains to a burner assembly which is capable of burning such liquids at the rate of as many as 6,000 barrels per day and at a rate which develops as much as a billion six hundred thousand British Thermal Units per hour.
In the course of drilling and testing of offshore wells, there are occasions when crude oil is spilled onto the water. The oil floating on the water is undesirable and it is an object of the present invention to provide a burner assembly which is capable of the combustion of crude oil and at rates of as much as 6,000 barrels per day with the combustion taking place in the atmosphere and to thereby reduce the quantity of oil that may spread over the surface of the sea or water.
Another object of the invention is to provide a burner assembly wherein crude oil is broken into small droplets and released for burning with the burner assembly equipped with means for maintaining ignition of the burning fuel.
A still further object of the invention is to provide means for directing a current of air over the burner so as to cause the flame to move downstream with the current of air and thus provide a structure which is capable of directing the heat developed by the combustion away from a drilling rig or platform and with the air-developing turbulence in the burning fuel to accelerate the rate of burning of the oil.
Another and further object of the invention is to provide apparatus which serves to develop a screen of water immediately upstream of the burner head to provide for the absorption of heat and the protection of equipment and personnel upstream of the combustion zone.
Other objects and features of the invention will be appreciated and become apparent to those skilled in the art to which the invention pertains as the present disclosure proceeds and upon consideration of the following detailed description taken in conjunction with the annexed drawings wherein an exemplary embodiment of the invention is disclosed.
In the drawings:
FIG. I is a side elevational view of a burner assembly embodying the invention.
FIG. 2 is a longitudinal sectional view of the burner head.
FIG. 3 is an elevational view of the downstream end of the burner head.
FIG. 4 is a longitudinal sectional view of the housing which encases the burner head.
FIG. 5 is an end elevational view taken on the line 5-5 of FIG. 4.
The invention pertains to apparatus for the combustion of crude oil and includes a structural arrangement for insuring atomization of such oil and the continued kindling of the oil droplets and structure shielding portions of the burner assembly from heat released downstream of the burner head.
Referring to the drawings, there is shown at a housing in which the burner head is mounted. The housing is connected at 11 to a relatively large duct 12. A fan 14 of large capacity and desirably of the centrifugal type is mounted on a suitable base. A motor 16 drives the fan and supplies air into the duct 12 and for movement through the housing 10. A discshaped baffle 17 (FIGS. 4 and 5) is mounted in the housing 10 and supported by a plurality of radially disposed arms 18. The baffle 17 shields the upstream end of the burner head 15 from the current of air moving through the housing 10.
The burner head 15 is best shown in FIG. 2 and includes a relatively thick disc-shaped plate 21 which forms the downstream end of the burner head. A tubular member 22 joins the plate 21 adjacent the periphery thereof and is desirably welded thereto. The upstream end of the tubular member 22 is closed by an annular plate 23. A conduit fitting 26 is provided for admitting a gaseous atomizing medium into the burner head 15 and into the tubular member 22. A sleeve 27 embraces the forward portion of the tubular member 22 nndjoins the peripheral portion of the plate 2 l. The upstream end portion of the sleeve 27 joins the perimeter of the tubular member 22 as indicated at 28. The sleeve 27 is of greater diameter than the tubular member 22 and an annular space 29 is provided around the periphery of the tubular member 22. A conduit fitting 31 mounted on the sleeve 27 is for the purpose of admitting crude oil to the annular space 29.
A plurality of ports 33 are formed in the plate 21 through which the gaseous atomizing medium may escape. These ports 33 have their axes aligned with the axes of discharge openings 34. The openings 34 are of larger diameter than the ports 33. Apertures 36 which are equal in number to the discharge openings 34 provide communication between the annular 'space 29 and the discharge openings 34. The gaseous medium escaping through the openings 34 serves to draw oil from the annular space 29 into the respective discharge openings and to break the crude oil into small droplets and propel it through the openings 34.
A ring 39 may be welded or otherwise secured to the perimeter of the plate 21. A plurality of apertures 41 extend through the ring 39. These openings are circumferentially spaced from each other about the entire ring 39. A plurality of vanes 42 are secured to the periphery of the ring 39. Each of the vanes 42 is of rectangular shape. These vanes are disposed at an angle with respect to the plane of the ring 39. Thus air moving through the housing 10 engages the vanes 42 which impart an angular component to the air adjacent the periphery of the burner head. The apertures 41 and the vanes 42 function to preserve ignition of the atomized oil which escapes through the discharge openings 34.
A manifold 46 surrounds the downstream end portion of the housing 10. A pipe 47 is provided for delivering water under pressure into the manifold 46. A multitude of spray nozzles 48 are mounted on the manifold 46 in communication with the interior thereof. The water escaping through the nozzles 48 provides a screen which absorbs and carries heat away from the combustion zone and thus shields the housing 10 and the equipment upstream of the burner head from the heat developed by the combustion which takes place downstream of the burner head. The water screen makes it possible to locate the fan 14 much closer to the burner head without heat damage. The heat released during the combustion of 250 barrels of crude oil per hour is in the range of l'wbillion British Thermal Units per hour so that the water screen developed by the nozzles 48 becomes an important part of the equipment. The air forced through the housing 10 is at a rate of about feet per second and serves to force the flame in a direction downstream from the burner head 15. Thus the flame may be forced to move away from an offshore platform or the like.
A number of pilots may be mounted within the housing 10 and in spaced relationship about the downstream end of the burner head. Crude oil is delivered through a pipe 52 which supplies the oil under pressure into the annular space 29. A gaseous atomizing medium such as natural gas or steam or air is supplied under pressure into a pipe 53 and into the tubular member 22. The gaseous atomizing medium escapes through the ports 33 and develops low-pressure conditions within discharge openings 34 adjacent the apertures 36. The crude oil is thus broken into small droplets and is discharged through the openings 34. Upon ignition the atomized oil burns in a zone downstream of the burner head. The air supplied by the fan 14 moves through the apertures 41 and between the spaced vanes 42 to create turbulence in the burning oil and thereby promote combustion. Water is supplied under pressure into the pipe 47. The water escapes through the nozzle 48 to provide a screen of water vapor about the perimeter of the downstream end portion of the housing 10. The water absorbs heat and shields the equipment positioned upstream of the screen. The heat absorbed by the water is carried from the vicinity of the burner head.
While the invention has been described with reference to particular structural features, it will be appreciated that changes may be made in the overall organization as well as in the components. Such modifications and others may be made without departing from the scope of the invention as set forth in the appended claims.
