Description
April 1953 R. G. MESCHINO ANNULAR VAPORIZER Filed June 15, 1950 E ad @06 /v Patented Apr. 21, 195i? UNITED STATES PATENT OFFICE 2,635,426 ANNULAR VAPORIZER Ronald Guerin Meschino, Toronto, Ontario, Canada, assignor to A. V. Roe Canada Limited, Malton, Ontario, Canada, a corporation Application June 15, 1950, Serial No. 168,294 In Great Britain June 29, 1949 3 Claims.
as atomizing burners and vapourizing elements of various forms. This invention is applicable to the vapourizer type of installation and particularly to that construction, hereinafter referred to as the wall-type vapourizer, described in my co-pending application Serial No. 145,060 dated February 18,1950.
' The aforesaid application describes a combustion system embodying a combustion chamber through which a stream of air is constrained to flow, a flame tube having open ends to receive part of the air and disposed substantially coaxially within the combustion chamber, means for introducing fuel into the flame tube and ignition means for initiating combustion within the flame tube; the vapourizing system in this construction comprises an annular vapourizing element forming an integral part of the flame tube wall and extending downstream substantially from the upstream end of the flame tube, an inlet in. the vapourizing element for directing a portion of the air entering the flame tube into the upstream end of the said element, the means for introducing fuel being adapted to direct the fuel into the vapourizing element, and means for reversing the flow of the said portion of the air stream and the fuel as they emerge from the downstream end of the vapourizing element into the flame tube, whereby the air and fuel emerging from the said element are directed substantially upstream. Moreover the preferred means for introducing fuel includes a plurality of jets situated within and adjacent to the upstream end of the vapourizing element.
In order to prevent overheating of the vapourizing element and to obtain good vapourization of the liquid fuel before it emerges into the flame tube, it is important that the fuel should be uniformly distributed over the vapourizing surface. In the application of an annular wall-type vapourizer to an annular combustion chamber, this distribution can be achieved by locating the element on the radially inner wall of the flame tube (1. e. on the wall closer to the axis of the combus- 2 tion chamber), spacing the jets symmetrically around the vapourizer intake and directing them so that they will all spray in a direction having a tangential component and in the same sense. Furthermore, in this construction, distribution of the fuel can be improved by the provision of swirl vanes situated up-stream of the jets in the inlet of the vapourizing element to give the air entering the vapourizer a rotation in the same sense as the tangential sprays from the fuel jets, so that the fuel tends to be carried onto the vapourizin surface by centrifugal action. 7
/ If, however, an annular wall-type vapourizer is mounted on the outer wall of the flame tube of an annular combustion chamber or if such a vapourizer is applied to a tube-type combustion chamber, any centrifugal forces acting upon the air and fuel in the element will tend to carry the fuel away from the vapourizing surface, which may result in overheating and consequent failure of the vapourizer. Thus in such circumstances the swirl vanes cannot be utilized and every precaution'must be taken to avoid rotation of the fuel and air mixture.
It is the main object of this invention to ensure the uniform distribution of fuel over the vapourizing surfaces of annular wall-type vapourizers, where the application of centrifugal forces to the fuel and air in the vapourizer may tend to impair the cooling of the vapourizing surface.
Other objects and advantages of the invention will be apparent from the following description of an application thereof to a tube-type combustion chamber.
In the accompanying drawing forming a part of this application and in which like reference characters designate like parts throughout the several views:
Fig. 1 is a side elevation of an engine having a tube-type combustion system, one combustion chamber being shown in section;
Fig. 2 is a section of the upstream portion of a combustion chamber, showing the flame tube and wall-type vapourizer; and
Fig. 3 is a section on the line 3-3 in Fig. 2, to an enlarged scale.
Air is drawn into the engine illustrated in Fig. 1 by the compressor l0 and is discharged through diffusers ll into combustion chambers i2. Fuel is introduced through a fuel line [3 to each combustion chamber l2 and burned in a flame tube 14 lining the combustion chamber. From the flame tube the products of combustion are discharged into turbine I5. In the particular engine illustrated the turbine serves only to drive the compressor and engine auxiliaries, the exhaust from the turbine emerging from tail cone I6 to provide a propulsive thrust.
The combustion chamber arrangement and in particular the vapourizer which is the subject of this invention is illustrated in greater detail in Fig. 2. The casing of the combustion chamber I2 is attached to the diffuser II, and the flame tube I4 is supported within the casing and spaced therefrom by two interconnectors I'I (only one of which is shown in Fig. 2) and by a conventional additional support (not shown) to provide three mounting points; the interconnectors I! extend through the walls of the flame tube to enter the flame zone as indicated. The interconnectors, as will be known to those skilled in the art, are balance pipes provided to interconnect the flame zones of adjacent combustion chambers, and at least one of them houses a torch igniter II and an igniting spark plug Il The wall-type vapourizer is formed by the inner vapourizing shell I8 which is situated within the flame tube It and is substantially uniformly spaced from the wall thereof. The shell I8 extends downstream substantially from the upstream end of the flame tube, adjacent the diffuser II, to provide an annular vapourizer generally indicated by the reference numeral I9 terminating in an annular mixing chamber 20; the downstream end of the shell I8 providing the mixing chamber 20 is constituted by a frustoconical wall 2| having a cylindrical extension 2| which is secured tothe flame tube I4 by a radial flange 2I A number of holes 22, facing upstream, are provided in the wall 2| of the shell I8. A perforated plate 23 is provided at the upstream end of the flame zone, spanning the inner shell IB and effectively closing the flame tube to the direct entry of, air from the diffuser, other than through the perforations in the plate. The plate is preferably slightly concave with respeet to the entering air and the perforations are arranged symmetrically near its periphery. so that a central region of low pressure is induced in the air stream immediately downstream of the plate.
Fuel is introduced to the annulus I9 constituted by the space between the shell and the wall of the flame tube, by means of a series of jets 24 fed from the central supply line I3 and symmetrically disposed in a circle at the upstream end of the annulus I9. These jets are arranged to direct sprays of fuel. into the upstream end of the annulus to impinge upon, the. radially outer surface of the vapourizing shell I8. Radially disposed partitions 25 are angularly spaced around the axis of the flame tube between adjacent jets 24 and extend longitudinally downstream between the flame tube I4 and the shell I8 dividing the annular vapourizer I9 into a plurality of sections I9, each being a sector of the annulus constituting the vapourizer; each jet discharges into one such section of the vapourizer and the fuel therefrom is confined to its particular section until it has travelled to the mix-. ing chamber 20. The partitions 25 are preferably rigidly mounted on the vapourizer shell I8 and spaced from the flame tube I4 so that a small expansion clearance is provided between their outer edges and the inner surface of the flame tube wall; in effect they then constitute radial fins disposed on the vapourizer shell.
In operation air from the compressor I passes through the diffuser II into the combustion chamber I2. The greater portion of the air is directed into the usual annular space between the combustion chamber and the flame tube I4, to provide a cooling jacket and to enter the flame tube in its lower stages as a cooling film along the walls or as diluent air, in the usual manner. The remainder enters the flame tube I4 at its upstream end and a part is directed into the vapourizer I9, while the rest flows through the perforations in the plate 23. Fuel introduced by the jets 24 is mixed with the air in the vapourizer, forming a combustible mixture which is discharged from the mixing chamber 20 through the holes 22. By virtue of the depression induced immediately downstream of the plate 23, the air entering the perforations in the said plate will turn inwardly, as indicated by the arrows, A in Fig. 2, and will be thoroughly mixed with the discharge of the vapourizer. Combustion may be then initiated by the torch igniter I1 situated in one of the interconnectors I1, which protrude into this region of stability.
Once lighted, combustion is self-propagating and the mixture discharged from the vapourizer is ignited as it enters the flame zone bounded by the plate 23 and the shell I8 of the vapourizing element. The heat of combustion acting upon the said shell promotes rapid and complete vapourization of the liquid fuel flowing over the outer surface of the shell and, in turn, the vapourization cools the shell against overheatmg.
It will be understood that overheating of the vapourizing surface is likely to occur if the fuel is not distributed uniformly thereupon. It is important therefore that the diameter of the vapourizing surface should not decrease and preferably should increase progressively along the vapourizer, and they gravitational forces acting upon the fuel should not be allowed to divert the flow to the lower portions of the annulus. It is for the latter reason that the partitions 25 are provided since they divide the vapourizer into separate sections, thereby preventing the fuel from flowing to the lower portions, and effectively eliminating any swirl in the mixing air which might induce centrifugal forces.
Although an application of the invention to a tube-type combustion chamber has been described herein, partitions similar to the partitions 25 can be applied with equal effect to combustion systems of the annular type, particularly when the wall-type vapourizer is installed on the outer wall of the annular flame tube. It will be understood therefore that various changes in the shape, size and arrangement of the parts of the construction may be resorted to without departing from the scope of the claims.
