TTORNEY FLAME IGNITER FOR GAS TURBINE COMBUSTOR Robert G. Van Wie, Fullerton, Calif., and Jacob B.

8 Claims. (Cl. 6039.82)
This invention relates to a flame igniter for a gas turbine engine, and more particularly to a flame igniter which is capable of serving more than a single combustion chamber.
In conventional gas turbine design, it has been the practice to provide each combustion chamber with a separate igniter, or to provide an igniter in one or more chambers and then have communication between the various chambers whereby the flame may be carried to the other chambers. Both of these systems have inherent difliculties. To provide a separate igniter in each chamber requires a corresponding increase in initial and maintenance costs, and the use of igniters in only one or more chambers, but not in all of them, may prove unreliable in operation. The igniter of the present invention is specifically designed to overcome difiicuties inherent in prior art devices. It is designed so that a high grade fuel, which is easy to ignite, may be used in the igniter to initiate combustion of a relatively lower grade fuel, which is more diflicult to ignite, in the combustion chamber. Also, it is designed to communicate directly with all of the combustion chambers that it serves so that it will be reliable in operation; and it has novel means to sustain the flames as they are communicated from the igniter to the combustion chambers.
Accordingly, it is an object of this invention to provide an igniter for a gas turbine which is capable of serving a plurality of combustion chambers.
A further object is to provide such an igniter which communicates directly with the combustion chambers which it serves.
A still further object is to provide means to sustain the igniting flames as they pass from the igniter to the combustion chambers.
Briefly stated, in accordance with one aspect of this invention, an igniter cylinder is mounted within an air plenum chamber which also contains a plurality of combustion chambers defined by suitable liners. The igniter cylinder contains apparatus for initiating a flame, and has associated with it a multiple T connection and a plurality of flame feeding tubes to carry flames from the igniter cylinder to the combustion spaces. Tangential holes are provided in the flame feeding tubes to revitalize the flames by admitting additional air to them as they are carried to the combustion chambers.
While it is not intended that this invention be limited to the specific embodiments shown, a better understanding of the device may be had by reference to the following drawings, in which:
Fig. l is a side view, partly in section, of a combustion apparatus with a flame igniter in accordance with the present invention;
Fig. 2 is an end view of the combustion chamber assembly of Fig. l
Fig. 3 is a side view of one of the flame feeding tubes used with the igniter; and
Fig. 4 is a sectional view of Fig. 3, taken along the line 4-4.
2,958,19e Patented Nov. 1, 1960 chamber are a plurality of combustion chambers, de-
fined by cylindrical liners 3. These combustion chambers are conventionally mounted symmetrically Within the plenum chamber as shown in Fig. 2, but such symmetrical mounting is not essential to this invention. A fuel nozzle 4 is mounted in the end dome 5 of each combustion chamber. Any conventional type of fuel nozzle may be used to supply the main fuel to the combustion chambers, and any suitable type of end dome and liner wall construction may be used for admitting primary and secondary air to the combustion chambers. While four combustion chambers have been shown in the drawings, it is to be understood that more or fewer of them could be used without departing from the spirit and scope of this invention.
Centrally located within the plenum chamber is igniter cylinder 6 which is removably mounted to the end dome 1a of the air plenum chamber at 7 by any suitable means. The igniter cylinder has a plurality of holes 8 near its fixed end to admit air to the igniter cylinder from the air plenum chamber. Mounted within the igniter cylinder 6 is a fuel nozzle 9 which extends axially through the igniter cylinder. A suitable spark producing means such as a spark plug or a glow plug 10, also is mounted in the igniter cylinder and extends axially therethrough. Swirler vanes 11 are mounted in the igniter cylinder between the air holes 8 which admit air to the igniter cylinder and the end of the fuel nozzle 9, so that the air which enters the igniter cylinder through holes 8 will be given a strong swirl before the fuel from the fuel nozzle 9 is introduced to it. At the outlet end of the igniter cylinder 6 is a contracting conical nozzle portion 12 terminating in a slip joint 13.
To provide communication between the igniter cylinder 6 and the combustion chambers 3, a special multiple T connection .14 is employed. The T connection is connected to slip joint 13 by means of a conduit 15. The slip joint 13 permits the igniter cylinder 6 to be removed from the plenum chamber, leaving the multiple T connection in place, and is also arranged to admit additional air to the burning mixture as it passes through the slip joint. This is conveniently accomplished by providing adequate clearances 13a in the slip joint to permit the passage of air. The multiple T connection has a plurality of outwardly extending portions 16, corresponding to the number of combustion chambers employed. The outwardly extending portions 16 receive the flame feeding tube 17. The tubes 17 communicate from the multiple T connection to the combustion chambers, the tubes 17 entering the combustion chambers through holes 18 in the liners 3.
Figs. 3 and 4 are enlarged views of the flame feeding tubes 17, which communicate between the multiple T connection 14 and the combustion chamber liners 3. These tubes 17 contain a plurality of holes 19 which admit additional air to the burning mixture as it is conducted through the tubes to the combustion chambers for the purpose of revitalizing and augmenting the flames as the burning mixture is carried from the multiple T connection to the combustion chambers.
In order to avoid directing cold air toward the central core of the burning gases in the tubes, with a resultant tendency to extinguish the flame, the holes 19, as best shown in Fig. 4, are drilled tangentially of the surface of the tubes. This tangential arrangement of the holes also has the effect of revitalizing and augmenting the flame and of re -establishing its vortex swirl. It will be appreciated by those familiar with fluid flow that a vortex is an exceedingly stable type of flow. Therefore, the tangential nozzles 19 tend to smooth out and make uniform the turbulent flow resulting from the subdivision of the main stream of burning gases into a number of separate flows through the respective flame feeding tubes 17 This facilitates the further combustion of unburned fuel due to the injection of the additional combustion air through the nozzles 19. Thus it will be seen that thenozzles 19 perform the functions of supplying additional oxygen, smoothing out any turbulence which may be present resulting from the subdivision of the vortex flow from the igniter 6 into the separate branch passages 16, and creating a smooth uniform vortex flow from the tubes 17 into the respective combustion liners 3.
The operation of the igniter is as follows. Air is introduced to the igniter cylinder 6 through holes s, and as it passes axially down the igniter cylinder, it is given a strong tangential vortex swirl by swirler 11 just before fuel is sprayed into the swirling air by fuel nozzle 9. The amount of fuel introduced by the nozzle 9 is controlled so that an over-rich mixture is formed at that point. This mixture is ignited by the sparkproducing means 10*, and the swirling mixture of burning gases then passes down the contracting conical nozzle portion 12, through the slip joint 13, where additional air is introduced through the clearances 13a, and into the multiple T connection 14. When the vortex swirl of burning gases reaches the multiple T, it is divided into a number of separate streams of burning gas, one of which enters each of the tubes 17.
Each of these separate streams of burning gas necessarily has to turn, 90 in the arrangement shown here, to be directed toward the various combustion chambers through the flame tubes, and this action tends to quench the flame. In order to revitalize and augment the flames before they are introduced into the combustion chambers, the tangential additional air holes 19 are provided. When the burning mixture passes the holes 19, additional air is introduced to the mixture from the plenum chamber through these holes. Since the fuel-air ratio was over-ric in the igniter cylinder, there is still sufficient unburned fuel in the mixture as it passes the holes 19. The air introduced into the tubes through the tangential holes combines with the unburned fuel and thus tends to revitalize the flames. Since the air is introduced tangentially, it has no objectionable tendency to extinguish the flames, and it also has the effect of reestablishing the stable vortex swirl as discussed above.
When the burning mixture, which has been revitalized by the additional air from the holes 19, enters the combustion chambers, a combustible mixture exists in the combustion chambers because fuel will have been intro duced there through the fuel nozzles 4. This combustible mixture is ignited by the flame from the flame igniter, thus starting the combustion process in the main combustion chambers of the turbine. Generally a highgrade volatile fuel, such as kerosene or diesel fuel is introduced into the igniter 6 at its nozzle 9, because such fuel is relatively easy to ignite; and relatively lower grade fuel, for instance a heavy residual fuel oil, such as that known to the trade as Bunker C, is normally used to operate the turbine. Thus the advantage of using fuel which is relatively easy to ignite for starting is derived, and at the same time the turbine can operate normally on the lower grade fuel.
While particular embodiments of this invention have been shown and described, further modifications will appear tothose skilled in the art. It is to be understood therefore that this invention is not to be limited to the specific embodiments shown, and it is intended that the appended claims cover all such modifications as fall within the true spirit and scope of the invention.
