Abstract
1,064,609. Gas turbine plant. ROLLSROYCE Ltd. Oct. 18, 1965, No. 44102/65. Heading F1G. A power plant comprises at least one gas turbine type gas generator, a plenum chamber arranged to receive the combustion gases from the or each gas generator and which has a plurality of outlets through which the combustion gases may be discharged, a free power turbine being mounted in each outlet, there being control means responsive to changes in the rotational speeds of the free power turbines, for effecting adjustment of the fuel supply to the gas generator or gas generators the control means comprising outlet area adjustment devices for altering the effective areas of the respective outlets so as to adjust the rotational speeds of the respective free power turbines, the outlet area adjustment devices being interconnected so that an effective increase or decrease in one said area is respectively accompanied by an effective decrease or increase in the other said area or areas, whereby the total effective area of all the outlets, prior to the said adjustment of the fuel supply, is maintained substantially constant. In Fig. 1 two gas turbine type gas generators 11 are provided, the gas generators supplying combustion gases to a common plenum chamber 12. Each gas generator has a fuel control unit 21 through which fuel is supplied to the injector 20 in the combustion equipment 15, the two control units being connected to a device 55. Four outlets 23 are provided from the plenum chamber 12 a free power turbine 24 and adjustable inlet nozzle guide vanes 25 being provided in each outlet 23, each free power turbine having associated therewith a governor 26. The four governors 26 are operatively interconnected to the sets of nozzle guide vanes 25 and to the device 55 as indicated in Fig. 2 (not shown) by a system of springs and levers, so that if in operation the load on one of the free power turbines 24 should increase, the rotational speed thereof will fall. The governor 26 associated with that turbine will therefore exert on the spring 30 associated therewith a force which will tend to move the associated nozzle guide vanes 25 in a direction such as to increase the area of the respective outlet 23. This force will not however be fully transmitted to the nozzle guide vanes 25 since it will be resisted by the springs 30 of the remaining free power turbines. Thus if the governor 26 of the underpowered free turbine 24 is attempting to move its nozzle guide vanes 25 so as to achieve a 20% increase in the area of its outlet 23, it will in fact achieve an increase of area of the said outlet of 15% and this will be accompanied by a reduction in the areas of the outlets 23 by 5% in each case, so that the total effective area of the four outlets 23 will at this stage be maintained substantially constant. The contacts 52, 53 will be brought out of contact with each other since all the free power turbines 24 will be temporarily underpowered, so that the device 55 will send signals to the fuel control units 21 as a result of which more fuel will be supplied to the gas generators 11 so that the rotational speeds of all the free power turbines 24 will be brought to the individually selected values. At the same time, the nozzle guide vanes 25 of the various free power turbines 24 will be adjusted so as to effect appropriate increase in the total area of the outlets 23.
