摘要： A gas turbine engine control method and apparatus as disclosed for optimizing fuel/air mixture, especially during decreasing load conditions. In a large capacity gas turbine engine system used for generation of electric power, the system is designed to operate at a relatively constant rotational speed of the turbine which drives an electric generator unit. The load of the turbine engine varies throughout the day due to changes in electrical power demands. During normal rated load conditions, the control of the fuel/air mixture is by way of changes in fuel supply, corrected to return the turbine exhaust temperature to a desired rated temperature. During this mode of operation, the compressor inlet guide vanes are maintained in a substantially constant open position. For accommodating decreasing load conditions where the temperature drops below a predetermined temperature level below the rated temperature operation, the system is switched to an inlet guide vane control mode of operation. During the guide vane control mode of operation, the inlet guide vanes are controlled at a more precise temperature correction sensitivity than is the case for normal load operations. This more precise inlet guide vane control during decreasing load conditions assures improved fuel/air mixture during decreasing load and consequent improved efficiency and minimal NO.sub.x compound emissions, especially during changing ambient temperature conditions where cold air would otherwise increase the air supply.
摘要翻译：公开的用于优化燃料/空气混合物的燃气涡轮发动机控制方法和装置，特别是在减小负载条件下。在用于产生电力的大容量燃气涡轮发动机系统中，该系统设计成以驱动发电机单元的涡轮机的相对恒定的转速运行。由于电力需求的变化，涡轮发动机的负载在一整天内变化。在正常的额定负载条件下，燃料/空气混合物的控制是通过燃料供应的变化来进行的，这被校正以将涡轮排气温度恢复到所需的额定温度。在这种操作模式下，压缩机入口导叶保持在基本恒定的打开位置。为了适应温度下降到低于额定温度运行的预定温度水平的降低负载条件，系统被切换到入口导叶控制操作模式。在导叶控制操作模式下，入口导流叶片的控制精度比正常加载操作更为精确。在降低负载条件下，这种更为精确的入口引导叶片控制确保了在减少负载的同时改善了燃料/空气混合物，从而提高了效率和最小化的NOx化合物排放，特别是在其他空气会增加空气供给的环境温度变化的环境中。

摘要： A control method of a gas turbine which is provided with a multi can type combustor consisting of a plurality of unit combustors, each of which has a first stage combustion section for diffusion combustion and a second stage combustion section for premix combustion. Combustion states in the first and second stage combustion sections are monitored to take in quantities representative of the combustion conditions as control factors. The combustion in the second stage combustion section is assumed to be abnormal when the taken in quantities exceed an allowable limit and the combustion in the first and second stage combustion sections is changed to independent combustion only in the first stage combustion section when the number of unit combustors, each of which is assumed to be abnormal, exceeds a predetermined number of the unit combustors.

摘要： A combustor of two-stage combustion type in which fuel is supplied only from primary fuel nozzles for combustion only in primary combustion chamber under the operating condition where gas turbine load is low, and premixed mixture is supplied into a secondary combustion chamber provided on the downstream side of the primary combustion chamber for combustion in both the primary and secondary combustion chambers under the operating condition where the load is high. An air-bleed passageway opens on a downstream side of air holes for intaking secondary combustion air to be mixed with secondary fuel and communicates with the outside of the combustor. The air-bleed passageway is provided with a regulating valve and the secondary combustion air is bled at the minimum point of the load where the secondary fuel is supplied so that the fuel to air ratio of secondary premixed mixture may not be excessively lean, thereby reducing the production of non-burned components.

摘要： A combined gas turbine plant comprises an air compressor, a combustor including a combustion chamber, a gas turbine, a steam turbine, and an exhaust heat recovery device having a denitration device and arranged at a location through which an exhaust gas passage for leading exhaust gas from the gas turbine to the atmosphere extends. An air extraction pipe equipped with a valve is provided for extracting a part of the air from the air compressor to prevent surging of the air compressor during starting of the plant, and another air extraction pipe equipped with a valve is provided for extracting a part of the air from an air passage extending from the compressor to the combustion chamber to improve stability of a flame and combustibility in the combustion chamber during the plant starting. The extraction pipes extend to and hence lead the extracted air into a portion of the exhaust gas passage located downstream of the denitration device.

摘要： A gas turbine combustor has a plurality of burner units each having an inner tube defining a combustion chamber therein and an outer tube surrounding the inner tube coaxially therewith. A fuel is injected into the head portion of the inner tube and is burnt in the combustion chamber to produce hot combustion gases which are guided through a tail tube to stationary blades of a gas turbine. Combustion air is supplied through an annular passage between the inner and outer tubes from the area around the tail tube to the head portion of the inner tube. A flow-uniformalizing tube is disposed between the inner and outer tubes to cooperate with the inner tube to define therebetween an air passage. The flow-uniformalizing tube imparts a greater flow resistance to air flow from the back side of the tail tube than to the air flow from the side thereof diametrically remote from the back side, so that the flow velocity of the air flowing through the air passage is substantially uniformalized in the circumferential direction of the inner tube.

摘要： A method of starting a gas turbine plant, which plant has at least one combustor including a primary combustion chamber into which primary fuel nozzles open and a secondary combustion chamber into which secondary fuel nozzles open, a compressor for supplying the combustor with compressed combustion air, and a gas turbine driven by the combustion gas generated in the combustor and adapted to drive a load such as an electric power generator. When the gas turbine is being accelerated to a rated speed or while the load is still below a normal load range, a fuel is supplied only to the primary fuel nozzle, whereas, in other loaded operation range, the fuel is supplied to both the primary and secondary fuel nozzles. Before the fuel supply to the secondary fuel nozzles is commenced, a part of the compressed air is bled through at least one air bleed pipe leading from the compressor and having an air bleed valve. The air bleed valve is controlled in such a manner that the opening degree thereof is maximized when the fuel supply to the secondary fuel nozzles is commenced and is progressively decreased in accordance with the increase of the load such as to become substantially zero when the load has been increased to the normal load range.
