    • A gas turbine combustor (10) comprises a base plate (12) from which protrude a plurality of lips (36) that surround respective apertures (16) into which are positioned downstream ends (19) of main swirler assemblies (18). The apertures (16) are arranged about a centrally positioned pilot cone (22) that comprises an inner cone (23) and an outer cone (25), defining a space (31) there between. A number of laterally directed apertures (60) are disposed along the outer cone (25) so as to direct a flow of fluid toward a near portion (38) of each lip (36), thereby perturbing pockets of high fuel-to-air mixtures between the outer cone (25) and the near region (38). The provision of such laterally directed apertures (60) reduces or eliminates flashback between the outer cone (25) and the near region (38) through such action.

    • The invention concerns an arrangement of burners for a heating installation, in particular a gas turbine combustion chamber, comprising a main burner (1) and a pilot flame for lighting and/or stabilising the main burner (1). Said pilot flame is permanently or temporarily used as premix burner, and a supply system (6, 7, 8, 9) in the form of a pipe for supplying fuel and combustion air, said system including at least an air duct (6) with a more or less circular cross-section, and which is provided with intakes (10; 11) for the fuel. In the direction of the air flow upstream of said intakes (10; 11) which are arranged preferably at regular intervals on the periphery of the air duct (6), a vortex generator (12) is provided in the air duct (6). The latter acts as diffuser (13) at its end zone emerging into the heating installation and with in particular an end zone (13) ever widening in cross-section and also capable of being cooled. The vortex generator (12) upstream of the fuel intakes (10; 11) ensures stable and safe functioning of the pilot flame with slight production of NOx.

    • A combustor with a flashback arresting system for producing a hot gas by burning premixed fuel and compressed air having fuel/air premixing passages, each of the passages having an inlet end and a discharge end. Disposed immediately upstream of the inlet ends of the fuel/air premixing passages is a fuel manifold for delivering fuel to the passages. Fuel lines with fuel flow control valves connect the fuel manifold with a fuel supply. The flashback arresting system has one or more optical flame detectors with a light receiving portion located upstream of the discharge ends of the fuel/air premixing passages and oriented toward at least a portion of at least one of the fuel/air passages. The flame detectors are responsive to receiving light from a flashback by its light receiving portion by transmitting an output signal to a control system. The control system controls the fuel flow control valves and responds to the output signal by adjusting the fuel flow control valves to eliminate the flashback.
    • 一种燃烧器,其具有用于通过燃烧具有燃料/空气预混合通道的预混合燃料和压缩空气来产生热气体的回火制动系统,每个通道具有入口端和排出端。 在燃料/空气预混合通道的入口端的紧上游的上方设置有用于将燃料输送到通道的燃料歧管。 具有燃料流量控制阀的燃油管路将燃料歧管与燃料供应连接。 回闪阻止系统具有一个或多个光学火焰检测器,其中光接收部分位于燃料/空气预混合通道的排放端的上游,并且朝向至少一个燃料/空气通道的至少一部分。 火焰检测器通过将输出信号发送到控制系统来响应于通过其光接收部分从闪回接收光。 控制系统控制燃料流量控制阀并通过调节燃料流量控制阀来响应输出信号以消除回火。
