    • PURPOSE: A fuel staging device for gas turbine nozzle and a method thereof are provided to improve flame holding performance by forcibly supplying fuel, controlling such a work that fuel is divided into a plurality of combustion nozzles with remote operation, selectively supplying fuel to one or more nozzles of the first group in combustors, and closing flow of fuel toward one or more nozzles of the second group in combustors which do not include the nozzle of the first group. CONSTITUTION: In a device wherein outlet ends of a plurality of combustors(10) are connected to inlet ends of a turbine and high temperature combustion gas is supplied to the turbines and each of combustors(10) are provided with a plurality of nozzles(14), fuel is supplied to a manifold(28) to which a plurality of combustor supplying pipe passages(26) are connected in parallel by a main supplying leading pipe (22) and a control valve(24), and a plurality of nozzles(14) are connected to the combustor supplying pipe passage(26). A fuel dividing valve(30) is disposed in the supplying pipe passage(26), a pneumatic device for supplying air from an air supplying source(40) through a staging control valve(44) is arranged on a fuel dividing valve(30), fuel having a prescribed quantity is supplied to the nozzles of the first group by controlling the valve(30) with remote operation, and it is closed that fuel is supplied to the nozzles of the second group.
    • 目的:提供一种用于燃气轮机喷嘴的燃料分段装置及其方法,以通过强制供应燃料来改善火焰保持性能,控制燃料被分成多个具有远程操作的燃烧喷嘴的工作,选择性地将燃料供应给一个或 燃烧器中的第一组的更多的喷嘴,以及不包括第一组的喷嘴的燃烧器中的燃料朝向第二组的一个或多个喷嘴的关闭流动。 构成:在多个燃烧器(10)的出口端连接到涡轮的入口端并将高温燃烧气体供应到涡轮机的装置中,并且每个燃烧器(10)设置有多个喷嘴(14) ),将燃料供给到通过主供给引导管(22)和控制阀(24)并联连接有多个燃烧器供给管路(26)的歧管(28)和多个喷嘴( 14)连接到燃烧器供给管路(26)。 燃料分配阀(30)设置在供给管路(26)中,在燃料分配阀(30)上配置有用于通过分级控制阀(44)从空气供给源(40)供给空气的气动装置, 具有规定量的燃料通过远程操作控制阀30而被供给到第一组的喷嘴,并且关闭燃料被供给到第二组的喷嘴。
