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.
摘要翻译：一种组合式燃气轮机设备包括空气压缩机，包括燃烧室，燃气轮机，蒸汽轮机和具有脱硝装置的排气热回收装置的燃烧器，并且设置在排气通道中，从燃气轮机到大气延伸。提供了一种配备有阀的抽气管，用于从空气压缩机中提取一部分空气，以防止在启动设备期间空气压缩机的浪涌，并且提供另一个装有阀的空气抽取管，用于提取一部分来自空气通道的空气从压缩机延伸到燃烧室，以提高火焰的稳定性和在工厂起动期间在燃烧室中的可燃性。提取管延伸到并因此将抽出的空气引入位于脱硝装置下游的排气通道的一部分。
