一种燃气轮机空气启动装置及系统
摘要：
本发明公开了一种燃气轮机空气启动装置及系统，以降低启动负荷、提高启动稳定性。该燃气轮机空气启动装置包括压缩机、压气机、截止阀、第一气流管路、第二气流管路和第三气流管路，其中，压缩机的进气端与第一气流管路的出气口连通，出气端与第二气流管路的进气口连通；压气机的进气端与第二气流管路的出气口连通，出气端与第一气流管路的进气口连通，压气机还包括从大气中吸入气流的开放式进气端；第三气流管路的进气口与第一气流管路的进气口连通，出气口与燃气轮机的燃烧室连通；截止阀设置于第一气流管路和/或第二气流管路上。相比现有技术，本发明启动负荷小、启动平稳、简单易操作、安装方便快捷，便于推广应用。
摘要（英）：

The invention discloses an air start device and system for a gas turbine so as to reduce start loads and improve start stability. The air start device for the gas turbine comprises a compressor, a gas compressor, stop valves, a first gas flow pipeline, a second gas flow pipeline and a third gas flow pipeline. The gas inlet end of the compressor communicates with a gas outlet of the first gas flow pipeline. The gas outlet end of the compressor communicates with a gas inlet of the second gas flow pipeline. The gas inlet end of the gas compressor communicates with a gas outlet of the second gas flow pipeline. The gas outlet end of the gas compressor communicates with a gas inlet of the first gas flow pipeline. The gas compressor further comprises an open type gas inlet end for sucking gas flow from the atmosphere. A gas inlet of the third gas flow pipeline communicates with the gas inlet of the first gas flow pipeline. A gas outlet of the third gas flow pipeline communicates with a combustion chamber of the gas turbine. The stop valves are arranged on the first gas flow pipeline and/or the second gas flow pipeline. Compared with the prior art, the air start device and system are small in start load, stable in start, simple, easy to operate, convenient and rapid to install and convenient to popularize and apply.
