    • A nitrogen compressor in an IGCC (integrated gasification, combined cycle) system provides gaseous nitrogen to be directly injected into the combustor of a gas turbine in the IGCC. The nitrogen is injected at substantially the same pressure as the output pressure from the nitrogen compressor. The compressor is controlled to adjust the output pressure of the nitrogen to match a nitrogen injection pressure for the combustor. By controlling the flow (pressure) of the nitrogen injected to a combustor of a gas turbine at the nitrogen compressor, the compressor is relieved of having to overcome the pressure loss through the nitrogen injection valves (which valves are run at or near full open throughout the operation of the nitrogen injection process), and does not need to provide nitrogen at a pressure substantially greater than the nitrogen pressure injected into the combustor.
    • IGCC(综合气化,联合循环)系统中的氮气压缩机提供气态氮气直接喷入IGCC燃气轮机的燃烧室。 以与来自氮压缩机的输出压力基本相同的压力注入氮气。 控制压缩机以调节氮气的输出压力以匹配用于燃烧器的氮气注入压力。 通过控制喷射到氮气压缩机上的燃气轮机的燃烧器的氮气的流量(压力),压缩机不需要通过氮气喷射阀克服压力损失(该阀门在全开或全部运行 氮气喷射过程的操作),并且不需要在基本上大于喷射到燃烧器中的氮气压力的压力下提供氮气。
