载氧体燃烧联合循环部分负荷性能分析

PART-LOAD PERFORMANCE OF A COMBINED CYCLE WITH OXYGEN-CARRIER COMBUSTION

本文对载氧体燃烧联合循环的部分负荷性能进行了研究,并与四种调节方式下的常规联合循环的部分负荷性能进行了比较。分析表明,载氧体燃烧联合循环的部分负荷性能优于压气机进口导叶(IGV)不可调的常规联合循环,但在IGV可调范围相同的条件下,常规联合循环的部分负荷性能优于载氧体燃烧联合循环。

Part-load performance of a combined cycle with oxygen-carrier combustion is studied and compared with the conventional combined cycle in four part-load control strategies, respectively. The study shows that the part-load performance of the combined cycle with oxygen carrier combustion is better than that of the conventional combined cycle without any inlet guide vane （IGV） control of the compressor. While, in the condition that the compressor＇s IGV can change same angle, the part-load performance of the conventional combined cycle is better.
