广东省引进燃气-蒸汽联合循环机组的必要性及机组性能分析

Necessity of developing gas-steam combined cycle units in Guangdong and performance analysis of the units

阐述了广东省引进燃气-蒸汽联合循环机组的必要性,以及该类型机组的燃料供应问题。通过与常规火力发电机组比较,分析了燃气-蒸汽联合循环机组在效率、环境保护、耗水量等方面的优越性。针对现今国际上的主导机型———F级燃气-蒸汽联合循环机组,就机组性能和结构优化配置方案进行了分析比较,认为:F级燃气轮机适于建造联合循环机组;作为两班制的调峰机组,单轴机组比多轴机组更具优势。

This paper expounds the necessity of developing gas-steam combined cycle units in Guangdong, China as well as the fuel supply for this kind of units. Through the comparison with conventional thermal generator sets, the superiorities of gas-steam combined cycle units in efficiency, environmental protection, water consumption, etc. are analyzed. In light of the internationally dominant F-class gas-steam combined cycle units, a comparative analysis is made of the unit performance and configuration optimization scheme. It is concluded that F-class gas turbines arc suitable for combined cycle units, and single-shaft units are superior to multi-shaft ones as two-shift peaking units.
