摘　　要：中低热值燃料燃气轮机对于我国建立清洁高效的能源体系具有重要作用。本文针对某型燃气轮机燃用天然气和中低热值燃料的性能进行模拟研究。单一调节方案结果表明：采用提高压比、关小压气机进口导叶、增加透平通流面积三种方案时性能较好,而降低燃烧室出口温度和压气机出口抽气方案性能较差。对多种复合方案进行比较,发现适当增大透平通流面积、关小进口导叶并允许适当提高压比、降低燃烧室出口温度的四方案联合调节,使燃气轮机性能总体较优。The gas turbine based on low-Btu fuel plays a big role in the clean and efficient energy system in China.An industrial gas turbine is modelled in the presented work to investigate the performances of the machine based on natural gas and low-Btu fuel.Based on the analysis of the single control strategies,it is indicated that＂improve pressure ratio＂,＂close guide vanes partially＂,＂expand the turbine＂are favorite methods while＂derating＂and＂air separation＂are disagreeable. Based on the investigations on the compound strategies,it is suggested that combination of＂improve pressure ratio＂,＂close guide vanes partially＂,＂expand the turbine＂,＂derating＂can make much profit for gas turbine performance with low-Btu fuels.
