摘　　要：使用CHEMKIN软件,分析了同热值不同组分中低热值燃料对燃气轮机燃烧特性的影响。保证热值相同的情况下,采用天然气掺混氮气、一氧化碳、氢气掺混氮气3种不同组分的燃料,研究了当量比和燃烧室进口温度分别对绝热火焰温度、燃烧室出口温度、CO排量和NO排量的影响。结果表明:同热值不同组分中低热值燃料的燃气轮机燃烧特性不同,且中低热值燃料中可燃气体所占比例越大,绝热火焰温度和燃烧室出口温度越高。In the paper,the influences of component of low-calorific-value fuel gas on combustion characteristics of gas turbine were analyzed by CHEMKIN software. Effects of equivalence ratio and inlet temperature of combustor on adiabatic flame temperature,outlet temperature of combustor,emissions of CO and NO were investigated using three kinds of low-calorific-value fuel gas with the same calorific value. The fuel gases were mixture of natural gas and nitrogen,carbon monoxide and mixture of hydrogen and nitrogen,respectively. The results showthat different components of fuel gas lead to different combustion characteristics of the low-calorific-value fuel,despite the same calorific value. The more the proportion of combustible gases in fuel gas,the higher the adiabatic flame temperature and outlet temperature of combustor are.
