摘　　要：考虑到低热值燃气的热值和成分均不稳定,对低热值气体中所含有的可燃气体H2,CO,CH4的燃烧特性进行了研究,在理论上提出了一种可行性解决方法,即:燃气轮机在燃烧低热值气体燃料时,可以根据可燃气体成分的变化情况,添加一定量的H2,CO,CH4中的一种或几种,使燃烧可以稳定进行。同时也列举出了燃气轮机燃烧低热值气体所存在的其它问题,并提出了可行性解决方法。Considering the unstable calorific value and composition of low heat value gas,this paper investigated the combustion characteristics of flammable gases H2 ,CO and CH4 in low heat value gas and put forward a theoretically feasible countermeasure, by which some of H2, CO or CH4 is added in response to the change in gas composition to stabilize the combustion of low heat value gas in gas turbine. Moreover,this paper also enumerated other problems in gas turbine when burning low heat value gas and proposed feasible solutions.
