燃气轮机掺氢燃烧对燃烧稳定性的影响OA

Under the context of"dual carbon"goals,power-to-hydrogen has become an important means to address the issue of curtailed wind and solar power.Hydrogen blending combustion technology of gas turbine has attracted significant attention due to its excellent environmental friendliness and operational flexibility in start-up and shutdown.Through theoretical analysis and simulation tests,the feasibility of hydrogen blending combustion was researched,and a hydrogen blending combustion test with a maximum hydrogen volume fraction of 7％ was conducted so as to study the impact of hydrogen blending on combustion stability of gas turbine.The results indicated that after hydrogen blending,the values of the combustion humming signal and acceleration signal showed no significant changes compared to those during natural gas combustion.The monitored temperature data of the burner was normal,and there was no backfire phenomenon.Therefore,a hydrogen blending ratio of 0％ to 7％ has no adverse effect on combustion stability of gas turbine.The research findings can provide reference for subsequent hydrogen blending combustion project for gas turbine with larger hydrogen blending ratio.
