A106 Upgraded lineup of KAWASAKI Green Gas Turbine combustion systems(Gas Turbine-2)

抄録

The 3rd generation of Dry Low Emission (DLE) combustion system for 8MW-class gas turbine to guarantee <15 ppm NOx emissions(O_2=15%) was developed and introduced to the production lineup of KAWASAKI Green gas turbine. One of the characteristic design concepts of KHI's DLE system is using supplemental fuel burner in the combustor, which is a kind of combustion staging technology. For the 3rd generation DLE system, the burner design of main and supplemental combustion system were upgraded by means of Computational Fluid Dynamics (CFD) fuel-air mixing and also experimental evaluation. The new designed main and supplemental combustion system showed successful results to achieve the emissions target of the 3rd generation DLE system.
