Experimental Study of the Hydrogen Co-Firing Characteristics on the Gas Turbine Combustor and Operational Stability Assessment
Year: 2025
Type: article
Abstract: Hydrogen is a key fuel for reducing greenhouse gas emissions in the gas turbine sector, but its combustion characteristics differ from natural gas and may impair combustor stability.Power producers are considering its applicability, although assessing co-firing limits remains largely within OEMs.In this study, hydrogen co-firing tests were conducted under atmospheric conditions to evaluate combustion characteristics and stable operating limits.As the hydrogen ratio increased, nitrogen oxide concentrations rose while carbon monoxide decreased, and combustion dynamics exhibited pronounced low-frequency variations.The surface temperature of combustor hot-section components also showed location-dependent behavior.
