Gas Turbine Engine and Method for Reducing Turbine Engine Combustor Gaseous Emission

摘要

The invention relates to turbine engines used in aeronautics, but also for industrial and marine turbine engines. To reduce turbine engine combustor gaseous emissions at given combustor sizes or to reduce combustor sizes at given combustor gaseous emissions, the invention proposes the injection of hydrogen into the combustor in response to a power output level. According to a preferred embodiment, gaseous hydrogen is always injected at low-power operations and switched off at mid-power and high-power operations.
