Abstract

A gas turbine uses a first fuel at full load and an improved emission behavior is achieved by operating the gas turbine (11) at partial load with a second fuel, which has a richer mix of higher-value hydrocarbons (C2+) with 2 and more carbon atoms per molecule like ethane (C2H6) and propane (C3H8).
