METHOD AND ASSEMBLY FOR SUPPLYING FUEL TO A COMBUSTION CHAMBER OF A GAS TURBINE PLANT

摘要

A method for supplying fuel to a combustion chamber (4) of a gas turbine plant (1) envisaging supplying lean gas to the combustion chamber' (4) through a lean gas supply line (12) of the plant (1) and supplying natural gas to the combustion chamber (4) through a natural gas supply line (13) of the plant (1), which includes a pilot delivery line (23). In particular, the step of supplying natural gas envisages the measuring of a lean gas calorific value (HVSG), calculating at least a first natural gas flow rate (QNGp) to be supplied to the combustion chamber (4) through the pilot delivery line (23) on the basis of the measured lean gas calorific value (HVSG), and supplying at least the first natural gas flow rate (QNGp) to the combustion chamber (4) through the pilot delivery line (23).
