Method and device for controlling a gas-turbine plant

摘要

A method for controlling a gas-turbine plant that can operate with fluid fuel envisages the steps of:
determining a theoretical regulation flow rate (Q5) of fluid fuel to be supplied to a combustion chamber (4) of the plant (1) on the basis of a power requirement (PR) for the plant (1);
determining a diffusion flow rate (Q2) on the basis of the theoretical regulation flow rate (Q5), equal to at least a minimum diffusion flow rate (QDmin); and
supplying by diffusion the diffusion flow rate (Q2) to the combustion chamber (4).
