METHOD FOR CONTROLLING THE SUPPLY OF FUEL GAS TO A GAS-TURBINE BURNER

摘要

Described herein is a method for controlling the supply of fuel gas (SG, NG) to a burner (3) of a gas turbine; according to said method, a fuel (SM) comprising a gas with low calorific value (SG) is sent to the burner (3) with a flowrate that is regulated as a function of the delivery pressure (p_SG) of a source defined by a gasification plant (5) so as to maintain said delivery pressure (p_SG) above a minimum pressure (pSGMIN); a gas with high calorific value (NG) can be added to the gas with low calorific value (SG) in order to reach a required load (PSX) by regulating the flowrate of the gas with high calorific value (FNG) as a function of the delivery pressure (p_SG) so as to maintain said delivery pressure (p_SG) below a maximum pressure (pSGMAX).
