PROBLEM TO BE SOLVED: To solve the problem wherein there is a desire for an improved method of controlling the ignition mode during the start-up of a turbomachine, the method should provide a closed loop methodology that adjusts the fuel flow based on a current heating value, and the method should increase the probability of a successful ignition mode and start-up. SOLUTION: This method adopting the closed loop methodology based on physics is applied to determine a mass flow of fuel required for a sound ignition mode. A turbine control system 190 receives a plurality of operating data. The turbine control system 190 utilizes one algorithm, which applies an energy balance to the received operating data. The operating data may include, but is not limited to, airflow data, data from the fuel system 160, data related to the shaft work, exhaust data, and data related to the heat loss. This energy balance is used to determine the required mass flow rate. COPYRIGHT: (C)2011,JPO&INPIT
