Title:
VARIABLE FUEL HEATING VALUE ADAPTIVE CONTROL FOR GAS TURBINE ENGINES
Document Type and Number:
WIPO Patent Application WO2000052315
Kind Code:
A3
Abstract:
A control and method is provided that continuously adjusts fuel sensitive schedules in an electric control unit (ECU) for changes in the heating value of the fuel being combusted by the engine. The control and method includes calculating, as the engine is running, an expected fuel flow for a baseline fuel type and an actual fuel flow. A ratio of these two fuel flows is determined and applied to the heating value of a baseline fuel type that is preprogrammed into the ECU. This results in a scale factor that is then applied to fuel sensitive schedules in the ECU.
