A group of industrial gas turbine fuel controls has recently been developed which shows considerable promise for use on industrial gas turbines. The basic design philosophy was to provide fuel controls consisting of fuel metering valves and standard industrial governors to meet the majority of individual customer requirements. These new metering valves schedule fuel flow as a function of compressor discharge pressure, and include flow schedule biases by inlet temperature and turbine temperature, and adjustments for fuel specific gravity and Btu content.
