Abstract

An operating system includes a fuel and control sub-system which includes a main gas circuit, a start gas circuit, a dual fuel nozzle, and a plurality of metering valves. The fuel and control sub-system is configured to transition the operation of the engine from operating with a start gas having a high heating value to using a main gas having a low heating value. The sub-system is further configured to inject water into the gas turbine and permits a user to adjust an overall fuel heating value to improve flammability limits and avoid regions of combustor acoustics.
