Abstract
A fuel system is configured to deliver a first fuel and/or a second fuel to a combustor section. The fuel system includes a first fuel source, a second fuel source, a first control valve, a second control valve, a metering valve and a fuel injector. The first fuel source is configured to crack ammonia into hydrogen gas and nitrogen gas and subsequently output the first fuel. The second fuel source is configured to output the second fuel. The metering valve is configured to meter a flow of the first fuel received from the first fuel source through the first control valve to the fuel injector during a first operating mode. The metering valve is configured to meter a flow of the second fuel received from the second fuel source through the second control valve to the fuel injector during a second operating mode.
