Abstract: A method includes blending a first fuel with a second fuel in a ratio to produce a third mixed fuel. The first fuel has a first heating value, the second fuel has a second heating value, and the third mixed fuel has a third heating value. In addition, the first heating value is different than the second heating value. The method also includes feedforward controlling the third heating value of the third mixed fuel via prediction and correction of a fuel flow rate of the first and/or second fuels to adjust the ratio of the first and second fuels based at least in part on a comparison between a measurement and a target for the third heating value.

Abstract: The present invention provides a method of controlling a turbomachine having at least one fuel supply system that uses an unchoked valve. Here, the method may determine the flow characteristics of a fuel in a fuel supply system without using a flow meter. The present invention also provides a fuel supply system with a configuration comprising at least one unchoked valve. The fuel system may not require the use of a flow meter.

Abstract: A method of operating a power generation system is provided. The system includes a first gas turbine engine that uses at least one of a primary fuel and a secondary fuel, and at least one second gas turbine engine that operates using at least one of a primary and secondary fuel. The method includes supplying primary fuel to at least one of the first and second engines from a common fuel source coupled to the first and second engines, and selectively operating the first engine between a first operational position and a second operational position. The first engine using only secondary fuel in the first operational position and operates using only primary fuel in the second operational position. The method includes supplying the second engine with primary fuel from the common fuel source without flaring the primary fuel.

Abstract: Methods and systems for a gas moisturizing system are provided. The system includes a plurality of gas sources configured to supply a flow of gas to a plurality of gas loads, a single gas moisturizer coupled in flow communication to the plurality of gas sources and the plurality of gas loads wherein the single gas moisturizer is configured to supply a flow of gas having a predetermined moisture content to the plurality of gas loads, and a control system configured to maintain the predetermined moisture content.

Abstract: An embodiment of the present invention provides a method of controlling a turbomachine having at least one fuel supply system that uses an unchoked valve. Here, the method may determine the flow characteristics of a fuel in a fuel supply system without using a flow meter. An embodiment of the present invention may provide a fuel supply system with a configuration comprising at least one unchoked valve. Furthermore, this embodiment of the present invention may comprise a fuel supply system that does not include a flow meter.
