Abstract: Embodiments of the present disclosure include methods, systems and program products for controlling a water bath heater for a fuel gas. Methods according to the present disclosure can include: calculating at least one calculable condition of the fuel gas based on a set of conditions of the fuel gas entering the water bath heater and a type of control valve located downstream of the water bath heater; calculating a target temperature differential for the fuel gas based a set of conditions of the fuel gas entering the water bath heater and the at least one calculable condition; and adjusting an operating parameter of the water bath heater to adjust a temperature of the fuel gas leaving the water bath heater by the target temperature differential.

Abstract: A system includes an inlet duct disposed about an inlet axis, wherein the inlet duct is configured to direct an airflow along the inlet axis to a compressor inlet. The inlet includes an inlet heating system and a heating portion having a longitudinal axis that is substantially perpendicular to the inlet axis. The inlet heating system includes a first conduit substantially parallel to the longitudinal axis that is configured to distribute a heated fluid directly to the airflow via a first set of openings of a first end zone of the first conduit and a second set of openings of a second zone of the first conduit. The first end zone is configured to receive the heated fluid from a heating source, the second zone is coupled to the first end zone, and the second zone is configured to receive the heated fluid from the first end zone.

Abstract: An exhaust processing system that includes: an exhaust passageway for directing exhaust gases, the exhaust passageway having passageway walls that define and enclose the exhaust passageway between an upstream position and a downstream position; and an acoustic liner formed against and covering at least one of the passageway walls of the exhaust passageway. The acoustic liner may include uniformly configured modular acoustic blocks fitted against each other. The modular acoustic blocks each may include interior cavities having different lengths configured to dampen targeted sound frequencies.

Abstract: A system includes a gas turbine system having a first compressor, a combustor, and a turbine, where the first compressor provides a first portion of a discharge air directly to the combustor. The system includes a fluid circuit which receives a fluid comprising a second portion of the discharge air from the first compressor or a combustible fluid and provides the second portion of the discharge air to fuel at a location upstream of the combustor to alter a chemical and physical characteristic of the fuel in an air-fuel mixture that is provided to the combustor.

Abstract: A gas monitoring system for monitoring gas leaks from a gas turbine engine disposed within a gas turbine enclosure includes a controller including a processor and a memory communicatively coupled to the processor. The memory stores instructions which when executed by the processor perform operations including obtaining one or more operational parameters associated with a gas turbine system having the gas turbine engine from one or more sensors during operation of the gas turbine engine. The operations also include utilizing a gas leakage monitoring model to monitor for gas leaks within the gas turbine enclosure and to generate a gas index indicative of a severity of a gas leak within the gas turbine enclosure based on the one or more operational parameters. The operations further include outputting the index.
