The need for a gas turbine training facility became apparent with the introduction into the U.S. Navy fleet of the first ships of the FFG7 Frigate and DD963 Destroyer Classes with gas turbine propulsion plants. This facility, constructed at the Great Lakes Naval Training Center, provides "hands-on" training for maintenance and operation of marine gas turbines and associated propulsion plant components and controls and their piping and electrical systems. The Navy intends to train at this facility approximately 1000 personnel per year in the use of their latest and newest propulsion plants. The design of the facility reproduces as closely as possible the existing machinery and control spaces of the two different classes of ships and integrates them into a single main building with the school and the mechanical equipment wings. This paper presents an overview of the need for well-trained, qualified naval personnel to man the expanding fleet of marine gas turbine propulsion systems, existing training facilities and the various stages in the development of the FFG7/DD963 Gas Turbine Maintenance and Operational Training Facility. In regard to the facility, the paper discusses the planning and managing of the project; development of the designs for the building and propulsion plants; construction of the building facilities and FFG7 plant; the fabrication, transportation and erection of the FFG7 within the building; and the testing and operation of the FFG7 plant since light-off. Major emphasis is given to the FFG7 plant since the DD963 plant is being reconsidered in conjunction with the CG47 upgrading and is awaiting a decision to proceed.

In this time of energy crisis low production rate against the increasing demand of the gas production regularly hampers both the domestic and industrial operations since natural gas is the major power source of this country. Unless other power source is developed, natural gas is our only hope. Almost all the existing processing plants are now operating beyond their capacities. Nonetheless there has been a dwindling situation in the gas production. Besides political indecision regarding new establishment of gas plant and other power source have made the situation nothing but complicated. In such a case an idea of optimization of the gas processing plant will surely pave a way to a sustainable solution. This project has the intention to carry out the simulation of the Bakhrabad gas processing plant (at Sylhet) using the Aspen-HYSYS process simulator. The steady state simulation of the gas processing plant shall be performed based on both the design and physical property data of the plant.

Exhaust Systems

Industrial and aeroderivative gas turbines use exhaust systems for flow diffusion and pressure recovery. These processes result in a three-dimensional, unsteady, turbulent, and complex flow in the exhaust diffusers. The downstream balance-of-plant systems such as heat recovery steam generators or selective catalytic systems require, in general, a steady, uniform flow out of the exhaust system. Aeroderivative gas turbines for power generation application have a wide operational envelope. Even though the exhaust systems are designed for 70% load to 110% load, its performance is significantly altered at low power operations. Application of gas turbines at low power can increase exhaust diffuser vibrations because of diffuser flow separations and wakes from the last stage of the power turbine. Aerodynamic excitations which result in excessive structural vibration can cause the units to trip and the power plant to stop, resulting in customer revenue loss. The primary motivation for this research is to investigate an aerodynamic mechanism to ensure reliable operation of the exhaust system by identifying the regimes where aerodynamic instabilities can occur. In-house and university supported initiative to predict unsteady aerodynamics at low power conditions shows the presence of turbulent and time dependent flow. The frequency spectrum results are discussed for low power and high power gas turbine operating conditions. The numerical predictions are in good agreement with test results.

After discussion of the design and materials of construction of the RUSTON TA series gas turbines, information relating to applications and lifetimes is given. The main portion of the paper deals with a variety of interesting material problems and their solutions, that have arisen over the years. These have been reported under the headings of: Influence of atmosphere; influence of fuel; influence of temperature; influence of material; and influence of lubricating oil. Finally, reference is made to specific installations and their operating data in order to re-affirm the suitability of the industrial gas turbine as a power source in a very wide variety of demanding applications and environments.

Exhaust Heat

Organic Rankine Cycle (ORC) systems are not new; prototypes have been tested for about a century. The theoretical investigation and practical applications in the past are briefly presented and referenced. This paper presents the applications of this technology, which matured mainly in geothermal applications, to the recovery of exhaust heat of simple cycle gas turbines driving compressors on gas pipelines and gas processing plant. Most of the compressor stations have a capacity below 50 MW and operate basically unattended. The complexity and the necessity of an operator prevents the use of bottoming steam systems (combined cycle) on this size of plant. In these applications, which are mainly retrofits, the ease of operation of the ORC made its use possible where steam turbines were unsuccessful. Two applications are described: the Enterprise Products’ Neptune plant in Louisiana, and the Gold Creek gas compressor station in Alberta, Canada.

Combined Cycles

The desire to extract ethane and propane from the natural gas produced by off-shore wells in the Gulf of Mexico, led to the erection of the Cryogenic Gas Processing Plant near Erath, Louisiana. This paper describes the application of a combined cycle (gas/steam turbine) for gas compression and transmission. The installation is none of, if not, the largest and most efficient combined cycles in mechanical drive service, capable of handling over 1200 MMscf/d of gas. The installation incorporates a gas turbine rated 46,800 hp at ISO conditions and a steam turbine rated 29,700 hp. In addition, the cycle incorporates the use of gas turbine variable inlet guide vanes, a supplementary fired waste heat recovery boiler and forced draft fan for independent steam turbine operation.

The article provides an overview of modern high-performance combined-cycle plants and gas turbine plants with waste heat boilers. The forecast for the introduction of gas turbine equipment at TPPs in the world and in Russia is presented. The classification of gas turbines according to the degree of energy efficiency and operational characteristics is given. Waste heat boilers are characterized in terms of design and associated performance and efficiency. To achieve high operating parameters of gas turbine and boiler equipment, it is necessary to use, among other things, modern water treatment equipment. The article discusses modern effective technologies, the leading place among which is occupied by membrane, and especially baromembrane methods of preparing feed water-waste heat boilers. At the same time, the ion exchange technology remains one of the most demanded at TPPs in the Russian Federation.
