This paper evaluates and demonstrates how the public domain data provided by individual interstate pipeline companies to FERC, when combined with individual company equipment lists, can be used to regress industry information on cost of operations and maintenance, fuel gas used, and cost of fuel and power. The paper describes the methods of analysis and identifies their limitations. The paper presents results of such regression analysis as average and variance of cost and fuel usage for industrial gas turbines and aeroderivative gas turbines. It provides further comparisons between gas turbine prime movers, reciprocating engine prime movers, and electric motor drives, and presents annual costs per installed horsepower as a function of turbine size. The paper is based on work performed for PRC International and the Gas Research Institute. [S0742-4795(00)01003-6]

Industrial Gas Turbines

Industrial Gas Turbines allow operation with a wide variety of gaseous and liquid fuels. To determine the suitability for operation with a gas fuel system, various physical parameters of the proposed fuel need to be determined: heating value, dew point, Joule-Thompson coefficient, Wobbe Index, and others. This paper describes an approach to provide a consistent treatment for determining the above physical properties. Special focus is given to the problem of determining the dew point of the potential fuel gas at various pressure levels. A dew point calculation using appropriate equations of state is described, and results are presented. In particular the treatment of heavier hydrocarbons, and water is addressed and recommendations about the necessary data input are made. Since any fuel gas system causes pressure drops in the fuel gas, the temperature reduction due to the Joule-Thompson effect has to be considered and quantified. Suggestions about how to approach fuel suitability questions during the project development and construction phase, as well as in operation are made.

The expenditures for inspection and maintenance of gas turbines are an important part of the total owning and operating costs. Maintenance outage time should be kept to a minimum. A proper design with adequate ports facilitates visual and boroscope inspection of critical areas. Maintenance outage time can be considerably reduced by special equipment which allows inspection and replacement of bearings and combustor inner parts and balancing of rotors without major disassembly of the unit. The advantages of an indoor installation with overhead crane with respect to maintenance are also discussed in this paper.

This paper describes the successful development and application of industrial gas turbines using alternate gaseous fuels. These fuels include liquid petroleum gas, medium-Btu fuels derived from biodegradation of organic matters found in sanitary landfills and liquid sewage, and ultra-low Btu fuels from oilfield fireflood operations. The analyses, mathematical modelling and rig verification performed in the development are discussed. The effects of burning these alternate fuels on the gas turbine and its combustion system are compared to those of using standard natural gas fuel. Gas turbine development required to use other alternative gaseous fuels is also assessed.

Prime Movers

Due to the recent popularity of small and medium-sized industrial gas turbines in many fields, gas turbines below 100 SHP have been employed as prime movers, a power range traditionally reserved for diesel and gasoline engines. Generally speaking, however, small gas turbines have many design difficulties in thermal efficiency, high rotational speed, compact auxiliary equipment, etc., derived from limitations of their dimensions. Small gas turbines S5A-01 and S5B-01, which have 32 PS output power at standard conditions, have been developed and are being produced. Presently, a 30 percent growth rated power producer for S5A-02 and S5B-02 gas turbines is under development. These engines’ configurations are as follows: single-stage centrifugal compressor; single-stage radial turbine; single can combustor; hybrid fuel nozzle with pressure atomizer and airblast atomizer; fuel control valve with pulse width modulation system; electric motor drive fuel pump. In this paper, the authors describe the design features and development history of the base engine and the experimental results with the growth rated version.

Industrial Gas Turbines

The application of industrial gas turbines generally requires more than a detailed energy system analysis. Usually the engineer must “prove-in” his project design to assure that it meets management’s criteria for profitability Several different economic evaluation methods have evolved and there is no one universally accepted practice. This paper illustrates a method of reducing a detailed engineering system design, such as an industrial energy system, to an economic evaluation. This includes developing the minimum investment base case and one or more alternatives which trade off higher first costs for lower operating costs, and then reducing all cases to cold cash — investment and operating costs. Next, three economic evaluation yardsticks are discussed: payout, discounted cash flow, and total owning and operating costs using fixed charges on investment. Advantages and disadvantages of each are pointed out. This includes a discussion of taxes, depreciation, investment tax credit, cash flow, and the time value of money. Finally, computer methods of discounted cash flow are illustrated including a problem with variable annual operating costs. This sets the stage for a “hands on” workshop session using a computer terminal following the presentation.

This paper presents the most important problems which have to be expected when burning residuals and crudes in industrial gas turbines. Solutions for these problems are always influencing the operating costs of the powerplant. Careful economical studies should, therefore, be conducted before one or another fuel is selected. Finally, operating experiences with 14 BBC gas turbines located in Riyadh (Kingdom of Saudiarabia) burning local Khurais crude oil with turbine inlet temperatures of 650 to 850 C are presented.

This article discusses the experience of the US Navy with Synchro-Self-Shifting (SSS) clutches. The US Navy has nearly 40 years of experience using SSS clutches in main reduction gears of gas-turbine-driven ships and propulsion systems with combinations of gas turbines and diesel engines or electric motors, and in steam-turbine propulsion plants for use with electric motor drives. Over 900 SSS clutches have been installed in 14 different classes of US Navy ships, with some having been in service for over 30 years. SSS clutches have accumulated approximately 15,278,000 hours of operation. Mean Time Between Failures in Hours for US Navy clutch applications is relatively high (271,550 hours) based on the operational hours accumulated and the total number of failures that have occurred. The maintenance and repair strategy used for US Navy SSS clutches is similar to a Performance Based Logistics arrangement, where the Navy maintains a rotatable pool of ready-for-issue clutches, and in the event of a problem or failure, the clutch is changed out with an available spare.

This paper reviews the advantages, technical considerations and application of biogas fired Industrial Gas Turbines, and suggests strategies for improving the regeneration of electricity in cane sugar distilleries. Biogas is produced by the anaerobic treatment of waste by the Indian Distillery and allied alcohol based industries. Treatment of waste has been made mandatory and all distilleries in India are setting up such units. With the generation of biogas, the Indian Distillery has found a novel way of converting waste into energy. Traditionally, the biogas obtained was fired in boilers to generate steam. Steam could be used for process or to drive a back-pressure steam turbine. A few small units also considered installing dual fuel reciprocating engines. Recently, a trend setting project of firing biogas directly in a gas turbine to produce electricity and subsequently utilize the hot exhaust gases in a waste heat recovery boiler is being proposed. There are distinct advantages in selecting the gas turbine route over other competing prime movers.
