System Operating

In the late 1970’s, due to increasing electric energy costs and the potential for power interruption at Solar Turbines Incorporated’s Harbor Drive manufacturing facility, management evaluated several self-generating options available at the time. With large fluctuating loads and a very limited need for thermal energy, the appropriate solution was determined to be peak shaving. In 1980, a 2.5-MW dual fuel industrial gas turbine generator set was installed. Its intended operating cycle was during on-peak billing periods, 5 days a week throughout the year. Through August 31, 1993, the system has accumulated 22,743 hours of use and 3879 starts. Its overall start reliability has been 99.9% with an availability of 98.2%. Payback on the installation was in 4.2 years. It has continued to generate savings since installation, with net savings for 1992 alone exceeding $470,000. This paper highlights the key aspects of the economic methodology justifying installation of the peak shaving system, operating procedures, maintenance practices and system modifications put in place over the life of the installation.

The Rolls-Royce Allison (RRA) 501-K34 serves as the prime mover for the Ship Service Gas Turbine Generator sets (SSGTGs) of the U.S. Navy’s DDG-51 Class ships. Navy experience with the 501-K34 began in 1988 with the testing of the first prototype. Experience to date includes over 700,000 fired hours on a growing fleet of engines. This paper explores that operating experience and discusses future plans to improve the engine’s operational availability while lowering life cycle costs.

Most gas turbine generators rely on an automatic-engaging, free-wheel clutch to connect a starting motor to accelerate the gas turbine generator from zero to some intermediate speed to enable ignition and then provide torque assistance to a higher speed until the gas turbine is self-sustaining. The U.S. Navy has used various designs of starter motors and clutches for its gas turbine fleet. In addition, there has been a requirement to periodically borescope each gas turbine, which has necessitated removal of the starting system and clutch assembly in each instance. This paper examines the U.S. Navy experience with starting clutches and provides details of the development and testing of a synchronous-self-shifting clutch with an additional, stationary, manual turning feature to provide very slow and precise gas turbine rotor rotation for borescope purposes. This paper also gives details of the installation of the first two prototype clutches on the USS Ramage, DDG 61, operating experience for approximately four years, and possible future installations of this type of clutch in U.S. Navy gas turbine generator sets.

This paper describes two gas turbine power plants in Libya which use multiple units of the Westinghouse W191G ECONO-PAC as turbine-generator sets. Special design considerations in the crude and residual fuel burning capability and system performance on instant electrical load pick-up are described in detail. The field test results of the turbine control system are also summarized in this paper. In addition, some of the operating experience in the fuel system and gas turbine combustion system is discussed briefly.

This paper is intended to cover the operating experiences of the Gas Turbine Generating Unit at the Sewaren Generating Station of the Public Service Electric and Gas Company. This gas turbine is powered with eight aircraft-type jet engines and is rated at 140,000 kw. It completed two years of service in November 1967 and has accumulated more than 1600 hr of service. The problems and experiences associated with the unit in this period are reviewed.

Steam Production

Topping cycle cogeneration plants, consisting of a relatively small gas turbine generator (3–5 MW) and a supplementary fired heat recovery steam generator designed to maximize steam production, are becoming a very attractive system design. Special burners designed to fire into water wall furnaces can add substantial steam production capability to the system in a very efficient manner, utilizing the oxygen available in the turbine exhaust. This paper examines recent operating experience at two U.S. installations, using gas turbines rated at 3.3 MW (Iso) and 4. 8 MW (Iso). Gas fired burner designs are presented. Performance parameters such as response to load, maximum steam production, burner rangeability, and emissions of NOx and CO are discussed.
