The only commercially running closed-cycle gas turbine in the world delivering electricity as well as heat to a public utility and a heating network, is the heat and power station in Coburg, West Germany. The plant is fired exclusively with pulverized coal and uses air as the working medium. It has a maximum continuous electric power output of 6.6 MW into the grid and up to 16 MW of direct heating capacity into the town’s heating network. The plant has accumulated 150,000 operating hours to date (approximately 7000 hrs per year); it is scheduled to remain in service during the following years due to its excellent performance. Since relatively little has been published about the plant in the technical literature, a report about its design and operating experience is presented here.

Technical Description

PowerGen's 900 MW combined cycle gas turbine (CCGT) power station at Killingholme achieved full load output over two months before the scheduled date for full commercial load and less than 34 months after the turnkey contract was placed. This paper reviews the development of PowerGen's first CCGT power station, discusses the reasons for the choice of this type of plant and examines early operating experience. The contract strategy, a technical description of the plant, the project programme and the environmental impact of the plant relative to a conventional coal-fired power station are also included.

Study Results

This paper presents a discussion of the significant results of a study program conducted for the Department of Energy to evaluate the potential for closed cycle gas turbines and the associated combustion heater systems for use in coal fired public utility power plants. Two specific problem areas were addressed: (a) the identification and analysis of system concepts which offer high overall plant efficiency consistent with low cost of electricity (COE) from coal-pile-to-bus-bar, and (b) the identification and conceptual design of combustor/heat exchanger concepts compatible for use as the cycle gas primary heater for those plant systems. The study guidelines were based directly upon the ground rules established for the ECAS studies to facilitate comparison of study results. Included is a discussion of a unique computer model approach to accomplish the system analysis and parametric studies performed to evaluate entire closed cycle gas turbine utility power plants with and without Rankine bottoming cycles. Both atmospheric fluidized bed and radiant/convective combustor /heat exchanger systems were addressed. Each incorporated metallic or ceramic heat exchanger technology. The work culminated in conceptual designs of complete coal fired, closed cycle gas turbine power plants. Critical component technology assessment and cost and performance estimates for the plants are also discussed.

Design Construction

At the moment the closed-cycle gas turbine attracts considerable attention due to: 1 The possibility of directly coupling the closed-cycle gas turbine with a gas-cooled high temperature reactor; 2 the economical use of dry coolers to reduce the thermal charge of the environment; and 3 the reduction of pollution and energy consumption, by replacing the domestic hearth by a central heating and power station. The experience gained in the development, design, construction and operation of the closed-cycle gas turbines at present in service is to be used for these new applications. In this paper, four closed-cycle gas turbine plants in operation in Europe are described and the experience obtained is summarized. The incorporation of the experience gained with these plants in the design and construction of future closed-cycle gas turbines using helium as a working medium is shown with the example of a 50 MW helium turbine. The combined application of experience and a new design philosophy results in a rather unconventional gas turbine.

Working Medium

The tubes for the receiver of a solar power plant are designed taking into account thermal and mechanical loads. The receiver transfers 60 MW of heat to the working medium of a closed cycle gas turbine, the medium being air. It is shown how the stress pattern in the tubes are influenced by the distribution of the locally absorbed heat flux, assuming linearly elastic deformation of the tube material. Criteria for the influence of the partially plastic behavior of the tubes are discussed for different distributions of the intensity of the absorbed heat flux.

This is a progress report on the marine gas turbine and free-piston gas turbine during the 5-yr period, 1953–1957. Since the merchant and naval services encompass many similar operating conditions—in spite of many differing requirements—the entire marine field will be reviewed in a single paper. In the first report [18], separate papers appeared on marine, merchant, and naval applications. Open and closed-cycle gas-turbine, nuclear gas-turbine, and free-piston gas-turbine prime movers will be discussed along the following lines: Applications, operating experience, development, advantages, disadvantages, economics, and the future potential in the marine field.

Thermal Power Stations

The closed-cycle gas turbine can be applied in thermal power stations using fossil, nuclear or solar energy. Here the behavior of the closed-cycle gas turbine plant under time dependent operating conditions is particularly important. A theoretical model was developed which unlike previously applied methods also considers the transient processes in the heat exchanging units, the heat transfer between the working medium and the internally insulated hot-gas pipes, and the condition of the blading. For examination of the model, measurements were taken on a closed-cycle air turbine. The results of the calculation made for comparison with the test results show the reliability of the calculation model. There is conformity of the measured speeds of the turbo group and of the pressures, temperatures and mass flows of the cycle with the theoretical values until a new steady-state condition is reached.

Under Construction

The Oberhausen gas turbine plant now under construction is designed as a fossil-fired heating power station to produce a net electrical output at terminals of 50 MW. Helium as a working medium is employed for the first time in a closed-cycle industrial power plant system. A report is given on the layout of the circuit parameters, on the physical size of the turbomachines and heat exchangers as well as on the design of the gas-fired helium heater. Moreover, the arrangement of circuit components is discussed. The Oberhausen plant was projected under the aspect of a commercial thermal power station. Besides, the plant is of considerable importance concerning the German program for developing high-temperature reactors with helium turbines (HHT). Its significance is, on the one hand, based on the fact that the turbomachines and heat exchangers are constructed in many details to meet the requirements which occur in nuclear helium turbines of high output. Some of these components closely resemble dimensions and stresses as in a HHT-power plant. On the other hand the operational behavior of component parts will be tested under real conditions of a commercial power plant.
