[en] This power station audit reports that more than 14GW of gas fired power plant is due to be built in the UK over the next five years. Details of power stations over 30 MW under construction, planned fuel conversions, proposed power stations, and projects less likely to go ahead are presented, with dates, locations, partners, capacity and names of main contractors given.

[en] Gas turbines are of interest for biomass applications because, unlike steam turbines, they have relatively high efficiencies and low unit capital costs in the small sizes appropriate for biomass installations. Gasification is a simple and efficient way to make biomass usable in gas turbines. The authors evaluate here the technical requirements for gas turbine power generation with biomass gas and the status of pressurized biomass gasification and hot gas cleanup systems. They also discuss the economics of gasifier-gas turbine cycles and make some comparisons with competing technologies. Their analysis indicates that biomass gasifiers fueling advanced gas turbines are promising for cost-competitive cogeneration and central station power generation. Gasifier-gas turbine systems are not available commercially, but could probably be developed in 3 to 5 years. Extensive past work related to coal gasification and pressurized combustion of solid fuels for gas turbines would be relevant in this effort, as would work on pressurized biomass gasification for methanol synthesis

[en] Stewart ampersand Stevenson, a major supplier of gas turbine powered cogeneration systems to worldwide markets, established plant management, operations and maintenance capabilities in 1985 in order to provide complete service capability to the customer. As of the fall of 1993, twenty-two individual cogeneration facilities are now being operated and maintained by this company with a total capacity of 1100+ MW. More than 300 plant management and operating personnel are employed in this operation. To date, activities have been concentrated in North and South America. Negotiations are in process in a number of other areas including the Pacific Rim, China, and several Middle East countries. 7 figs

[en] Technical feasibility to create on the basis of aircraft engines reverse gas-turbine power plants for 6000 and 2500 kW, permitting to substitute them for diesel generators at NPP with a considerable economic effect, has been substantiated. Multiple increase in the capacity of starters and assembly replacement, which transmit the torque from them to the main engine shaft permit to ensure their start in 15-20 s. Further decrease in power supply break can be achieved at the expense of additional installation of compressorless gas turbine, operating with stored compressed air during gas-turbine engine start

[en] Asea Brown Boveri (ABB) has completed its technology based program. The results developed under Work Breakdown Structure (WBS) 8, concentrated on technology development and demonstration have been partially implemented in newer turbine designs. A significant improvement in heat rate and power output has been demonstrated. ABB will use the knowledge gained to further improve the efficiency of its Advanced Cycle System, which has been developed and introduced into the marked out side ABB's Advanced Turbine System (ATS) activities. The technology will lead to a power plant design that meets the ATS performance goals of over 60% plant efficiency, decreased electricity costs to consumers and lowest emissions

[en] An analysis of contemporary cogeneration technologies and power plants with small and average capacities is performed. The spheres of their applications are refined

[en] The discussion panel was chaired by Peter Heffernan, Sales Manager of Power Generation for Union Gas Ltd. He was assisted on the panel by Rheal Caron, Plant Manger of West Windsor Power. Heffernan described several natural gas cogeneration projects across the province, such as the 116 MW Northland Power Facility at Iroquois Falls, the 40 MW project, undertaken by TransCanada Pipelines to recover heat from gas compressor stations at North Bay and Kapuskasing, the 110 MW Destec installation in Kingston, and the 50 MW Windsor-Essex cogeneration plant which relies on the Chrysler Canada auto plant as steam host, and features low NOx technology. Rheal Carron discussed the problems encountered in bringing the 103 MW nominal capacity West Windsor Power facility online. The plant, online since May 1996, supplies base-power between October and April, and is operated on a dispatch basis during the summer weekends

[en] Nuclear power plants produce low carbon emissions and stable, low cost electricity. Combined cycle gas-fired power plants are cheap and quick to build and have very flexible operation. If you could combine these two technologies, you could have an ideal base-load power plant. (authors)

[en] The conceptual design study for the Gas Turbine High Temperature Reactor (GTHTR300) was completed in 2004. In GTHTR300, SECO (Simple, Economical Competitiveness and Originality) is advocated as design philosophy in order to minimize technical and economical requirement. Furthermore the design of the GTHTR300 was developed with reflecting various view points from utilities, manufacturers and research organizations. In GTHTR300, the horizontal turbo machine rotor, the turbo machine in a separated vessel, the turbo machine with single rotor, the generator inside the power conversion vessel, and the power conversion system without inter-coolers were selected as major power conversion system concepts. This paper describes the investigation and analysis about the major concepts of GTHTR300 power conversion system in order to evaluate reasonableness of GTHTR300 design approach and acceptability with using experience and engineering knowledge of Mitsubishi Heavy Industries, Ltd., which were accumulated through the activities of HTGR-GT and HTTR (High Temperature Engineering Test Reactor) designing, manufacturing, fabricating and testing. From the result of the evaluation, it was concluded that the selection of each concept in GTHTR300 was reasonable as based on the original design philosophy SECO. As a conclusion, we expect the GTHTR300 to become one of the most promising concepts for commercialization in near future. (authors)
