Use of Modern Gas Turbines in the Current New Constructions Programme of RWE Power AG

Oliver Then

European electric utilities are facing the challenge to renew their power plant portfolio having to take into account requirements regarding climate protection as well as sustainability, competitiveness and supply security. These challenges are reflected within the investment scheme of the RWE group and the new constructions programme of RWE Power in Germany and continental Europe. One component is realised by RWE Power through the application of modern gas turbines in combined cycle power plants using state-of-the-art gas turbine technology that achieves very high efficiencies in base load as well as flexible generation in the medium and peak load market segments.

V93.0 Gas Turbine Modernisation in the E.ON Franken 1 Power Plant

Wilhelm Kleffner and Marcus Gera

High prices for peak power and therewith expansion of electric power in the peak and medium load market lead customer to incorporate the V93.x gas turbines in medium and long term planning. On behalf of E.ON Kraftwerke GmbH, the V93.0 gas turbine in the Franken 1power plant will be upgraded by Siemens Energy to a V93.1 by changing the hot gas path components of the turbine and some auxiliaries. Compared to the former V93.0 design with approximately 53 MW base load power output (simple cycle), this leads to a power output increase of about + 6.29 MW in base load operation and approximately + 7.88 MW in peak load operation.

Economical Benefits and Operating Experience of Modifications for Performance Improvement of Combined Cycle Power Plants

Christoph Kail, Bert Rukes, Wolfgang Märker, Frank Strobelt, Ingo Weber and Klaus Werner

Measures to temporarily increase the output of combined cycle power plants are presented and assessed under technical as well as economical aspects. Wet compression is the most economical way to increase the output of combined cycle power plants followed by additional firing in the waste heat recovery boiler. The measures presented can also be used to support net frequency.

Experience and Application with the Innovative LMS 100 Gas Turbine

Klaus Payrhuber and Dennis Rayome

Quick start-up, high efficiency, high part load efficiency and high operational flexibility at low emissions are the main requirements to be met by new peak load gas turbines. The LMS100® by GE was developed as highly efficient gas turbine and is based on the well-tried design derived from aircraft. It is designed in sizes comparable with heavy duty gas turbines. First operating results and applications for the European market are presented.

Design of Combustion System for the SGT5-8000H and First Experiences in the Irsching Power Plant

Michael Huth

The lean premixed combustion system for the new SGT5-8000H 50Hz H-class engine was scaled from the smaller Siemens 60Hz F-class engine. The paper describes the combustion system in more details and the testing methodology including six sigma approaches. First experiences with SGT5-8000H Prototype-Engine in the Irsching power plant are summarised.

Future Perspectives for High-temperature Gas Turbines

Christoph Lietmeyer, Yavuz Gündogdu, Oliver Kleppa, Karsten Oehlert, Arne Vorreiter and Jörg Seume

Research approaches for reducing operating cost, investment and maintenance expenses for stationary gas turbines are presented. Operating expenses are reduced by increasing compressor efficiency using a functional surface structure which is oriented in flow direction. Within the planned collaborative research centre “Regeneration of durable goods” new scientific fundamentals and research results for the systematic regeneration of gas turbines will be developed.

Introduction of the Solar Turbines Titan 250 Gas Turbine System Design, Development and Validation Testing a New 22.4 MS Gas Turbine

Mark Knodle

The Titan 250 gas turbine, 22.4 kW, and C85 centrifugal gas compressor, are the latest additions to Solar Turbines’ product family. These new products leverage core technologies that have been developed and proven in several other well-established products. The paper discusses the evolutionary design approach used to develop this engine, which was based on shared technologies from three well-established gas turbine systems.

Process Quality Control – Modern Information Technology to Improve Power Plant Efficiency

Andreas Knieschke, Peter Deeskow, Theo Hufmann and Christoph Pels Leusden

In order to achieve the best possible efficiency of their plants, an increasing number of power plant operators employ performance monitoring systems (PM systems). This term is connected with modern IT applications which usually process online transmitted process data, perform performance calculations on this basis and in result provide very precise information of the current quality of energy conversion process.

High Performance for Dandirma with Combined Cycle Technology

Franz Binder and Nicolas Perl

Energy consumption in Turkey is currently increasing between eight and ten per cent per year. To accomplish this challenge, the power generating company Enerjisa, jointly owned and controlled by Sabanci Holding and Verbund/Austria, has taken an early lead in the race to provide the country with electricity it urgently needs with awarding the contract for the Bandirma combined cycle power plant. The plant is to be erected by a consortium consisting of A-TEC Power Plant Systems (A-TEC PPS) and Mitsubishi Heavy Industries (MHI) directly on the Sea of Marmara coast near Bandirma.

Pre-engineering Study for a 700 °C Highly Efficient PC-power Plant

Hans-Joachim Meier

The pre-engineering study project for a high-efficiency power plant with a live steam temperature of 700 °C (Power Plant 700) represents the first stage for the construction of a low-emission power plant, which is to be erected once its technical and economic feasibility has been confirmed. The project has been conceived as a cross-border transnational project. To date, eleven European energy utilities have joined together with the aim of developing this sustainable European concept for generating power on the basis of fossil fuels.

Trace Elements in German Waters

Alfons Wolff

The Directive 2008/105/EG on environmental quality standards in the field of water policy lays down limited values for European surface waters (annual average and maximum allowable concentration). 33 priority substances are concerned. The target is to achieve a good chemical status in the waters in accordance with the provisions and objectives of the Directive 2000/60/EC. The member states are obliged to implement necessary measures with the aim of ceasing or phasing out emissions.

Lignite Production in Nochten/Reichwalde – A Reliable Supplier of Lignite to the Lusatian Markets

Siegfried Körber and Wolfgang Ketzmer

Lignite mining und processing of raw lignite have a long tradition in the region Nochten/Reichwalde. The open-cast mines and power plant are firm part of Vattenfall. The conditions of lignite deposits and modern open-cast mining equipment enabled the economic operation of the Nochten and Reichwalde after German reunification. The newly built and modernised power plant units at the Boxberg and Schwarze Pumpe sites are the main consumers of domestic lignite.
