Planning, Construction and Commissioning of the Iskenderun Power Plant

W.A. Benesch, H. Larisch, and K. Schnadt

The hard coal fired power plant Iskenderun in Turkey with a net capacity of 2 x 605 MW (installed capacity 2 x 660 MW) had been commissioned in 2003 by ISKEN, an associated company of STEAG AG and RWE Power AG. This IPP Project in Turkey presents a challenge in all respects. The scope of this report shall cover the technical peculiarities of the environment-friendly power plant as well as experiences gained from the erection and commissioning phases.

Labour Safety and Health Protection - Integral Elements of Corporate Culture and Business Success

M. Martiny

At a time when organisational processes increasingly tend to be categorised as core and support processes, the question is arising what place and priority labour safety and health protection command in today's and tomorrow's energy sector. It is of major importance how these concepts are embedded in corporate culture, and what impact they have on business success.

The Active Involvement of Employees in the Occupational Safety and Health Management System of RWE Power AG

H. Gröner

Once an occupational safety and health management system has been implemented in a company, the question arises whether managers and employees implement the requirements as planned and intended. We have started a range of actions which are intended to activate the occupational safety and health management system introduced by RWE Power. The wealth of measures enabled us to strengthen awareness of occupational safety and health among staff, and to make the occupational safety management system more transparent.

Operating Experience with the New BoA Unit and Outlook

T. Tippkötter, and G. Scheffknecht

For more than one year the new lignite-fired BoA unit has been operating in the Niederaussem power plant. The experience gained during the first operational year of the new unit is positive despite several unplanned outages. Since the instrumentation and control system is functioning well, start-up and shutdown of the plant are nearly fully automatic. Unexpected events were three cases of damage in 2003 that forced us to put the plant out of operation for a total of 12 weeks. The course of the year 2003 shows that without the above three cases of damage in the first year of operation, generation would have clearly exceeded the expected availability of 70 %.

Efficient Operation of Heating Stations by the Employment of Most Modern Technology

Ch. Wedler, St. Birle, R. Wurm, and R. Nordhausen

The Munich municipal utilities (SWM) supplies the city Munich with electricity and long-distance heating through the two main production plants HKW North and HKW South and HKW Freimann. Due to the liberalisation of the energy market and the increase in costs the SWM decided to realize a modernization concept of the six heating stations for the reserve and peak load cover. These heating stations were converted into plants which could be operated from the distance (="BoB" meaning: operation without continuing supervision).

Experiences with Life Time Extending Measures of DENOX-catalysts in the Combined Heat & Power Plant Heilbronn

J. Matschke, H. Maier, and P. Buck

Once SCR plants have been installed in a power station, the operating and maintenance costs will be mainly driven by the exchange of exhausted catalysts or adding additional layers to keep the performance within the desired level. EnBW developed possibilities in the middle of 1990 to increase the lifetime of catalysts and so to save working costs of plant dramatically. Furthermore proper catalyst management is the base for quick decisions, for example an in-situ regeneration.

First Operational Experience with the Modern 70-MW-Gasturbine V 64.3 A

J. Fricke, and M. Pauls

Experiences with the modern ring-burning-chamber gas turbine V 64.3 A are discussed. In Hannover and in Duesseldorf each one of this gas turbine type is in operation since 1998 and 1999. At both locations the gas turbine is in operation in a combined GuD-cycle process. Both machines are in operation with commercial success now.

Developing Boiler Concepts as Integrated Units

K. Sørensen, Th. Condra, and N. Houbak

With the objective of being able to optimize the design and operation of steam boiler concepts Aalborg Industries A/S together with Aalborg University, Institute of Energy Technology has carried out a development project paying special attention to the boiler concept as an integrated unit - consisting of pressure part, burner and control system. The Technical University of Denmark, MEK - Energy Engineering Section has participated in the modelling process. The project has included static and dynamic modelling of the boiler concept.

Damage in a 160 MW Gas Turbine - Plastic Deformation of Integrated Shroud Segments

H. Gebert, D. Kodim, M. Freimark, K. Schippers, and M. Grözinger

Four type ABB GT13E2 gas turbines are in operation in Germany. A nearly identical mounting concept of the KA-13E2-2 combined-cycle plant comprising two gas turbines and a steam turbine was applied by contractors ABB, Mannheim, for Bewag in Berlin in 1996 and for RWE in Ludwigshafen/BASF in 1997. Routine inspections and operational audits of all four gas turbines were scheduled for 2002 in accordance with their respective number of operating hours.

Evolution of Gas Turbines for Compressed Air Energy Storage

I. Tuschy, R. Althaus , R. Gerdes, and P. Keller-Sornig

Changing power generation structures in deregulated electricity markets have made peak power generation and possibilities to balance fluctuations in supply and demand of electricity more attractive again. These are typical fields of application for simple cycle gas turbines or large-scale energy storage systems. In contrast to conventional thermal power plants the latter are not just converting fuel into electricity. Storage systems use energy stored in periods of low electricity demand for power generation when the demand is high. Gas turbine technology, however, can also be utilised for energy storage if applied in so-called compressed air energy storage plants.

Increase of Life-Cycle of FDG - Components by Use of Highly Corrosion Resistant Alloys

P. Dierschke, V. Wahl, and R. Streib

To minimize sulphur dioxide emissions from power stations and waste incineration plants, exhaust gases are cleaned in flue-gas desulphurisation (FGD) plants, usually by wet scrubbing with limestone slurry. High-alloyed metallic materials offer advantages for the construction and operation of flue-gas desulphurisation plants. They retain outstanding corrosion resistance even at high temperatures, have excellent processing properties for easy welding and repair, and are non-combustible and eco-friendly, thanks to 100 per cent recyclability.
