It gives me great pleasure to present the second edition of Power Engineering International’s special Gas & Steam Turbine Directory issue, which as the name suggests focuses on the workhorses of the conventional power industry, namely gas and steam turbines.
As in last year’s edition, we include comprehensive technical specifications supplied by the major global gas and steam turbine OEMs in an easy-to-digest, tabulated format, beginning on p.34, that enables you to make an easy comparison between different machines.
This is followed by a Products and Services section (beginning on p.44), which provides an extensive listing of suppliers to the gas and steam power generation industry. Whether you are looking for something as small as a valve or something much larger, such as a gas turbine, you will find the right supplier listed here.
As always, we hope this will prove an invaluable tool for making the right equipment or services purchasing decision – a key objective of any specifier in these economically constrained times.
The Company Addresses section, which begins on p.52 and completes this year’s directory, comprises an alphabetical listing of companies with their full contact details.
If you spot any errors or omissions in the directory, do not hesitate to contact either myself or my colleague Kelvin Ross (firstname.lastname@example.org). We compile the company information from our own questionnaires, and while we take all possible care to ensure that this is accurate, any constructive feedback is greatly appreciated and will help us ensure the directory continues to provide the most up-to-date information.
Few would dispute that the last 12 months have been an exciting time for gas fired power generation and for the gas turbine sector in particular. We have seen several of the leading manufacturers breaking the much sought after 60 per cent efficiency barrier with their latest gas turbines.
Furthermore, with the changing energy landscape as more renewables are integrated onto our grids, the demand for high-efficiency, high-flexibility power plants as back-up will only grow. This latest generation of gas turbines are also able to provide that degree of operational flexibility – ramping up and down within minutes.
However, the industry should not sit on its laurels. As Christer Björkqvist, managing director of the Brussels-based European Turbine Network, explains, the importance of greater investment in gas turbine R&D should not be under-estimated. Gas turbine technology will play a pivotal role in helping to ensure Europe, and the rest of the world, achieves a low-carbon, reliable and secure energy mix. You can find his interview on p.26.
As mentioned above, the demand for fast-cycling power plants is on the increase. The resulting temperature shifts place enormous stresses on the plant and, more importantly, its components. For a new power plant those concerns are addressed in its design. But what about existing coal and gas plants that are being operated in a start-stop manner? Such rapid thermal cycling can lead to fatigue and fracture of plant components. Can realistic simulation play a role in preventing this, and thereby help to optimise plant cycling and operations? Axel Schulz from Germany’s TÜV NORD believes it can (p.22).
Paul Breeze, a regular contributor to Power Engineering International, explores the industry’s dream for the 50 per cent efficiency steam plant. He examines where the industry is in terms of reaching this goal and finds out that achieving it will take a significant sea-change in technology.
I hope you find our Gas & Steam Turbine Directory both useful and informative.
