Alstom, which has installed more than 750
HRSGs globally, and Arabian Bemco, a turnkey contractor and local manufacturer within Saudi Arabia, will each take a 50% stake.
The
HRSGs will be coupled to six SGT6-5000F Siemens gas turbines firing natural gas and oil with commercial operation set to begin in 2017.
In all, the contract will cover the design, manufacture, supply, installation, testing and commissioning works for five F9BE
HRSGs, and include all associated modification of the existing control systems.
It has also carried out two
HRSGs as part of a once-through
HRSG contract for NeM (Netherlands at Occidental Mukhaizna.
"We use more sophisticated and corrosion-resistant metals, typically a variety of stainless steels, to withstand the higher temperatures and pressures, instead of the small amount of stainless we use for industrial
HRSGs," said Bryan Stephan, vice president of sales at Foster Wheeler.
Siemens is supplying a total of twelve gas turbines, five steam turbines, 17 generators and ten
HRSGs and the entire electrical and I&C equipment for the Ras Al-Khair CCPP and seawater desalination plant.
Companies worldwide that in the 1980s and early 1990s had developed open-cycle gas turbine (OCGT) plants, which were seen as quick to develop in jurisdictions hungry for power, are now adding
HRSGs and steam turbines to convert their stations to CCGT mode.
