Siemens appoints new CEOs for wind and oil & gas divisions

DOE-sponsored research helps improve gas turbine performance

An innovative airfoil manufacturing technology that promises to improve the performance of state-of-the-art gas turbines has been commercialized through research sponsored by the U.S. Department of Energy (DOE). The technology – which is expected to contribute to cleaner, more reliable and affordable domestic energy production as well as creating new high-tech manufacturing jobs – was licensed by Siemens Energy Inc. (Orlando, Fla.) in 2011.

How to combat performance degradation in turbines

At the 2013 Turbo Expo on turbine degradation, Rainer Kurz, Manager of Systems Analysis at Solar Turbines (and a Myth Buster columnist for Turbomachinery International), delivered an opening lecture outlining the various environmental conditions that can lead to fouling, corrosion and performance degradation. This includes viscous hydrocarbons from flares and exhausts, dust, sand, cement dust, shot blast, iron oxides, salt crystals as well as cyclic wet/dry conditions.

PowerGen meet underscores the need for cooperation among European nations

Siemens to supply CCGT for new 60 MW plant in Germany

Siemens, Evonik and E.ON recently signed contracts to build a new combined cycle gas turbine (CCGT) power plant for energy supply to Marl Chemical Park, Evonik’s largest production facility. For this joint project, Siemens has agreed to supply the CCGT. Siemens has also been awarded a multi-year service contract to maintain the gas turbine and ensure that it meets high standards for performance, availability and reliability.

Siemens bags order for H-class gas turbine power plant solution in Turkey

Siemens has won the order for supply of a single-shaft power island with H-Class technology for the Samsun Cengiz Enerji combined-cycle power plant in Turkey. The customer, Cengiz Enerji Sanayi ve Ticaret A.S., is an independent power production (IPP) company which will build and operate the plant.

Alstom to access Chinese turbine market with GT13E2 license agreement

Alstom has recently signed a long-term agreement with Harbin Turbine (HTC) to license its GT13E2 gas turbine for manufacture, assembly and sales in China. As per the agreement, HTC will manufacture and assemble the GT13E2 gas turbine in China, while Alstom will supply some of the critical components.

Through the deal Alstom is expecting to gain better access in the Chinese market and supply its GT13E2 E-class turbine through HTC. The two companies are also expected to set up a service joint venture to serve the Chinese GT13E2 customers.

Monitoring shaft end seals in condensing turbines

Most steam turbine vendors use a vacuum gland condenser system to ensure that air enters the last section of the steam seal, thus preventing steam from entering the bearing bracket and contaminating the oil system.

Siemens F-class turbines begin commercial operation in California

Siemens recently supplied four power 180 MW Siemens simple cycle SGT6-5000F gas turbine units to power American operator NRG Energy's gas-fired Marsh Landing Generating Station (720 MW), located in Antioch, California, 40 miles from San Francisco. The 720 MW gas-fired plant, a Brownfield development, began commercial operation supplying the California grid on May 1.
