Technology & Innovation

Alstom has developed a new nozzle design for gas turbines and is getting ready to put it to production. "We started to use them in production, now that we've solved an initial problem with nozzle life time," Sebastian Mihm, coating engineer at Alstom said today.

Robustness and increased thickness of thermal barrier coatings (TBC) of industrial gas turbines  is 'key' as the industry aims to ramp up firing temperatures and pressure ratio to boost turbine performance. "We need to spend more R&D money on TBC process robustness," Matthias Oechsner, professor for materials technology at the technical university of Darmstadt, Germany, told an industry forum in Nice today.

Iran is gearing up to produce 'home-made' gas turbines. "A contract has been signed with Oil Turbo-Compressor Company to make a 100% indigenous [gas] turbine," Iran's deputy oil minister, Mohammad-Reza Moqaddam, said on Monday.

Mechanical and plant engineering group Dürr and the German Aerospace Center (DLR) have teamed up to further develop micro gas turbine technology. Dürr set up a new Clean Technology Systems division with the aim of achieving sales of over € 200 million by 2015.

General Electric's (GE) global fleet of 47 heavy duty gas turbines have achieved an industry milestone, operating more than 2 million fired hours on low British thermal unit (BTU) fuels.

Guangxi Yuchai Machinery Company Ltd (GYMCL), a subsidiary of China Yuchai International, said today it is developing a new line of natural gas-powered engines to complement GYMCL's line of diesel engines used in power generators and marine engines.

Alstom Power has launched a GT13E2 gas turbine upgrade, offering over 200 MW power, an additional 10% of electricity output when compared to the earlier rating. "The higher output has an increased efficiency of 38% - the best in this segment of gas turbines," Michael Ladwig, Director, Marketing & Product Management at Alstom's Gas Business said at a web conference today.

Power generator can improve safety, reliability and efficiency by installing multifunctional wireless networks in power plants, a white paper published by Honeywell Process Solution shows.

General Electric's (GE) TM2500+ aeroderivative gas turbine has received ecomagination qualification for its ability to help power cities and industries during emergency power challenges. "The TM2500+ is a workhorse in the global aeroderivative mobile fleet," GE said.

Alstom has optimized the operation concept of the KA26 combined cycle power plant for fast start-up as the French gas turbine manufacturer is focusing on the operational flexibility of its gas turbines.

“Operational flexibility is not just having a high ramp rate, rather it’s a combination of start-up and shut down times, ramp rates and efficiency at part load operations,” Michael Ladwig, Director of Marketing and Product Management for Alstom's Global Gas Business told ‘Gas-to-Power Journal’ in an interview.

GE Energy's Industrial Solutions business has won the 2011 North America Supplier of the Year award from Gexpro, a part of Rexel Holdings, U.S. 

HOCHTIEF Energy Management and its partners, Augsburger Leasing and 2G-Energietechnik, have developed a full service solution which allows the flexible deployment of combined heat and power (CHP) units built in container style.

Siemens has received the German Industry's Innovation Award for developing the H-Class gas turbine (SGT5-8000) with a world record efficiency of 60.75 percent. Including the test phase, development of the SGT5-8000H gas turbine "lasted a good 10 years", with investments costs at approximately one half billion euros, the Erlangen-based turbine manufacturer said.  

Siemens and RWE are gearing up to expand a jointly-operated virtual power plant (VPP) with additional energy sources. In 2012, RWE plans to market about 20 MW of electricity and the cap will be increased tenfold to about 200 MW by 2015, the companies said today.

RWE sees fossil power plants as vital partners of renewable energy sources. Quick ramp rates are vital to provide flexible backup capacity and gas-fired plants still in the lead, outperforming coal-plants. "It takes RWE only 18 minutes to ramp the output of its 876 MW Lingen combined cycle gas turbine plant up or down by 600 MW," a RWE spokesman told Gas-to-Power Journal.
