The focus in hot section coatings is shifting from temperature to time. "It's all about coating durability," Carol Crowe, aftermarket coatings discipline chief at Pratt & Whitney said today.

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.

Schneider to complete L&T takeover by early 2020

Sept 13 – Venturing into India, Schneider Electric hopes to finalise the Rs 14,000 crore acquisition of Larsen & Toubro's electrical and automation business by early 2020. After the transaction is completed, Schneider will have a 65% stake in L&T, while the remainder will be held by Temasek.

MHI to advice China on energy conservation

Sept 12 – Mitsubishi Heavy Industries Thermal Systems, part of MHI, has set up a joint venture withan affiliate of State Grid Corporation of China (SGCC) to perform technical consulting for energy conservation projects in China. The focus of SGCC lies on building new decentralized power stations, biomass-derived power gensets and energy saving solutions.

Tender extended

Sept 11 – Turkmengas has extended a tender for the overhaul of the gas turbine engines of the NK-12ST and NK-14ST brands. Bidders need to pay to receive the tender documents, and then submit a written application to Turkmenistan’s state gas company.

Gas power units to buffer Germany’s coal exit

Sept 10 – Electricity output of Germany’s fleet of gas-fired power plants has risen to a over 13,5 billion kilowatt-hours in the three months from June to August, Fraunhofer ISE figures show. These productivity gains put CCGTs in pole position to balance supply swings in connection with the German coal exit.

Power of Siberia gas flows to start on Dec 1

Sept 9 – Russian gas supplies to China via the eastern route are going to start on December 1, 2019, Gazprom chairman Alexey Miller told his counterpart at CNPC in Beijing.
