Technology & Innovation

 Japanese utility Tepco Fuel & Power has signed an accord with engineering firm Mitsubishi Hitachi Power Systems (MHPS) to jointly work on improved efficiency for thermal power plants at home and abroad. In focus are improved equipment solutions and O&M services.

Incentives have spurred a surge in biogas production that is injected into the gas transmission network in countries like Germany. However, gas quality and volume of the grid-injected biogas needs to be closely monitored to ensure its computability and safe use as a fuel for power generators. Elster has developed such a monitoring system.

Scientists at Japan's Kyoto University have tested various compositions of molybdenum silicides for use at turbine blades, improving the strength of the material at temperatures around 1,400 degrees Celsius. Research shows that adding tantalum to the composite helps boost material resilience.

Siemens has manufactured and tested what it says is the world’s largest geared compressor rotor for use in the air separation unit of the 4 GW Jazan integrated gasification combined cycle power project. The IGCC, built on behalf of Saudi Aramco, will form part of its refinery and terminal complex on the Red Sea coast.

With its MGT gas turbine series achieving highest efficiency in the 6 MW class, MAN Diesel & Turbo is showcasing its entire product portfolio at this year’s PowerGen Asia in Seoul, Korea. “With a product range that’s unique in the market, MAN Diesel & Turbo is able to provide both gas and diesel engines as well as gas and steam turbines as a one-stop-shop solution”, said Wayne Jones, board member for Global Sales and After Sales.

The world’s largest lithium-ion battery power storage – a 20 MW/80 MWh Tesla Powerpack – will be put in place at SoCal Edison’s Mira Loma substation in an effort to better harness renewable energy sources. California Public Utilities Commission (CPUC) had mandated an accelerated procurement of power storage to counteract energy shortages following the Aliso Canyon gas leak.

Research into thermoacoustic instabilities for gas turbines may allow designers to produce calculations up to ten times faster, according to Camilo Silva, researcher at the Technical University of Munich (TUM). “Results from the adjoint surrogate model (matrix-vector multiplication) were obtained around ten times faster than the method involving the full solution of the eigenvalue problem. The larger the matrix, the larger the difference of computing time between one matrix vector product and one eigenvalue problem,” he told Gas to Power Journal.

In June last year, Siemens launched SPPA-T3000 Cue as the latest release of their instrumentation and control system for power generation. Dr. Dirk Lumma, head of product management for Power Generation Control Systems, explained to Gas to Power Journal that this latest release has evolved under an operator-centric approach.

Analysis of the techno-economic impacts of gas turbine cycles is delivering better understanding of power plant operation and opportunities for the implementation of biogas. “Contrary to previous analyses presented in the literature, the present work shifts the focus from typical gas-turbine performance parameters (SFC, sp. power, etc) to more integral metrics related directly to the economic sustainability of the overall investment,” Dr Ioannis Goulos, researcher at Cranfield University told Gas to Power Journal. 

With its latest generation of gas engines delivering improved performance, engine manufacturer Himoinsa expects growth in its home European market. Manuel Aguilera, gas project manager told Gas to Power Journal: “Our growth will revolve around new business opportunities in Eastern Europe, in France or in the UK, markets in which the demand for gas generator sets is growing at a higher rate.”

CD-adapco has accelerated development efforts for its Internal Combustion Engine (ICE) simulation solutions. The plan is to enhance capabilities in the STAR-CD /es-ice suite of software and facilitate a majority of in-cylinder simulations within the company’s flagship product, STAR-CCM+, by the close of 2017.

The focus in hot section coatings of gas turbines is shifting from temperature to time – so it's all about coating durability, some say. Yet, thickness of thermal barrier coatings (TBC) is still a key issue, as parts of the industry keep pushing for ever-higher firing temperature to boost efficiency rates.

Developer of gas turbine upgrades Powerphase LLC has been issued a new patent from the United States Patent and Trademark Office. The US Patent No. 9,388,737 covers ‘Turbophase’, a technology that solves the problem that gas turbines lose output at high ambient temperatures or elevations.

Sicam A8000 – a combination of power supply, processor, and expansion modules – has been launched by Siemens as a new telecontrol and grid automation system. Employed in substations, it connects distributed renewable power sources and helps balance supply for industry applications or in railway power systems.

AAF International has developed a gas turbine (GT) inlet cooling system which provides fast response to the changing dynamics of gas turbine power generation. High-capacity rotary atomisers on the dirty air side of filters, combined with a control system to finetune the downstream temperature, are key features of its new InstaKool system.
