ORLANDO -- Siemens has reached yet another milestone in its journey to realize the many benefits of additive manufacturing (AM) and to lead the development of this innovative technology in the power generation industry. This time the company has successfully 3D-printed and engine tested a dry low emission (DLE) pre-mixer for the SGT-A05 aeroderivative gas turbine, with the impressive results showing a potential for significant reductions in CO emissions. This achievement further solidifies Siemens’ position as one of the world’s leading developers of innovative additive manufacturing techniques and uses in the energy industry.

"This is another excellent example of how additive manufacturing is revolutionizing our industry, delivering measurable benefits and real value to our customers, particularly as they look to further reduce emissions to meet environmental targets," said Vladimir Navrotsky, Chief Technology Officer for Siemens Power Generation Services, Distributed Generation. "Our achievements using AM are paving the way for greater agility in the design, manufacturing and maintenance of power generation components."

The achievements resulting from using AM to manufacture this particular gas turbine component are significant. From concept to engine test, the development took only seven months, which is impressive for a component that requires such tight tolerances and works in high load and temperature. The DLE pre-mixer is highly complex with over 20 parts involved in the casting and assembly using traditional manufacturing methods. By utilizing Siemens qualified nickel super alloys as the AM printing material, the 3D-printed component requires only two parts and lead time is reduced by approximately 70 percent. 3D-printing of the DLE pre-mixer allows Siemens to simplify complexity in the production process, reduce external dependencies in the supply chain, and improves the geometry of the component, thus allowing a better fuel-air mix.

First engine testing of the AM-manufactured DLE pre-mixer, which was 3-D printed in Siemens' AM center of competence in Finspang, Sweden, was recently completed and the data received is promising. It showed no start issues, all fuel transitions were accomplished successfully without any controls modifications required, there were no combustion dynamics or noise, measurable CO emissions reductions were realized and full power was achieved. These positive results reaffirm Siemens commitment to continuing to advance toward serial production of highly complex components, such as this one, using AM.

Siemens' DLE solution for the SGT-A05 gas turbine reduces emissions through advanced lean burn combustion technology, eliminating the need for water injection. The DLE conversion reduces customers' operating costs associated with water treatment. Application of DLE does not compromise the high dynamic loading response of this aeroderivative engine model. More than 120 engines are successfully utilizing DLE technology to reduce NOx and CO emissions with 3.9 million operating hours accumulated (as of February 2018). ''And now, with AM technology we have an opportunity to go even further with emissions reduction for DLE combustion," said Douglas Willham, Siemens Director of Engineering for the SGT-A05.

Last year, Siemens finished its first full-load engine tests for gas turbine blades completely designed and produced using AM technology. Earlier this year, the company 3D-printed and installed into customer's equipment its first replacement part for an industrial steam turbine. In early 2017, Siemens achieved the first successful commercial installation and continuing safe operation of a 3D-printed part in a nuclear power plant - an impeller for a fire protection pump that is in commercial operation. Siemens accumulated more than 30,000 hour of successful commercial operation for SGT-800 burners repaired with AM technology and for SGT-750 burner swirls manufactured by AM. All these combustor components are running in a very high load and temperature environment.

YOKOHAMA, Japan -- Mitsubishi Hitachi Power Systems, Ltd. (MHPS) has received an order for two sets of steam turbine power generation systems for Nghi Son-2 thermal power project in Thanh Hoa province, Northern Vietnam, led by Marubeni Corporation and Korea Electric Power Company (KEPCO). The new plant will have a total generation capacity of 1,330 megawatts (MW), and will help to drive Vietnam's economic growth and enhance its global competitiveness. The plant is due to be completed and commence operations in 2022.

Nghi Son-2 is being built in the Nghi Son Economic Zone, approximately 200 kilometers south of Hanoi. The project is operated by a special purpose company jointly financed by Marubeni and KEPCO. MHPS received the new order through Korea's Doosan Heavy Industries & Construction, which has been subcontracted by the special purpose company to carry out engineering and procurement.

For Nghi Son-2 project, MHPS will also provide two generators and ancillary equipment in addition to two high-efficiency steam turbines.

Under Vietnam's Revised Power Development Plan VII (PDP 7), announced by the Government in 2016, the country is planning to build new thermal power plants with a total capacity of approximately 55,000 MW between 2016 and 2030. PDP 7 calls for infrastructure facilities of outstanding quality and environmental protection, with a focus on high-efficiency thermal power plants. The latest order continues the trend and highlights MHPS' strong reputation and proven track record in Vietnam.

Going forward, MHPS will continue to provide thermal power generation systems that respond to Vietnam's robust power demand through MHPS Representative Office in Hanoi. MHPS will contribute to environmental conservation by advancing low-carbon energy with high-efficiency power generation systems.

VAN NUYS, Calif. -- Capstone Turbine Corp. has secured an order for a C1000 Signature Series microturbine and a C600 Signature Series microturbine for a luxury residential and commercial development in South Korea. The development will operate as a lifestyle solution which will include residential, hotel, commercial, and leisure facilities.

"This order builds further momentum in the energy efficiency market," said Darren Jamison, President and Chief Executive Officer of Capstone. "During the first quarter of fiscal 2019, Capstone received new product orders from 13 different distributors in 11 countries, and in the first six weeks of the second quarter, we have already received 14 new orders from 10 different distributors in 7 countries. These countries include the United States, Italy, Germany, China, Russia, Iraq and now South Korea as we continue to diversify both our market verticals and geographies."

The natural gas-fueled microturbines will be installed in a combined heat and power (CHP) application in one of South Korea’s largest cities. The configuration will provide high electrical and thermal power generation for the over 35,000-square-meter facility. With an overall efficiency of approximately 80 percent, the investment will significantly reduce the customer’s payback period.

Decision makers looked at various technologies and options for the new development and ultimately chose Capstone microturbines as the ideal solution for the new project. The customer is expected to save 50 percent on their energy costs on an annual basis. The project will also incorporate Capstone’s new state-of-the-art PowerSync MultiMaster controller. The PowerSync MultiMaster will coordinate outputs from the C1000 and C600 microturbines so that they operate as a single power plant. The PowerSync product utilizes a self-healing ring communications topology for controlling each microturbine, which provides for high system availability.
