Tognum to supply emergency standby gensets to E.ON Kernkraft

Tognum, the specialist for propulsion and power solutions has won a contract to supply E.ON Kernkraft GmbH with two emergency standby systems to the value of around €11m.

The Tognum subsidiary MTU Friedrichshafen GmbH will be delivering the two MTU Onsite Energy gensets to the Bavarian nuclear power plant Isar I at the end of 2011 and the beginning of 2012. The two new emergency standby systems are scheduled to replace their predecessors in mid-2012.

“Over the coming years we will be steadily expanding our business with systems for the important area of emergency power supply in nuclear power plants,” explained Christof von Branconi, Tognum COO with responsibility for the business unit Onsite Energy & Components. “The demand comes partly from projects for the renewal of existing plants and partly from newbuilds.”

There are currently more than 400 nuclear power plant blocks in operation throughout the world and estimates foresee around an additional 170 coming on line by 2020.

The gensets are based on MTU Model 12V 956 TB33 and 16V 956 TB33 engines producing 4300 kVA and 5730 kVA respectively. In case of a grid outage, the emergency standby gensets can take over the entire power supply no more than seconds after start-up.

The company has been working with this customer for more than 30 years now. MTU supplied the emergency standby gensets when the nuclear power plant Isar I was built.

The Tognum Group is the only German manufacturer to have developed a specially tailored engine program compliant with the stringent demands which the German Nuclear Safety Standards Committee (KTA) places on diesel-powered emergency power generation facilities in nuclear power stations.

GE gas engine technology to provide cleaner energy through reduced emissions and increased efficiency

à‚ 

Helping to provide cleaner energy, the first GE Jenbacher gas engine for district heating in Spain has entered commercial operation at UR BEROA S COOP, a cooperative society.

UR BEROA S COOP. provides district heating for approximately 600 houses in the up-market residential area of San Sebastian (Bidebieta). By using natural gas to provide heating, this project will help reduce CO2 emissions by roughly 1200 tonnes per year.

UR BEROA S COOP. is a cooperative society formed by the neighboring community of Bidebieta II in San Sebastiàƒ¡n (Guipàƒºzcoa). Formed in 1985, the neighbors, who are made up of 584 associates, manage this community.

The plant includes a central building with one of GE’s Jenbacher gas engines producing hot water, which is distributed to seven sub-centrals, each with aa exchanger for heat and another for sanitary hot water. From there, it is distributed to the houses. Each sub-central corresponds to a group of houses, and the whole system is remotely managed and tailored to the needs of each area.

“The need for a more reliable, cost-effective and secure supply of energy, combined with growing concerns over climate change, have influenced energy policy decisions in recent years. The EU has taken a lead in promoting cogeneration of combined heat and power (CHP) solutions as one of the key strategies to help member nations attain their emissions reduction targets under the Kyoto-E.U. CHP directive,” said Juan Ignacio Sabadie, president of UR BEROA S COOP.

The installation will operate year round to meet the heat demand for all of the houses. GE’s JMS 320 GS-N.L. 1 MW cogeneration system, which began commercial operation in November 2009, is replacing the oil-based system that was previously used for heating at UR BEROA S COOP. The electricity is sold to the grid.

Wärtsilä to deliver its largest power plant project ever with Brazilian plant

à‚ 

Wärtsilä has been awarded a major contract for building a power plant in Brazil. This turnkey contract is valued at close to EUR 200 million and the plant will have an electrical output of 380 MW.

The order is taken into Wärtsilä’s order book during the second quarter 2010. Commercial operation of the power plant is scheduled for January 1, 2012.

This project represents the largest power plant ever built by Wärtsilä anywhere in the world. The order has been placed by Energética Suape II SA, a company jointly owned by CIBE Participaàƒ§àƒ£o SA and Petrobras. An Operations and Maintenance (O&M) contract is also under negotiation between Wärtsilä and the customer.

“The high overall efficiency of the Wärtsilä engines, together with the company’s ability to provide a total power solution, including operation and maintenance if required, were key factors in us selecting Wärtsilä. Furthermore, as Wärtsilä already has a number of large power plants in the area, the company can readily deliver us strong local support,” explains Mr. Wilson Brasil, President of Energética Suape II SA.

The plant will be powered by Wärtsilä 20V46 generating sets, running on heavy fuel oil. The electricity will be fed to the national grid to supplement the country’s primarily hydropower generation, which is subject to seasonal fluctuations. Hydro power accounts for some 90 percent of Brazil’s electricity production. The customer’s specific requirements are for a power plant capable of providing fast response to the changing grid load needs. Wärtsilä’s flexible solution is ideally suited for this kind of application.

The new power plant will be built in the Suape industrial district of the town of Cabo in the province of Pernambuco, North Eastern Brazil. Wärtsilä has delivered or has under construction a total of 22 power plants in Brazil. These power plants, together this new order, will produce a combined generating capacity of more than 2000 MW.

MWM introduces natural gas and biogas genset applications

à‚ 

In addition to the recent expansion of its product range with the new TCG 2020 K genset, MWM from Mannheim, Germany, now wants to increase its presence in the field of complete turnkey systems. In this context, the company has introduced the new MWM container, a highly efficient and economic system designed especially for natural gas and biogas applications.

Especially in the field of biogas, the container represents an overall package consisting of a biogas genset, a standard container, and biogas processing. All components are tuned to each other, and are perfectly aligned for the special requirements of biogas operation. For example, exhaust turbochargers and controlled gas systems designed especially for this application case are used.

The efficiency is substantially improved by optimized chamber spark plugs and special pistons. Moreover, the cooling water and exhaust gas heat exchanger are integrated in the heating circuit. The TA-Luft exhaust gas regulations are complied with, and the requirements for the emission reduction bonus (e.g. for Germany) for limiting formaldehyde by means of active carbon desulphurization, catalysis, gas cool drying and, if necessary, compression, are met.

Depending on the application case, the engines can be adjusted for various natural gas and special gas qualities in addition to biogas. The container can be implemented with the MWM gensets TCG 2016 C (V08, V12, or V 16) and TCG 2020 (12, 16, or 20 cylinders). The main focus is on reliability and advanced efficiency, which are achieved through measures such as the optimized intake duct and combustion chamber, contributing to a 15 per cent reduction in annual fuel costs. Furthermore, improved engine parts enable lubricant savings of up to 50 per cent compared to similar gensets.

The TEM system effectively controls not only the engine, but also the entire plant including the heat from cogeneration. Temperature monitoring for each cylinder and anti-knock control ensure optimum fuel utilization and maximum power output even if the gas composition should fluctuate.

With its standardized container dimensions 3 x 3 m (W x H) including the genset, peripherals, and switchgear, the entire unit is not only extremely compact, but also ensures easy transportation and quick setup on site. If necessary, the container floor can serve as an oil catch pan.

Furthermore, the container is heat and noise insulated, and the slim, smooth wall design enables maximum utilization of the interior space.

The TEM system even allows direct online access to current engine values during operation. Furthermore, all relevant international certifications have been obtained, such as CE, GOST (Russia), and CSA (Canada).

Italian arthur wls from saab gets hgi auxiliary power units

à‚ 

The Italian Army ARTHUR WLS (Weapon Locating System) Radars, delivered by the defence and security company Saab, are to be powered by Harrington Generators International (HGI) compact military auxiliary power units.

HGI and Saab worked closely together to accommodate the power plants into the very restricted space envelope while still ensuring full access for maintenance was possible. To achieve this, the power unit is fitted with slides so that the main assembly can slide out of the vehicle.

“We are delighted to have won this repeat order as it confirms that we provide quality, reliable solutions which meet our customers’ requirements,” said Bryan Harris, managing director of HGI.

The power units have undergone extensive military compliance testing including Mil-Std EMC testing and environmental trials. The units produce 30 KW, 3-phase, 400 V in environments from – 40à‚ºC to + 55à‚ºC and at altitudes up to 3 km above sea level. The design of the units minimizes weight whilst ensuring compliance with the shock, vibration and acoustic specifications.

Saab’s ARTHUR is a transportable medium-range WLS with radar, climate control and power generator integrated on a single all-terrain vehicle. The main components are a C-band doppler radar with phased-array antenna, data processing unit, operator workstations, communication equipment and inertial navigation unit. The ARTHUR system searches for and locates incoming enemy projectiles, providing information about the firing position and point of impact, and can simultaneously direct countermeasures.
