The Volvo Penta TAD1350 series is claimed by the Swedish firm to be very reliable and durable, and is manufactured in one of the world’s most advanced and quality-assured plants. The new TAD1350 series has a displacement of 12.8 litres and comes in three versions: TAD1350GE, TAD1351GE and TAD1352GE with power outputs ranging from 250 kW to 350 kW. The new engines were launched at the POWER-GEN International industry event in New Orleans, LA, USA, which opened on 11 December 2007.

The TAD1350 series is manufactured by the Volvo Group, the world’s largest manufacturer of heavy-duty diesel engines for commercial use. The TAD1350 series has the same basic design that is also successfully used in trucks and construction machinery. No less than 100 000 units are produced each year in highly automated plants with rigorous quality programmes.

Extensive field-testing of the TAD1350 series has been carried out in some of the world’s toughest environments, where the engines have been used to deliver 24/7 prime power and as mobile units for stand-by power. Outstanding results were achieved showing low fuel consumption and high reliability resulting in minimal maintenance requirements.

Cooling is designed for operation in hot climates with piston cooling and highly efficient radiator and charge-air cooler package.

Extensive research in the area of internal combustion has enabled Volvo to develop a combustion chamber that fully optimizes fuel consumption. This is combined with EMS 2, Volvo Penta’s electronic control system that manages unit injectors and turbo charger, to provide low specific fuel consumption, thus reducing cost per kWh.

High fuel efficiency also means low overall emissions. The TAD1350 series satisfies the toughest existing emissions requirements, EPA/CARB Tier 3. Closed crankcase ventilation is available as an option.

The wide range of optional equipment available and the many features, such as high air filter position and the compact design of the new engine, simplify installation. The EMS 2 electronic management system makes the engine an intelligent part of the machine in which it is installed, and enables genset manufacturers to integrate all electronics into one unified system. Stand-alone operation is equally easy.

The new TAD1350 series shares many features with sister engines in the Volvo Penta genset range, contributing to ease of installation and service. Furthermore, the new series can à‚— as with all Volvo Penta’s electronically controlled engines à‚— be connected to VODIA, an easy-to-use service tool for testing, troubleshooting and diagnosis. Volvo Penta is part of the Volvo Group.

These units will serve the peak power loads in the southern Nevada territory, which includes Las Vegas and adjoining communities. Each 60 MW Brush turbo generator will be driven by two Pratt and Whitney FT8 gas turbines in a double-ended Swiftpac configuration.

The first 400 MW are scheduled for start up prior to the summer peak of 2008 with the remaining 200 MW being brought on line soon thereafter. The Brush scope of supply to Pratt & Whitney for the Nevada Power project also included the Brush Prismic model A32 excitation controllers and the generator lubrication system. More than 150 generators are on order or have been supplied for FT8 electric power generation duty.

Each factory has been designated as an FKI Centre of Excellence for the design and manufacture of 2 and 4 pole high voltage generators, synchronous motors and power management systems.

Rolls-Royce wins contracts to power Rome and Milan airports to self-sufficiency

Two of Italy’s major international airports – Fiumicino in Rome and Malpensa in Milan – are set to achieve energy self-sufficiency through new Rolls-Royce power plants.

At Malpensa, Rolls-Royce will supply a second 25 MW industrial RB211 gas turbine to power an environmentally-friendly electrical generating plant being constructed by the Swiss power systems packager Turbomach.

It will be installed alongside an existing RB211 combined-cycle unit to supply the Italian airport with electrical energy, as well as thermal energy, which will be used for air conditioning in the airport terminals.

Fiumicino will have three Rolls-Royce natural gas fuelled Bergen B-gas engines running alongside the current electrical supply network, considerably reducing costs and reducing the environmental impact by cutting NOx. They will supply the Rome airport with its electrical energy, the waste heat from the engines being used as thermal energy (superheated water) for air conditioning in the airport terminals during the summer months and for internal heating requirements during the winter.

Giuseppe Ciongoli, the regional director for Rolls-Royce in Italy, said: “The operators of Rome and Milan airports have selected the best option for their individual needs to enable their airports to operate successfully and safely. We are in a unique position in Rolls-Royce, being able to supply customers with the choice of either gas engines or gas turbines.

“Each year, there are hundreds of take-offs and landings by Rolls-Royce powered aircraft at Rome and Milan, so it will be very satisfying to know that we are also helping their safe arrival and departure by providing the power for vital and essential services on the ground”.

Continuous expansion programmes at both Fiumicino and Malpensa has resulted in the need for an energy production plants providing total self-sufficiency of the airports from outside sources. The new Rolls-Royce powered plants, which enter service in 2008, will be capable of providing the additional energy required to meet the increase in passenger numbers.

There is also a requirement for the energy to be produced in a way that benefits the environment. The efficiency of the both the RB211 gas turbine and the Bergen B-gas engines results in a substantial reduction in the level of emissions released to the atmosphere and in energy savings because of the reduced amount of fuel used compared to other forms of generating plant.

Red dawn for Jenbacher’s coal mine methane gensets

Four of GE Energy’s ecomagination-certified Jenbacher coal mine methane gas engines are generating electricity at a power plant in Shentangzui, Shanxi Province in northern China as the country expands its installation of distributed power systems to address its pressing energy requirements

The project ties in with the country’s national energy Clean Development Mechanism (CDM) based on certified emissions reduction (CER) credits trading. The power generated by the Jenbacher units will be sold to the regional grid, able to serve the electricity requirements of about 97 000 Chinese homes in that region.

Unlike the typical coal mine methane power plant built at a given mine site, for this new project owned by Shanxi Yang Quan Coal Industry Group the methane is extracted from an active coal mine and then delivered via pumps, storage tanks and pipelines over a distance of several kilometres to the company’s Shentangzui Power Plant in the prefecture-level city of Yang Quan, located 100 km north of Taiyuan city, capital of Shanxi Province à‚— one of the leading coal-producing regions in China.

The new Shentangzui power plant features four of Jenbacher’s JGS 620 GS-S.L. engines, with an electrical output of 3.044 MW each and an electrical efficiency of 40.6 per cent.

The generator sets were manufactured at GE’s gas engine headquarters and manufacturing centre in Jenbach, Austria. In addition to the generator sets, GE also provided power plant auxiliary equipment to its local authorized distributor for Jenbacher gas engines, Jebsen & Co. Ltd. The turnkey equipment supply contract for this power plant project à‚— including the coal mine gas pre-treatment and master control system à‚— was awarded to Jebsen & Company Limited in 2006.

By capturing and utilizing the coal mine methane gas à‚— a potent greenhouse gas and available energy source in the mining industry à‚— for power generation with Jenbacher gas engines, less of the gas has to be vented into the atmosphere.

In contrast to the dominant method of local power production à‚— coal fired plants à‚— utilizing this “free” waste gas for power generation will contribute to the Chinese government’s sustainable development goals for the region à‚— including improved energy security and a more circular economy, a model that effectively balances economic development with environmental and resources protection.

Installation of the Jenbacher engines in Yang Quan was completed at the site in May 2007, and start up and commissioning conducted by GE’s Jenbacher business in August 2007.

“Given China’s role as the world’s leading coal-producing country, we are pleased to cooperate with Shanxi Yang Quan Coal Industry Group on this milestone project between our companies as China continues its efforts on curtailing industrial emissions by increasing the utilization of alternative energy sources, including methane gas from active coal mines,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher gas engines division.

GE’s Jenbacher coal mine methane gas engines are popular in coal-producing countries, including in China, Australia and throughout Europe. GE’s technology generates power with existing mine gas and lowers industrial emissions levels thereby lowering operating costs.

Numerous GE Energy products, including GE’s coal mine gas and biogas engines, are certified under ecomagination, GE’s corporate-wide initiative to bring to market new technologies that will help customers meet pressing environmental challenges.

Jenbacher engines cover an output range of 0.25 to 3 MW, expanding up to 4 MW with its first 24-cylinder J624 GS engine, which is scheduled to go into serial production in 2009.
