Wärtsilä tunes in
The 18V34SG sets can balance between electrical and thermal output
An Indian glass shell company seeking to double its output and become one of the world’s largest in its field has contracted Wärtsilä to supply an 18 MW gas fuelled captive power plant.
Videocon Narmada Glass in Bharuch is already India’s largest manufacturer of glass shells for colour television tubes and it is confident that the three 18V34SG generating sets it has purchased will power its growth plans.
Each of the gensets produces 6 MW and has an output at 11 kV. They were selected to provide the factory’s new production capacity with electrical power and process heat.
LCH powers charity’s Tsunami relief mission
Members of the relief team test the generator before it is sent to Indonesia
Glasgow based LCH Generators and Scottish Water have combined to donate a 415 V, 60 kVA three phase generator to power a water purification plant together with two water tanks for victims of the Asian tsunami disaster.
Built by Babcock, the reverse osmosis plant is a self contained unit housed in a standard 20 foot ISO container. Designed to turn brackish water into clean fresh water for drinking, the plant is being shipped to the Indonesian region of Banda Aceh by Blythswood Care, an international aid charity.
Centinel stands guard
The Centinel was formerly only available as a new engine option
Cummins’ advanced engine oil management system, Centinel, is now available as an aftermarket kit for the QSK, QSK19, QSK45 and QSK60 engines rated between 261-2238 kW.
The Centinel enables operators to extend oil change intervals to up to 4000 hours, removing 15-20 oil changes, depending on the platform. Integrating with Cummins electronics, Centinel blends the lube oil with fuel prior to engine combustion and adjusts the burn rate based on the equipment load factor. The system is available with reserve tanks for continuous oil replenishment.
Further maintenance interval extensions can be achieved with the addition of the Eliminator oil filtration system, a full flow and centrifugal system. By eliminating the need to replace and dispose of used oil filters, lube system maintenance costs are reduced by as much as 90 per cent.
The Centinel aftermarket kit can be purchased and installed at any Cummins distributor location.
Figure 3. Aggreko’s new fleet stand ready for action
Aggreko has introduced a new line of 1.5 MW diesel electric generators to the US market, designed to handle loads ranging from large events to baseload power generation.
Featuring ISO-size containers the generators also offer synchronizing and load sharing capabilties. Aggreko say the generators are its most advanced attempt at creating environmentally friendly, quiet and efficient contained generators.
The company has stated that the 1.5 MW range is available for rent to its industrial, commercial and event/entertainment customers.
The TAD940VE offers four placement alternatives for the turbo compressor
Volvo Penta has replaced its 9 litre industrial engine range with a new engine that is fitted with EMS 2, a new electronic control system that aims to optimize performance and fuel efficiency.
The new 9.4 litre engine is available with power outputs ranging between 190 and 280 kW. Compared to its predecessor, the new engine delivers 22 per cent more torque and 20 per cent more power.
One of the factors behind the new engine’s improved performance is the Engine Monitoring System 2. The system monitors and regulates the engine components, including the fuel needs up to 100 times per second. Volvo Penta state that by controlling injection levels and timing through valves in the unit injectors, the engine always receives the amount of fuel that operating conditions demand.
As the new engine is electronically controlled, it can be connected to VOIDA, the compact service tool tests, troubleshoots and diagnoses.
XL lubricates for long life power
Shell Lubricants have developed a new long life gas engine oil for use in high output 4 stroke engines.
Mysella XL, a low ash oil, has been formulated to lubricate modern gas engines used in power generation, co-generation, gas collection and transmission applications. Shell state that field trials with companies such as Rolls-Royce, Waukesha and MWM Deutz, have proven that Mysella XL resists oxidation and nitration, increase of viscosity and the formation of harmful acids.
The lubricant can help minimize engine wear, lubricate hot pistons without forming excessive deposits in ring grooves and control ash deposits in valves and spark plugs. All aiding the prevention of problems such as knocking.
WEG waters San Diego
WEG’s 1865 kW motors are employed at the Olivenhain dam
The San Diego Water Authority is using WEG’s MV motors to power the first part of its $827m emergency stock project that it hopes will secure the area’s water supply.
The $200m Olivenhain dam and reservoir project is fed by pumps driven by WEG H-line 60Hz motors that generate 1865 kW.
Because the region around San Diego is essentially dry, water needs to be pumped from remote sources both for domestic and industrial use. If there are any shortfalls in this process then the result is huge problems and losses for the whole area. The dam will not block off a stream or river, instead it will box off a canyon and be filled with 7.8 billion gallons of water.
Perkins adds another
Perkins has introduced a new addition to its Sabre engine range. The 415GM extends the lower end of the Sabre line up to seven models with net power outputs spanning from 13.5 kW to 161 kW.
GE launches engine for gas compression
Jenbacher gas mechanical drive engine in Louisiana
GE Energy has introduced its first Jenbacher gas mechanical drive engine for use in gas compression. The 12 cylinder J312 GMD engine, rated at 676 brake horsepower and 1800 rpm, is driving a GE A354 three stage compressor.
The J312 comes equipped with the DIA.NE XT monitoring system, which interfaces with compressor controls and provides air/fuel ratio control to help maintain NOx emissions without using oxygen sensors.
GE’s Jenbacher gas engines range in output from 0.25 to 3 MW and run on natural gas as well as gases created from biomass, landfills, coal mines, sewage and industrial wastes.
Rypos filters particular about particulate
Continuous monitoring maintains back pressure
A diesel particulate filter (DPF) system that traps up to 90 per cent of soot while using less than 1 per cent of the engines output has been developed by Rypos.
The DPF is controlled by a microprocessor that monitors operation and periodically, as required, transmits an electric current through a filter, which then acts as a heating element. A dedicated power source then provides the required electrical current to heat the filter element to the temperature required to burn soot.
The sintered metal fibre filter has been designed to be electrically conductive with high soot holding capacity and is capable of capturing the very fine particles in the exhaust system.
The Rypos DPF package includes filter housing, an electrical control circuit and filter cartridges. It is fully automatic, with no downtime and can be adapted for use with 50 kW to 2000 kW diesel generators that need not have had a diesel oxidation catalyst fitted.
FEV and NREL develop diesel of the future
The layout of the FEV system
FEV is working on a US National Renewable Energy Laboratory programme to develop a new diesel control system that will meet the US emissions requirements that will come into effect in 2007.
To put the emission control system through its paces, FEV used an advanced high pressure common rail fuel injection system, low sulphur diesel fuel, NOx absorber catalysts and diesel particulate filters on an Audi A4. Built primarily from production parts the test engine was also fitted with a special cylinder head and piston design developed to reduce emissions. These measures were designed to test the systems impact on engine performance and durability.
Initital results have indicated that the levels being introduced can be met and the company are confident that their concept can deliver with a fuel economy penalty of less than five per cent. The next phase of the programme will test the long term aging performance of the system.
