Ingersoll Rand serves up PowerSource range of 50 cycle generators

Ingersoll Rand has launched its PowerSource range of 50 cycle generators. The new PowerSource range is a highly engineered line of 12 mobile and portable generator models with prime outputs at rated speed from 10 kVA to 500 kVA.

The generators are equipped with advanced state-of-the-art, stage 2 engines that ensure the optimum mix of performance, fuel economy and low emissions.

The Ingersoll Rand E series range of portable compressors includes the new 7/20E model, the most compact compressor in the 2 m3/min class with a tow weight of less than 500 kg.

The E Series demonstrates a commitment to protecting the environment and offers the option of a ‘bunded base’, providing full containment to ensure that all operating fluids (fuel, oil and water) stay within the compressor.

The new IR20BV pneumatic breaker extends the Ingersoll Rand breaker range to five models. All Ingersoll Rand breakers offer high power output and performance with low vibration levels.

In addition, the low air consumption of the breakers means they are economical to operate. With a weight of 20.8 kg, the IR20BV breaker fills the gap between the current IR15BV and IR25BV models. The power output of the IR20BV breaker is 50 J, and it has an impact frequency of around 1320 bpm.

Twenty-up for Wärtsilä heavy fuel oil engine

Wärtsilä Corporation has introduced a 20-cylinder engine for power plant installations that burn heavy fuel oil.

The 20V46F develops 23 000 kW at 600 rpm, suitable for electricity generation at 50 Hz or 60 Hz. It offers more value for money with lower life-cycle costs as it produces more power and fewer emissions than the existing 18-cylinder 46 engine, while maintaining high energy efficiency.

Per cylinder, the 20V46F develops 1150 kW at 50 Hz or 60 Hz at 600 rpm compared with 975 kW from the 18V46 at 50 Hz/500 rpm or 60 Hz/514 rpm.

The 20V46F’s nitrogen oxides (NOx) emissions are low, down to 710ppm at 15 per cent oxygen, which is the required level in India today – currently the most stringent in the the world. The 20V46F will also be able to comply with the World Bank environmental requirements, which are becoming increasingly tighter.

However, as it is a known fact that reducing NOx emissions has an adverse impact on fuel consumption, the Wärtsilä 20V46F has features that enable the fuel consumption to be optimized while meeting the required NOx emission levels. Additionally, the engine can minimize fuel consumption adaptively according to prevailing ambient conditions.

The complete generating set measures 21 m in length with an extreme width of 6.3 m and height of 6.2 m above the underside of the baseframe. Its total weight is 413 tonnes. It can be dismantled into three units to enable separate transport to site: the engine with baseframe, generator with baseframe and the turbocharger module.

Wärtsilä is aiming the 20V46F at those power plant markets which today still employ liquid fuels and require new, higher output generating plants with lower lifecycle costs and smaller emissions. Despite the focus of many power plant markets on gas, there are many strong markets for heavy fuels, such as Brazilian hydropower backup plants and African baseload plants.

The first engines are due to be shipped in 2009.
