Improving power plant
energy efficiency

Improved profitability and reduced emissions

With up-to-date equipment, well-planned maintenance and skilled operation, a power plant’s energy efficiency can be kept on a high level throughout its lifecycle. Customized lifecycle upgrades can considerably increase energy efficiency, improving the installation’s performance. A boost in energy efficiency also decreases emissions.

Combined cycle upgrade

The solution minimises the ecological footprint and maximises the efficiency of simple cycle power plants by up to 10%, by producing additional electricity using waste energy from exhaust gas.

Wärtsilä engine performance optimisation

Engine performance upgrades are often based on the latest, state-of-the-art turbocharger with improved efficiency. Higher pressure ratio capability combined with optimum engine settings such as advanced valve timing, improves engine efficiency, while the optimised combustion reduces exhaust gas emissions. Combining engine performance optimisation with a major service interval is most cost efficient.
    Performance optimisation with turbocharger upgrade for Wärtsilä 38 & 46

    An upgrade package involving a turbocharger exchange to improve engine output and increase certainty of operation.

    In most cases, at 50,000 hour intervals, turbochargers require a major overhaul and the rotating parts need to be replaced. However, instead of carrying out this extensive maintenance work, it can make more sense to utilize Wärtsilä’s upgrade package and exchange the turbocharger to take advantage of the latest generation technology.

    The benefits of the efficiency improvements are considerable. A reduction in fuel consumption of up to 4 percent can be achieved, thanks to the optimised engine tuning and higher boost.

    Pre-chamber upgrade for Wärtsilä 34SG

    The pre-chamber of the Wärtsilä 34SG engine is optimized by using advanced three-dimensional, computerized fluid dynamics.

    The pre-chamber is the ignition source for the main fuel charge, and is thus one of the essential components of a lean-burn spark-ignited gas engine. The advantages of the new pre-chamber include more stable combustion, which results in a more stable load and improved overall efficiency.
