The Wärtsilä 34DF is a four-stroke multi-fuel engine generating set. It allows instant switching to alternative fuels, should price instability or delivery challenges affect the use of the primary fuel. It operates on the lean burn principle, which reduces peak temperatures and lowers NOx emissions considerably.
The Wärtsilä 34DF engine generating set is extremely reliable as it is based on the wellproven Wärtsilä 32 engine that has a track record from the mid-1990s. The Wärtsilä 34DF features a wide power output range from 5.6 to 9.8 MW, as it is available in 12V, 16V and 20V cylinder configurations. Wärtsilä engine power plants can be delivered both as EPC and Equipment Delivery contracts.
The rapid growth in renewable energy in the UK has increased the need for flexible power to balance the electricity grid. Wärtsilä has worked closely with energy and services company Centrica to provide the changing market with flexible energy, helping tackle the issues created by intermittent renewables and supporting the transition to a low-carbon energy system.
Flexible combined heat and power plant (CHP) in Germany –enabling KMW AG to operate profitably in the increasingly volatile power market and provide climate-friendly district heating to the community.
The state of California is known for its amazing nature and climate. Being home to beautiful beaches, sandy deserts and redwood forests alike, it is hard to find a corner of the planet with comparable natural and climatic diversity. It’s certainly called the Golden State for a reason! But to keep it golden, its inhabitants and regulators are very aware that its fate cannot be left to chance. Climate change is a real threat, and biological degradation could pose a serious risk to an agricultural region that feeds well over 100 million people.
The growing demand for natural gas as fuel and the increasing importance of environmental values in Japan have encouraged investments in gas-fired power generation systems. The green point of view has also contributed to the rise of interest towards trigeneration energy sources.
