Wärtsilä gas power plants

The Wärtsilä GasCube is a complete one-engine power plant, based on the most powerful Wärtsilä 34SG engine, with all the auxiliaries and components needed to make up a working power production unit, providing close to 10 MWe per unit. Several GasCubes can be connected to each other to increase total plant output.

Due to the self contained design, the GasCube is the optimal solution for agile, streamlined and exceptionally cost efficient project execution. The Wärtsilä GasCube consists of a prefabricated building that has the engine and the alternator located on a common baseframe. 

All auxiliaries are located in the modules. The auxiliary module includes a gas regulating unit, the cooling system, an instrument air system and an engine pre-heater. The inlet air module, charge air silencers, exhaust gas system and an auxiliary module are all connected to the genset. The radiators for engine cooling are installed on the roof. The starting air compressor, starting air vessel and the maintenance water tank are installed next to the generating set.

The closed-circuit cooling systems used in the GasCube make it the perfect choice for remote locations or any location in which water is scarce.

All Wärtsilä gas power plants are also designed to give full output and high performance in hot and dry conditions, as well as at high altitudes. New possibilities for Cube placement are opened up by the Cube’s simple interface and small footprint. A typical storage yard of an industrial company, for example, would be more than adequate as a location for this compact solution offering excellent power density.

Benefits:

• High electrical efficiency through minimizing the plant’s own consumption
• Simple and reliable technical solutions
• Compact, pre-engineered design
• Perfect for turnkey (EPC) deliveries even to areas lacking infrastructure

Depending on power plant solution Wärtsilä engines are able to run on a wide selection of fuels, ranging from natural gas to fuel-water emulsions.

Fuels such as crude oil, fuel-water emulsions, associated gas, liquid biofuel, biogas and other fuels outside globally recognized standard fuel specifications, should be carefully analysed for each power plant project prior to use. Due to the nature of these types of fuels their quality might vary over time and consequently fuel quality analysis should be done on a regular basis.

The engine generating sets used in Wärtsilä power plants are driven by heavy-duty medium-speed four-stroke combustion engines. These generating sets consist of an engine connected directly to a generator via a flexible coupling. The generator and engine are rigidly mounted on a common baseframe.
