The Wärtsilä 34SG-LPG is a four-stroke, spark-ignited, lean-burn gas engine generating set. It has been specifically designed to operate on propane gas fuel and provides an excellent fit for flexible baseload and industrial applications.
Wärtsilä 34SG-LPG is based on proven Wärtsilä 34SG technology designed for natural gas operation, with more than 1300 units having been delivered during the past 20 years. The Wärtsilä 34SG-LPG features a wide power output range from 4.2 to 7.4 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.

| * Rated electrical power and electrical efficiencies are given at generator terminals at 100kPa ambient pressure, 25°C suction air temperature and 30% relative humidity, and without engine driven pumps. Power factor 1.0 (site). Electrical efficiency with 5% tolerance. Site conditions, fuel and applicable emission limits may have an impact on performance figures. Please contact Wärtsilä for project-specific performance data. Emission figures for LBF must be evaluated case by case. Catalyst systems are designed based on project specific requirements. Certain fuel components are poisonous for catalyst elements. Maximum amount of these components to be limited in the fuel in applications where catalyst system is installed. |
