Advantages
- possibility of working on various types of fuel: gaseous (natural gas, associated petroleum gas) and liquid (kerosene, diesel fuel)
- the ability to switch from one type of fuel to another without stopping the engine
- high efficiency and fuel efficiency
- design specially developed for use in marine conditions, approved by the Russian Maritime Register of Shipping
- high reliability and service life of gas turbine engines and units based on them (gas generator tested in operation as part of gas turbine drives of gas compressor units)
Application
The E70/8RD engine is the basis of the gas turbine electric generator SGTG-8 with an electrical power of 8 MW for use in power plants of a wide range of ships, as well as thermal power plants of industrial and municipal facilities (including offshore and coastal).
