The DO49R is a single-shaft gas turbine featuring a built-in coaxial reduction gear, applied to drive the electric generators within low capacity power plants (from 2.5 to 15 MW and above).

Design features:

• built-in coaxial reduction gear (reduction ratio 1:4.66)
• 10-stage axial-centrifugal compressor
• tubular combustor (2 flame tubes)
• 3-stage turbine

Advantages:

• single-shaft design provides a high quality of output energy and good behavior at the unsteady conditions
• high fuel efficiency, that allows to reduce the cost of energy produced
• modular replacement of the gas turbine, reduction gear, other components in operation
• high sulfur corrosion and maritime climate resistance
• possibility to use the different fuels: gaseous fuels (natural gas, oil gas) and liquid fuels (kerosene, diesel fuel)

Application:

The DO49R gas turbine is the base for the GTES-2.5/5.0/etc. power plants rated at low output capacity (from 2.5 to 15 MW and above), designed for heat and electric power generation in simple and cogeneration cycles.
