Organic Rankine Cycle

Since 1980

Turboden is an Italian firm and a global leader in the design, manufacture, and maintenance of Organic Rankine Cycle (ORC) systems.

ORC generate electric and thermal power exploiting multiple sources, such as renewables (biomass, geothermal energy, solar energy), traditional fuels, and waste heat from industrial processes, waste incinerators, engines or gas turbines, highly suitable for distributed generation.

Today Turboden expands its solutions with gas expanders and large heat pumps to contribute to the worldwide efforts to mitigate global warming by creating reliable and clean energy systems.

Turboden is part of the Mitsubishi Heavy Industry Group.

Designed for decarbonisation.

Large Heat Pumps (LHPs) are at the forefront of the strategy for the electrification of heat in an increasingly decarbonised power grid. Through the supply of LHPs, Turboden wishes to play a broader role in the decarbonisation of the district heating sector and of some energy-intensive industrial processes.

Turboden gas expander is a solution to enhance the energy efficiency of a natural gas network infrastructure, producing electricity by taking advantage of the reduction of gas pressure from the delivery level to the one required by users, be they residential or industrial.

Turboden Organic Rankine Cycle (ORC) units can produce electricity by recovering residual low-grade heat

from industrial processes and from reciprocating engines, gas turbines, and fuel cells operating on open cycle.

Power range: up to 20 MW electric per single shaft.

Thermodynamic features and consequences
  • Superheating needed
  • Risk of blade erosion due to possible liquid formation during the expansion
  • High enthalpy drop – turbine with high stages number
  • No need to superheat
  • No risk of blade erosion thanks to dry expansion in the turbine
  • Small enthalpy drop -turbine with low stage number
Operation and maintenance costs
  • Water treatment required
  • Highly skilled personnel needed
  • Periodic major overhaul
  • Water-free system
  • Minimum Operation & Maintenance cost
  • No major overhaul
  • Completely automatic
Other features
  • Low flexibility with significantly lower performances at partial load
  • Convenience for large plants and high temperatures
  • High flexibility – Wide operational range from 10% to 110%
  • High availability (average >98%)

NOTE: steam turbine suffers partial load operation due to high risk of blade erosion
