ORC technology


High heat generation follows various industrial processes. In the most part of cases it is utilized in different coolers or simply vented.

At the same time prices of organic fuels and electricity go up and up, that becomes a motivation for industrial enterprises to seek for alternative ways of producing energy, utilizing secondary energy sources. We offer ORC-plants (generate electricity, use organic fluid as heat-transfer agent) for producing electrical and secondary heat energy.

Depending on technological process, secondary energy resources can be found in various environments:

  • Stack effluents (after gas turbines, combustion engines, various furnaces and burners)
  • Air
  • Hot water
  • Steam

Temperature of secondary energy resources (SER) can have a range from 300-400 °С to 80-90 °С. Characteristics of SER are important as well as their temperature and flow rate. The amount depends on technological process.

how it works?

ORC scheme

ORC technology is relatively young. It was developed and spread in 70s-80s. Rankine cycle was invented in the end of the 19th century, however only in the 20th it made a big evolution step moving to use of organic fluid with high molecular mass as operating fluid. Principle of cycle operation is ultimately simple: heat source heats a loop with thermal oil that transfers heat to working fluid. Organic fluid gets though ORC loop and evaporates making a turbine to rotate. The turbine is connected to electric generator. After getting through turbine organic fluid is cooled and condensed. The next step is its returning back to the beginning of cycle in liquid state.

Organic Rankine cycle has various applications, which normally depend on heat source. It can be exhaust heat on industrial enterprises, biomass, geothermal heat etc. The principle is always the same that heat excess turns into electricity and residual heat. For us the most interesting are domains biomass and industrial applications.

Organic Rankine cycle has efficiency distribution circa

14-15% electricity + 75% residual heat + 8% stack gases loss + 2-3% cycle loss.


  • High electrical efficiency rate
  • High internal relative efficiency of turbine (up to 85%)
  • Low turbine mechanical tension thank to low peripheral speed
  • Lack of reduction gearbox between turbine and generator
  • No blade erosion due to lack of moisture in steam nozzles
  • Simple start and stop of plant
  • Constant automotive control
  • No need of physical presence of manipulator
  • No noise
  • Wide adjustment range (10-100%)
  • High efficiency in variable-load operation mode
  • 3-5 hours pro week for maintenance
  • Long life

we offer

We collaborate with companies of Western Europe and the Republic of Belarus that have great experience in creation of energy complexes implementing ORC-plants. We offer full package of services within such energy complex building projects.

You can find ORC-solutions within following ranges:

  • Low power (10-30 kW)
  • Medium power (270 kW)
  • High power (600-2200 kW)

We can also arrange manufacturing of non-standard plant with power up to 10 MW.

In 2015, we successfully completed our first ORC-project.  The plant was integrated within reconstruction of biomass (wood chips) boiler-room. Our team worked in close collaboration with Turboden s..r.l. (Italy, producer) and Belarusian state technical university as technical consultant. Supplied module is Turboden 14 CHP (1,4 MW electric energy).
