Waste Heat Recovery System

Our waste heat recovery technologies mitigate climate change by generating clean energy from complex industries that emit waste gas and heat

Invest Energy’s one of the kind Waste Heat Recovery (WHR) power plants is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually for an increased efficiency. It is highly suitable for distributed generation, that generate electric and thermal power exploiting multiple sources, such as renewables (biomass, geothermal energy, solar energy), traditional fuels and waste heat from industrial processes such as furnaces and klins, waste incinerators, engines or gas turbines. These industries include cement, glass, steel, manufacturing and power plants.

Our core technological focus is WHR Organic Rankine Cycle (ORC) systems whose guiding principle is based on a turbo generator working as a conventional steam turbine to transform thermal energy into mechanical energy and finally into electric energy through an electrical generator. Instead of generating steam from water, the ORC system vaporizes an organic fluid, characterized by a molecular mass higher than that of water, which leads to a slower rotation of the turbine, lower pressures and no erosion of the metal parts and blades.

The clear advantages of an ORC include:-

  • Zero use of fuel
  • Ensures higher efficiency of turbine
  • Simple stop and start up procedures
  • Good system efficiency at partial load
  • Very long lifetime, (around 25 years)
  • No water consumption
  • No need of manpower to run the system
  • Simple and low maintenance
  • Excellent operational performance: >98% availability

We also develop Steam Rankine Cycle plants depending on the clients’ requirements and industry needs as both systems have its respective benefits. A life cycle analysis and assessment process is undertaken for every project that we develop around South East Asia.
