Turboden is a leader in biomass power generation with over 220 ORCs operating on biomass around the world, including one plant in Australia. Biomass can come in many forms such as:

  • Wood Biomass, such as sawdust, chips, bark and treated wood;
  • Other Biomass, such as straw, rice husks and bio-sludge;
  • High organic content waste.

There are challenges to designing systems capable of utilising each type of fuel to make electricity. Though a heat plant needs to be customised to the resource, an ORC can be selected from one of our many ‘standardised’ modular units.

Advantages of Organic Rankine Cycle

Compared to competing technologies, the main advantages obtained with ORC technology are:

  • High cycle efficiency (especially if used in cogeneration plants);
  • Very high turbine efficiency (up to 90%);
  • Low mechanical stress of the turbine, due to low peripheral speed
  • Low RPM of the turbine allowing the direct drive of the electric generator without reduction gear;
  • No erosion of the turbine blades, due to the absence of the moisture in the vapour nozzles;
  • Very long operational life of the machine due to the characteristics of the working fluid, that unlike steam is non eroding and non corroding for valve seats tubing and turbine blades;
  • No water treatment system is necessary.

There are also other advantages, such as simple start-stop procedures, quiet operation, minimum maintenance requirements and good partial load performance.
