About Biomass Heat Recovery
The traditional rankine cycle is a thermodynamic cycle widely used by power plants to convert water into steam, then expanding that steam through a turbine to produce mechanical work. The Organic Rankine cycle (ORC) is a refinement of this technology, using an organic working fluid in place of water. This working fluid, in our case Pentafluoropropane, has a boiling point less than that of water in order to utilize lower temperature heat sources when compared to larger rankine cycles.
​
Our partners, ElectraTherm uses an ORC with proprietary technologies to generate up to 125 kW (with a 250 kW unit in development) of clean electricity from heat sources as low as 70°C. These lower ranges open up opportunities across industries that previously lacked sufficient heat for power generation. Operators take advantage of their excess heat to generate sustainable power – increasing efficiency, reducing energy/fuel costs, and decreasing their carbon footprint.
ElectraTherms Technology
​
The centerpiece of ElectraTherm’s ORC systems is a specially-designed twin-screw expander from parent company, BITZER. The implementation of this technology represents a dramatic shift from previous ORC technologies utilizing radial or axial turbines – providing a more cost efficient, robust design that greatly enhances reliability.
​
Since our systems are using an expander with lower temperature heat, there is less pressure on the pump and lower operating speeds compared to turbine technologies – leading to easier operation and less maintenance. The expander also tolerates “wet” dual-phase flow, allowing it to reliably generate power while accepting variations in both temperature and flow while allowing for a turbine’s worst fear – moisture.
​
ElectraTherm’s ORC systems are flexible and scalable – which means easy integration and the ability to scale from 75 – 125 kilowatt (or less) to multi-megawatt applications.
