PLANT TECHNOLOGY The structure of the proposed plant is based on the so-called low-temperature organic Rankine cycle (LT-ORC), and may be summed up by the diagram in Figure 1 1. A heat source [1] generates heat, which is conveyed through a vector fluid circulating into a closed loop to one or more primary heat exchangers, usually a preheater and an evaporator [2], where said heat is transferred from the vector fluid to the working fluid fluid. The working fluid - a low-boiling, biodegradable, non toxic liquid when at room temperature - boils in the evaporator at a temperature far lower than...

INNOVATION Independently designed and manufactured using the most advanced technologies in finite elements and fluid-dynamics analysis (CFD/CFX), the ZE turbogenerators are designed from scratch to operate in a low-temperature organic Rankine cycle which uses a special working fluid that offers better performances and several advances over traditional steam turbines: • Low operational temperature which allow our systems to tap even low-grade heat sources; • High condensation temperature which may allow the use of simple air-cooled condensers; • Totally dry working fluid which means no...
