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 that...

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 turbine...

ZE-30-ULH DIMENSIONI SKID The ORC module is supplied mounted on a self-supporting frame (“skid”) hosting all module components, ready to be connected to heat source and heatsink. Where necessary, this skid is capable of fitting inside a standard 20” container for shipping. Skid weight and dimensions are listed on the left and below. Please keep in mind that the skid ideally requires at least 1.5 meters of free space on all sides for easy maintenance access. Zuccato Energia, as system developer and manufacturer, may also upon request design and build the module with custom dimensions and working...
