This document provides a detailed description of the ORC Module ZE-100-ULH, focusing on its plant technology, innovation, and process data. The module operates on a low-temperature organic Rankine cycle (LT-ORC) to convert heat into electrical energy efficiently.
The ORC system utilizes a heat source to generate heat, which is transferred via a vector fluid to primary heat exchangers, including a preheater and an evaporator. The working fluid, a low-boiling, biodegradable liquid, is vaporized and drives a turbine to produce electricity. The system is designed to inject power into the grid or for self-consumption. Excess heat can be used for other applications or dissipated using cooling systems.
The ZE turbogenerators are designed for low-temperature operations, allowing the use of low-grade heat sources. Key features include high reliability, reduced maintenance costs, and environmental friendliness. The system operates with no atmospheric emissions and uses recyclable materials. It is suitable for small plants (<1MWe) and includes advanced monitoring and diagnostic systems.

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...
