- RADIAL OUTFLOW TURBINE
Exergy’s Radial Outflow Turbine
Conceptualized by Exergy the Radial Outflow Turbine (ROT) was launched in 2009, innovating the global ORC industry. It is a confirmation of Exergy’s status as a market game changer.
MORE EFFICIENCY AND FLEXIBILITY WITH THE ROT
What is the key feature of the ROT?
The ROT configuration makes it possible to convert the energy contained in the organic fluid into mechanical power with higher efficiency than competing technologies on the market such as the traditional axial or radial inflow turbine.
Our Radial Outflow Turbine technology is covered by multiple IP rights and Exergy’s R&D team is always working to develop it further with new patents.
ROT strengths:
1
NATURAL ACCOMODATION OF WORKING FLUID EXPANSION
As it expands, the fluid encounters greater surface area, causing taller blades in the first and shorter blades in the last stages, thus facilitating a broader range of applicable fluid conditions
2
LOW SPEED TURBINE
No gearbox
High reliability
Low noise
Longer life of the bearings
3
STRAIGHT BLADES AND RADIAL DESIGN
Minimal 3D effects and turbulence
4
EASE OF MECHANICAL GROUP EXTRACTION
No fluid loss or drainage
Easy and rapid maintenance
Less tip leakage and disk friction losses
No “overhaul” maintenance on the turbine
5
SIMPLE DESIGN
Compact solution
Simple and easy construction
6
STANDARD MECHANICAL DESIGN FOR EACH TURBINE FRAME
The fluid-dynamic design of each turbine is optimized in order to reduce supply time, guaranteeing maximum efficiency without the need for mechanical redesign
7
MULTIPLE PRESSURE ADMISSIONS POSSIBLE ON A SINGLE DISK
Cost effective solution
Less limitations on cycle pressure
20% more power than a single level system with a simple configuration
Suitable for temperature heat sources as low as 90°C
8
UP TO 9 STAGES ON A SINGLE-DISK TURBINE
Better exploitation of high enthalpy resources
Extreme flexibility for changing heat source conditions, in terms of flow, temperatures and constituents
Up to 6% additional efficiency over the axial turbine
