From an idea of EXERGY CEO Claudio Spadacini, after years of research

and development EXERGY launch the

Radial Outflow Turbine into the marketplace.

At theforefront ofinnovation

EXERGY become part of the Maccaferri Industrial

Group. Backed by the strong economical and organizational support

of the Maccaferri Group EXERGY start a period of rapid expansion and success in the market.

In September Exergy start up in Verbania the

first high enthalpy 1 MW Radial Outflow Turbine.

EXERGY install the world’s first Radial

Outflow Turbine in a geothermal binary plant

in Tuscany. The project is developed for the

Bagnore III power plant in Mount Amiata (Italy)

for Enel Green Power and represents a giant leap

forward for green energy allowing utilisation of

the untapped potential of an existing geothermal

resource.

Pamukören 1 and Pamukören 2, EXERGY’s

first geothermal projects in Turkey, in Menderes

Basin area, become operational. This project

was commissioned by Çelikler Jeotermal and EXERGY participated in

a Consortium with other partner companies.

In June EXERGY move to a custom-built

facility near Malpensa gathering all engineering,

manufacturing and operational functions to allow the R&D and engineering team to

work side by side with the manufacturing

department.

EXERGY experience consistent growth and success in the Turkish

market, winning key contracts and becoming established as a market leader for binary power

plant equipment.

In July EXERGY open a Turkish subsidiary

company based in the city of Izmir in order to

start local manufacturing of the EXERGY Radial Outflow Turbine and

directly serve the Turkish market.

In June the Denizli Tosunlar geothermal

power plant, the world’s first equipped with a

2-pressure-level cycle on a radial outflow

single-disk turbine, becomes operational.

This plant, commissioned by the client Akça Enerji,

represents a unique technological milestone for EXERGY confirming

the company at the forefront of innovation.

Organic Rankine Cycle technology is employed efficiently for power production from low to medium temperature heat sources in the range of 80 to 400 °C.

The working principle of an ORC is similar to the most widely used steam Rankine

cycle. The main difference is the use of organic substances as working fluid, such as hydrocarbons and refrigerants, instead of water or steam. The organic working fluid has a lower boiling point and a higher vapour pressure than water and is thus able to use low temperature heat sources to produce electricity in a more

efficient way.The fluid is chosen to best fit the heat source according to their differing thermodynamic properties, thus obtaining higher efficiencies. Moreover ORC can also be an ideal solution when the size of the application is too small for a steam power plant to be feasible.

1 The heat exchanger recovers heat from the primary source transferring it to a heat transfer fluid (hTF) 2 The organic fluid warms up in the preheater and vaporizes in the evaporator, extracting heat from the hTF, which returns to the heat exchanger 3 The vapour expands in the turbine, which produces electricity through the generator 4 Recuperator recovers the high-temperature heat still available in the vapor at turbine outlet transferring it to the organic liquid before the preheater 5 The condenser extracts the low temperature heat and turns the vapor back into liquid state 6 The pump increases the fluid pressure sending it to the recuperator, thus closing the cycle.

The pertinent technologies are covered by multiple IP rights and EXERGY continues to work on further advances and new applications of its technology.

The key feature of the Radial Outflow Turbine configuration is the capability to convert the energy contained in the organic fluid into mechanical power with higher efficiency than the competing technologies on the market such as the axial or radial inflow turbine.

Enel Green power was looking to exploit the untapped potential of an existing geothermal source in Tuscany. Enel Green power needed a compact binary plant integrated with a 20 MW single flash plant already in place.

EXERGY’s solution was a fully integrated cycle system that, thanks to its technological innovation, offers the possibility to use a geothermal source until now unsuitable due to low temperature of the primary fluid (100°C - 180°C).

EXERGY has provided superior energy efficiency compared to traditional solutions and the plant now produces electricity to approximately 2,500 households thus preventing the consumption of 1,600 tons of oil equivalent per year.

Energy efficiency today has become a must for smart companies looking to reduce their environmental impact and increase their profitability.

Heat recovery has become one of the major choices towards achieving these aims for the industrial sector and orc technology is considered one of the most effective solutions for lower temperature applications (from 90°c up to 350 °c) and for small power output.

EXErGY has brought all the advantages of orc systems to a higher level thanks to the innovative radial outflow turbine (rot), that allows better efficiency and lower operational and maintenance costs, also eliminating the requirement for water treatment and make up.

Energia Vulture alto Bradano S.r.l had two main needs, to dispose of waste from grape and olive production and waste from the local wood processing industry, using environmentally suitable methods.the second need was to increase their profitability by giving electricity back to the grid.

EXErgy provided a packaged orc unit that combined with a thermal oil boiler, efficiently converts the agricultural waste into electricity.

the biomass plant is fully operating and is producing 990 kWe with a 24% efficiency of the radial outflow turbine.
