Plant:

1 x ZE-50-LT Low-Temperature Organic Rankine Cycle (ORC) Module, nominal output 50 kWe

Nominal output:

50 kWe

Application:

Heat recovery from engines
(Jenbacher biogas-fueled genset)

Location:

Province of Venice, Veneto, Italy

Manager:

Private Italian firm

The client who commissioned this plant is a livestock farm specializing in cattle and located in the province of Venice, Italy, which has decided to acquire a biogas production system fueled by the fermentation of the sewage created by its cows.

The biogas produced in the fermenting tanks is used as fuel for a micro power plant based on a 637-kW engine by the german firm Jenbacher. Said plant takes advantage of the favorable all-comprehensive tariff the Italian government grants to new small power plants powered by renewable energy sources

The ORC system supplied – a ZE-50-ULH low temperature organic Rankine-cycle module – recovers waste heat from flue gases and cooling jackets of the forementioned Jenbacher engine, thus contributing significantly to the overall system efficiency and productivity.

The LT-ORC module is entirely contained in a custom container, located outdoors, which is both compact (4,2 x 1,5 x h 3,1m) and totally weatherproof. This container hosts the whole ORC system, including turbine, secondary heat excangers and control panel, as well as a climatization system for the control panels. Cooling for the condensation part of the cycle is ensured by an EvapCo cooling tower located beside the container

 

The fuel used by the Jenbacher engine (biogas) is an environment-friendly, renewable energy source made competitive by state and regional incentives. It is also CO2-neutral, as burning biogas releases in the atmosphere the same quantity of CO2 which was once captured by the plants that went to feed the animals.
