Biagi Romeo Pig Farm
Manager: Società Agricola Biagi Romeo S.s
Location: Borgoforte (Mantua, Italy)
Plant: 1 x ZE-50-ULH LT-ORC module in outdoor container
Application: Waste heat recovery from flue gases and cooling jackets of a biogas-fueled Jenbacher engine
The Biagi Romeo farm, located in Borgoforte, near Mantua, Lombardy, Italy is a livestock farm specializing in pigs, which has decided to acquire a biogas production system fueled by the fermentatio of the sewage created by its 10,000-odd pigs.
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 system Texas Green Technologies supplied through its Italian partner, Zuccato Energia, is a ZE-50-ULH low temperature organic Rankine-cycle module which recovers waste heat from the 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.
