An Italian municipality of 12,030 inhabitants in the province of Arezzo, in Tuscany. It is located in the upper Valdarno, on the right bank of the Arno. The territory covers about 86 km² and includes the valley where the capital is located, as well as large hilly areas that are home to some of the many small towns. The hilly area is covered with gullies.
In 2011 CPL CONCORDIA was awarded the contract for the construction and management of a biomass district heating plant to serve the school and sports complex of the Municipality of Terranuova Bracciolini. The project was completed in September 2012, after only 10 months from the opening of the work site, and this allowed the municipality to also benefit from the disbursement of a regional contribution of € 400,000 in addition to CPL’s € 1,400,000, for a total investment of € 1,800,000.
The integrated system of Supervision, Automation and Monitoring (BMS) covers all technological systems for the production of energy and seeks to optimise operations based on actual demand. All the substations are also managed and supervised with a remote monitoring system.
In the plant there is a boiler powered by wood chips with a heating capacity of 1,400 kW and a second boiler fuelled by methane with a similar capacity. The entire district heating system was equipped with a thermoregulation system for the remote monitoring of efficiency parameters.
To reduce emissions into the air a “bag filter” was also installed to comply with the limits set by A.R.P.A.T. An annual energy supply of about 1,900,000 kWt/h is expected, which will be produced almost exclusively by the combustion of about 700 tonnes of wood chips.
The use of biomass is considered to produce zero carbon dioxide because during combustion the same amount of CO2 emitted by the plants is released during growth. The new biomass district heating system – an excellent solution to exploit the material coming from the woods of the nearby Amiata mountain – supplies heat to nearby buildings.
