The Tànger power plant is being built in the centre of 22@, in the heart of the technology district's media cluster, on the corner of Tànger Street and Roc Boronat Street. This second plant - initially conceived as a peaking plant - is intended to guarantee supply during periods of high demand, and to come into service if the need arises or for possible contingencies.
The Tànger power plant was opened in April 2012 and is a clear example of the significant growth of the urban heating and cooling network in the Besós and 22@ areas.
Top Floor (214m2) for the arrangement of the natural gas installations (ERM) and cooling towers.
Mezzanine (281 m2) for administrative and control use of the plant.
Ground Floor (564 m2) where the transformers and electrical installations, the natural gas boilers and a show room are located.
Basement floor (2.090 m2) which houses the 3 ice storage tanks, refrigeration production equipment and water treatment.
The Tánger power plant conducts the combustion gases from the boilers through a subway duct that expels them through the 36 m brick chimney of the old Ca l'Aranyó textile factory, which was built in 1872 by Claudi Arañó i Arañó in the style of the textile mills of Manchester.
All the equipment selected is of the industrial type and is required to have high-energy efficiency, low emissions and reliability.
Cold production:
2 Friotherm compressor units of 6.7 MW for the production of glycol water (negative cold -7ºC / positive cold 4ºC).
1 Quantum compressor unit (10 magnetic levitation compressors) of 6.7 MW for the production of cold water (positive cold 4ºC).
Heat production:
2 natural gas boilers of 13.4 MW for the production of hot water.
Technological innovation and environmental commitment, the two cornerstones of Districlima's operation, are embodied through an advanced ice storage system, which allows the production of cooling energy during periods of low demand and then distributes it during periods of high demand.
This solution, in addition to allowing rational and efficient energy management, involves having a real cold storage "tank" that improves the safety of the entire system.
The plant has large ice tanks of 40,000 kWh each, through which glycol circulates at an average temperature of -4ºC.
Each tank contains 45 galvanized steel batteries through which glycol water circulates to produce ice in the contour of/inside the small tubes that make up the battery. The dimensions of each of the 45 batteries (5.5 x 1.6 x 1.7 m) give an idea of the size of this installation.
