Increasingly, city councils of all Spain bet by the recovery of the forestrys of his demarcations and the one of Sant Llorenç Savall, situated in the region of the Western Vallès (Barcelona), is one of them. Between the aims of said recovery stands out the economic profit, thanks to the creation of new places of work, the saving in purchase of external fuels and of the possible development of a new line of business with the sale of the excedente generated; without forgetting the environingingmental profit regarding the cleaning of the forestrys and to the prevention of the forestry fires.

The City council of Sant Llorenç Savall initiated in 2009 the 'Pla Estratègic d'aprofitament of biomassa forestry per to uses energètics to the municipi of Sant Llorenç Savall' (Strategic Plan of aprovechamiento of forestry biomass for energetic uses in the municipality), elaborated by ECHO9 - Serveis i solucions mediambientals, a study on the feasibility in the recovery of the forestrys of the zone, that includes part of the territories of neighbouring municipalities, to end to look for the maximum profitability of the project. The area of study occupies some 12.000 has and of these 43% are perfectly accessible for the aprovechamiento of the biomass, without need of extra costs to build roads of access. Of this study reflects that the fourth part of these zones of easy access belong to Sant Llorenç Savall with what the municipality has of some possibilities of car procurement, having the capacity to produce some 1.200 tonnes of annual biomass.

The restlessness by the conservation of the environingingment was one of the reasons by which the municipality of Sant Llorenç Savall posed the possibility to use forestry biomass for thermal sensors energetic use, but also the geographic situation of the territory and the vicinity of the source of supply of prime matter. This without forgetting the contribution to reduce the risk of forestry fires and the important impact that a project like this can have to socioeconomic level, boosting the use of alternative energies of future, creating put of local work, etc.

The installations of the municipal pavilion and of the Marquet of L'Was received a subsidy of 50% of the total of the investment of the ICAEN (Institut Català of l'Energia).

The study

In the study realizar evaluated six municipal installations like the most adapted to receive to a system of heating by biomass, already went by the antiquity of his installations, by the high consumption, for having of ideal equipments or of the suitable space for the silo of the biomass, or for treating of a building of new construction. These buildings are the CEIP Josep Gras, the project of new construction of a kindergarten, the current building of the city council, the building in remodeling of the Marquet of l'Was (future location of the city council), the centre for the third age and the house of culture.

Of these installations, those that were working did it with diesel like source of thermal sensors power. It is thus that, in the moment to analyse the economic saving, is the diesel the fuel used like reference. The price of the diesel was then (in 2009, during the manufacturing of the study) of 73,73 /MWh, whereas the price of the pellet was of 47,92 /MWh and the biomass of the zone of study of 28,19 /MWh.

Finally, selected two of the buildings to realizar the installations of biomass: the kindergarten The Patinet, that is of new construction, and the building of the Marquet of l'Was¸ that they were those that offered greater eases of space and access to the same for the location of the room of boilers and the silo.

Since it set up the first boiler KWB in the pavilion of sports in November of 2009 and, later, the second in the kindergarten in February of 2011, the city council has saved roughly €7.000 and has avoided the broadcast of some 43.900 kg of CO².

The Austrian manufacturer KWB

In the moment to choose a boiler of biomass for the first installation realizar in the Polideportivo Municipal, the City council of Sant Llorenç Savall opted by the Austrian manufacturer KWB, distributed in Spain by the Madrilenian company HC Engineering, known like a referent in Spain in the sector of the biomass. The good performance offered by the boiler of biomass of KWB and the high degree of satisfaction experienced by the City council motivated that this decided to follow betting by KWB for the two new installations. In these moments, three municipal buildings have a boiler of biomass of the Austrian manufacturer.

The Polideportivo Municipal of Sant Llorenç Savall has of a boiler of biomass KWB model Easyfire USP GL 30 of 30 kW with pneumatics feeding to silo of canvas of 5 tonnes, situated to 20 metres. It has a control for two circuits of heating. The installation was realizar by Energrup, the set up was to charge of HC Engineering on 27 November 2009 and the fuel used by this boiler is pellet.

For the building of new construction of the kindergarten The Patinet opted by a boiler of biomass KWB model Multifire USV GS of 50 kW that works with a system of feeding by aspiration, from silo of canvas of 5 tonnes, that is situated in the interior of the silo of work of the installation. This silo built to be used in the moment to have of the forestry biomass of the zone.

In the installation of the Marquet of L'Was has installed a boiler of biomass KWB model Multifire USV ZI 60 of 60 kW with feeding from silo of work. Said silo has capacity, depending of the fuel used, for 16 tonnes of pellet and some 6,5 of astillas.

The kindergarten The Patinet has the qualification 'To' of the register of certificates of energetic efficiency of buildings of Catalonia that awards the ICAEN and with the sign GreenBuilding, that awards the European Commission and that complements the Directive 2002/91/CE of the European Parliament and of the Council of 16 December 2002 relative to the energetic efficiency, with the aim to boost the energetic saving of voluntary form. It fits to add that the City council of Sant Llorenç Savall was the first city council of Catalonia and the first of Spain in receiving the sign GreenBuilding for a public building.
