Industrial Thermal Biomass System in the wine cellars of
Bodegas Emina S.L.
Valbuena de Duero (Valladolid)
PROJECT TEAM
Bodegas Emina, S.A.
FUNDING
Partially funded by a subsidy of 51.000 Euros granted through the Programme for Savings, Substitution, Cogeneration and Renewable Energies from the Castilla - León Regional Council.
DESCRIPTION OF THE PROJECT
Bodegas Emina installed a biomass boiler in 2005 to
heat the company's centre for wine and grape development.
Bodegas Emina is a wine industry in Ribera del Duero integrated in
the Matarromera group, with 100 permanent employees and 100
temporary staff.
The premises include a building with an area of 10,000 m2 (where
the wine cellar is situated) as well as the training and congress
hall, laboratories, offices, museum, shop and distillery among
other installations.
In terms of energy the following could be noted:
Biomass supply: The biomass fuel supply used has two origins: one originates from vine shoots, grape and vine waste products (mainly stalks), and the second from other sources, pine cones and kernels from other activities in the area.
Thermal station: The boiler capacity is 172,000kcal/h (200kW). Feeding is automatic and the combustion furnace is grated. The boiler also consists of a pyro-tubular system, smoke purifier cyclone and heat recovery system. The liquid that carries the heat is water at 90 ºC. Solar panels for the production of hot water for sanitary use have also been installed, together with a complimentary gas boiler.
Distribution and consumption of thermal energy: The thermal energy produced is used both in the industrial process and in the building's heating system. Its function is principally based on the reception of a current of hot water that is then sent to its final consumer destination.
CHALLENGES FACED
The company's technicians were faced with the
dilemma of either using their own fuel supply, which is cheaper and
easier to obtain, or higher quality biomass fuel bought from
suppliers. Regardless of this, the company has incorporated a
grinder for shoots, to produce a more reduced and homogenous end
product for their own use.
INNOVATIVE PRACTICE
The use of renewable energy, together with other developments not
directly related to energy, such as cosmetics, based on grapes or
wine, form the elements of innovative practice in Emina which makes
it stand out from other companies in the same sector.
LEGISLATION
There is no specific legislation for this kind of installation,
except the RITE (Technical Regulation for Thermal
Installations).
LESSONS LEARNT
The lessons learnt can be summarised as follows:
Energy: The use of biomass avoids having to depend on external energy sources. Energy diversification is estimated in 49 toe per year.
Technological: The incorporation of modern automated biomass systems is currently an innovative and distinctive element in the wine and grape sector.
Environmental: Contaminating emissions are minimised and the company's waste products are appropriately self-managed.
Economic: The cost of thermal energy is reduced.
