Biomass Power Plant Baena, Spain

The task EL Oleicola El Tejar in Baena, Andalucia, is one of the largest olive oil producers in Spain. Until now, olive waste generated during the production process was disposed of on large waste disposal sites. However, since Spanish legislation encourages the utilization of regenerative energies, using olive waste for generating electricity in a biomass power plant was found to be advantageous. The solution Standardkessel has developed the first European biomass power plant capable of using “alperujo”-olive waste generated during the extraction of olive oil in a centrifugation process – as fuel. In December 1998, the contract for development and turn-key construction was concluded between Agroenergetica de Baena S.L. and Standardkessel. The start-up, successful performance test run and approval took place in February, 2002 – faultlessy and in compliance with all contractually agreed-upon guarantees. Spanish and European legal requirements were not only fulfilled, but in terms of emissions, even surpassed in many cases. The maximum electrical output is 25 MW.

Power Plant for the Combustion of used Tires, Polgar, Hungary

The task In Hungary, the company TechCon disposes of used tyres and production residues from the production of tyres. The accumulating substances to be disposed of, such as passenger car tyres, truck tyres and the tyres of heavy agricultural machines are to be disposed of by thermal means and the inherent energy is to be converted into electricity. The residual substances accumulating as a result of incineration as well as flue-gas cleaning are either to be treated to obtain valuable substances or to be sent to landfills. The solution TechCon placed an order with Hungarian company Csöszer as the general contractor for the supply of a power plant on a turnkey basis. The order for the thermal part, consisting essentially of the fuel conveying system, the steam generator with grate stoker and flue-gas cleaning was secured by Standardkessel. The tyre handling equipment separates and transports the whole tyres from the storage area to the feed device for the firing system. The heart of the plant is made up of the underfeed stoker and the vertically arranged natural circulation boiler which generates the superheated steam for feeding into the connected steam turbine. The flue gases produced are freed of all pollutants in a flue-gas cleaning plant based on the dry sorption process and are discharged into the atmosphere via a stack after cleaning

RDF-HEAT-and-Power Plant Stavenhagen, Germany

The task In order to supply the production facilities of a large food supplier economically with energy, a combustion line together with all auxiliary equipment was to be designed in consideration of the prevailing geographic conditions. Meeting the requirements for high availability, the plant concept was developed on the basis of comparable realised plants. Besides the steam generator and combustion system the order placed by Nehlsen AG, acting as waste-management Company, investor and plant operator, comprised further plant components and services. The solution On the basis of comparable realised RDF-plants, Baumgarte Boiler Systems GmbH developed a concept which conforms to the prevailing conditions and meets the requirements for a high availability period. After a long planning phase as from February 2004 Nehlsen AG and Baumgarte Boiler Systems GmbH finally signed the contract in February 2005. The very challenging time schedule was kept so that the commissioning, the performance record and plant takeover took place in consideration of the agreed conditions in the second quarter of the year 2007. Scope of supply Complete combustion line from fuel-feed hopper up to stack outlet: Combustion Grate System (water-cooled), SNCR Ignition and Auxiliary Burners Fuel Oil Storage Tank and Fuel Oil Supply Slag-Removal Systems Main-Steam Generator incl.
