Figure 1: The Värnamo Demonstration Plant. V AERNAMO W ASTE Objectives The objective of this demonstration project is to re-commission the Värnamo Gasification Plant and demonstrate its operational capability with 100% RDF and up to at least 25% used tyres (TDF). These waste recovered fuels are attractive due to their low cost and are produced throughout the EU and other developed economies. The technology involved (pressurised gasification) is innovative and this is the only IGCC plant operated by biomass fuels worldwide. The proposed technology is targeting the medium range of power applications (10-20MWe) for which there is no reliable waste gasification technology available in the market. The plant will generate 6MWe and 9MWth for district heating. The implementation of this project not only provides an accelerated penetration of IGCC technology but will also address energy production from low-cost waste fuels found in abundance all over the EU. Re-operation of the Värnamo gasification plant (RDF - TDF use) Challenges The main targets of the project are: • to evaluate the performance, environmental data, fuel flexibility, system designs, and the operation and performance of individual components of the IGCC plant for 100% RDF and 25% TDF • to implement the appropriate modifications to plant systems and components, so as to conform to the functional and environmental requirements made, with satisfactory availability and operating economy for this and future plants • to evaluate the operating and maintenance costs of the plant, so that future plants can be economically built • on the basis of the results of the test programme, to analyse the technical and economic opportunities available for the technology. Project structure The overall objective of the project is to “perform a long operational test of untested, waste fuels in the Värnamo IGCC plant and derive reliable assessment of technical, environmental and economic performance of an entire fuel-toelectricity waste thermal conversion technology”. In order to meet this objective a consortium, led by a private company (Helector S.A.) and also incorporating a research institute (CRES/partner) and a utility company (Sydkraft AB), has been assembled. It has worked out the details of properly re-operating and modifying the Värnamo plant so as to carry out extended tests on RDF and TDF fuels. 64 In order to carry out the project, seven work packages (WPs) have been scheduled: WP1: Project coordination WP2: Adjustments for the reduction of plant operating costs WP3: Product gas conditioning prior to electricity generation WP4: Test campaign for Refuse Derived Fuel (RDF) WP5: Test programme for Tyre Derived Fuel (TDF) WP6: Plant emissions monitoring and environmental performance WP7: Technoeconomics, market studies and dissemination activities Expected impact Cleaner energy systems, including renewable energies: • large scale generation of electricity from biomass and waste • more efficient biomass conversion systems • integration of renewable energy sources into energy systems. Economic and efficient energy for a competitive Europe: • improving the efficiency of new and renewable energy sources. In addition to the above, this proposal will contribute significantly to the following thematic priorities: • more energy efficient gas turbines, and, • optimisation of CHP systems.
Finally, the project will contribute to the overall aims and objectives of the Commission’s White Paper on Renewables, the Campaign for Take-Off and to the new directive for RES-based electricity generation. Progress to date The Värnamo Demonstration Plant was built during the period between 1991 and 1993, and was subsequently used in a comprehensive development and demonstration programme in which the technology, environmental impact, fuel flexibility and economics were evaluated. The Värnamo plant, see Figure 1, is now the world’s only existing complete and proven IGCC plant on biomass and waste fuels. Pressurised thermal gasification of solid fuelsand the subsequent combustion of the gas thus produced in a gas turbine, followed by a steam turbine cycle, is a technology that offers high electrical efficiencies. Using today’s gas turbine technology, net efficiencies in the order of 40 - 50% are perfectly feasible. Operation of the Värnamo plant has demonstrated that the technology performs very well. The fuel flexibility is wide and the emissions are low comparedto the present conventional biofuel-fired electricity generation systems.
