UPSWING Objectives The UPSWING process combines both well-known energy conversion principles, mainly of waste incineration, plus coal-fired power plant combustion for heat/electricity generation. The project will be applicable on a competitive level with present technology to current and future EU members. UPSWING ensures the sustainable supply of heat/electricity more economically with improved efficiency. This will be proven by theoretical and experimental investigations. Environmental and social aspects, such as alleviating waste-disposal problems and improved control of pollutants, are taken care of in the project by testing lab to large scale. The objectives of this project are to evaluate the UPSWING process and assess its potential by experimental and theoretical investigations. The results of UPSWING will be compiled in a guidebook which will be prepared by all partners. Unification of power plant and solid waste incineration in the grate The UPSWING project, funded by the European Commission under the Fifth Framework Programme, started on 1 January 2003 and will extend over 36 months. Eleven organisations from seven countries, including four NAS countries (Newly Associated States), are participating in this European project. The project is being coordinated by the Institute of Process Engineering and Power Plant Technology (IVD) of the University Stuttgart (Germany). Process description The UPSWING process (see Figure 1), which has been developed by the Forschungszentrum Karlsruhe (Germany), proposes to use the economic advantages of coupling a waste incinerator with a power plant while avoiding the unwanted effects of waste sorting as well as the risk of additional emissions and the deterioration of power plant residue quality. The process uses the partly cleaned flue gas of a waste incineration plant as part of the combustion air in the power plant [a]. Another option is to use it as carrier gas in the coal mills [b]. It also combines the steam circuit of both facilities [c]. Using this combination, the waste combustion part does not require the energy recovery unit and major parts of the gas cleaning system. 140 The waste combustion flue gas is de-dusted and partially cleaned during a simple acid wet scrubbing stage. This procedure guarantees the almost total removal of particle-bound heavy metals, of more than 95% of HCl, and of approximately 90% of Hg. The partially cleaned gas still contains SO2 and NOx as well as the gaseous PCDD/F. The PCDD/F will be totally destroyed inside the combustion chamber. NOx is converted in the re-burn zone and SO2 is removed in the respective abatement system of the power plant. The process keeps the waste combustion specific pollutants away from the power plant, as compared to a direct co-combustion concept. The main advantages of the UPSWING process can be summarised as follows: - Significant cost reduction compared to a samesize standalone waste incinerator; - Higher electrical efficiency of the waste incinerator by coupled steam circuits; - CO2 reduction by substitution of coal in the power plant; - Efficient low-cost flue gas treatment in the waste incinerator; - Potential of technology transfer to other (nonparticipating) European countries; and - Alleviation of problems with waste production and disposal.
Figure 1: The UPSWING process. Project structure The novelty of the concept and its uniqueness when compared to other state-of-the-art waste incineration processes has to be emphasised. The project has set out to assess and evaluate the potential of the concept as well as of single process steps. To answer questions that arise when considering its implementation, six work packages have been defined (see Figure 2). The work packages are consequently interrelated, thereby securing an intensive exchange between the partners. Expected results and current state of work The results of the UPSWING project will be compiled in a guidebook. This guidebook will include the following topics and will enable the short-term application of the UPSWING process: - Evaluation of waste quantities and qualities of the current waste management system; - Evaluation of power plant locations, including non-technical basics; - Evaluation of the most suited power plants available for coupling in the NAS; - Start-up/shutdown/emergency measures; - Influence of coupling on the power plant process; - Construction and adaptation of highly flexible flue gas cleaning systems; - Adsorption capacities PCCD/F on pulverised coal and their destruction in the furnace; and - Technical solutions for lowest NOx/Cl/Hg emissions in the complete process. Figure 2: Project structure. Current work focuses on the evaluation of available waste qualities/quantities and suitable power plant locations in the participating NAS countries. Basic calculations are being made along with the modification/construction of the necessary equipment in preparation for the upcoming experimental investigations. Expected impact and exploitation Dissemination of results for application in the EU and/or NAS is most probable as the project team consists of industry, research organisations and universities from EU countries and NAS. Two industrial NAS partners are interested in the novel process, and specific sites have been designated for detailed investigation. To enable the public to access the results, a project website has been established. 141 INFORMATION References: ENK5-CT-2002-00697 Programme: FP5 - Energy, Environment and Sustainable Development Title: Unification of Power Plant and Solid Waste Incineration – UPSWING Duration: 36 months Contact point: Jörg Maier Universität Stuttgart Tel: +49-711-11212177 Fax: +49-711-1212291 j.maier@ivd.uni-stuttgart.de Partners: Universität Stuttgart (D) FZ Karlsruhe (D) Technical University Sofia (BG) Power Plant ‘Turow’ – Bogatynia (PL) Mitsui Babcock Energy (UK) Kema Nederland (NL) Polytechnical University of Timisoara (RO) Wroclaw University of Technology (PL) Czech Technical University of Prague (CZ) Sokolovska Uhelna (CZ) Institute of Power Studies and Design (RO) Website: http://www.eu-projects.de/upswing EC Scientific Officer: Erich Nägele Tel: +32-2-2965061 Fax: +32-2-2993694 erich.naegele@cec.eu.int Status: Ongoing
