Description: Das Projekt "Verbesserung von Kombikraftwerken mit integrierter Kohlevergasung ausgehend vom Stand der Technik (Puertollano)" wird vom Umweltbundesamt gefördert und von Universität-Gesamthochschule Essen, Fachbereich 12 Maschinenwesen, Lehrstuhl für Technik der Energieversorgung und Energieanlagen durchgeführt. OBJECTIVES: Power plants based on the integrated combined cycle (IGCC) already in operation (Buggenum, 250 MW) or under construction (Puertollano, 300 MW) are generally characterized as demonstration facilities. The same applies to the development status of such plants in the US. The most attractive features of IGCC power plants are the extremely low environmental pollution and their capability to utilize various fuels such as coal, oil refinery residues, biomass, waste, etc., if the gasifiers are adequately adapted. Moreover, it is to be expected that such plants will attain higher efficiencies than conventional coal-fired power plants, thereby also reducing CO2 emissions effectively. Despite these advantages, further efforts are still necessary to achieve competitiveness with respect to the conventional steam power plant. There are three factors determining electricity generating costs, which can be influenced by design, process engineering and manufacture, namely the investment, fuel consumption and availability. Even if first-of-its-kind costs are neglected, it is to be expected that the specific investment of IGCC power plants based on the present design still turns out to be slightly above those of the conventional ones. As both the conventional steam power plant employing supercritical live steam and the IGCC of current design (Puertollano type) attain net efficiencies of 45 Prozent, an IGCC successor plant must show better performance to be competitive. As a consequence, investigations aiming at design improvements have to be carried out in order to accelerate market penetration and to benefit in this way from the environmental advantages of an IGCC in the near future. For this reason this Joule project 'Advanced Cycle Technologies' was set up by five partners from several countries of the European Union with the objective to study measures of cost reduction and efficiency enhancement and to jointly provide a basis for an advanced design. The studies also include co-gasification of coal and biomass in an entrained-flow gasifier suitable for IGCCs. The investigations comprise experiments on laboratory scale as well as computations, theoretical elaborations and design studies. Since two of the project partners are manufacturer and supplier companies of main components of the European IGCC demonstration power plants, the design studies also include the assessment of potential improvements with respect to feasibility and availability. The project work is subdivided into four task areas. Since most of the measures for efficiency enhancement influence costs and availability, the task areas are strongly interrelated. As any change in design and performance parameters influences the performance of other subsystems, repeated thermodynamic and economy analyses are performed. Therefore, close cooperation of the project partners is imperative.
