Description: Das Projekt "6-MWth-Verbrennungsanlage 'Koenig Ludwig' mit atmosphaerischer Wirbelschicht" wird vom Umweltbundesamt gefördert und von Ruhrkohle AG durchgeführt. Objective: The objective of this Atmospheric Fluidized Bed Combustor (AFBC) project is fivefold: 1. To further develop and refine the AFBC technology for heat generation and system components 2. Expand the range of possible fuels used in AFBC to include residues from the 200 T/d coal liquefaction plant Bothrop and waste from refineries, petrochemical plants, tar and pitch processing and liquefaction plants. 3. Eliminate existing technical problems which diminish AFBC marketability. 4. Demonstrate the overall technical feasibility of AFBC's especially with regards to fuel flexibility (coke, low volatile, and raw coal). 5. Demonstrate the economic advantages of AFBC for heat generation. Assuming the demonstration plant replaces an oil fired heating scheme, it is estimated that energy savings will be 1,550 TOE/y. General Information: The Koenig Ludwig AFBC demonstration plant is a natural-circulation steam boiler with integrated fluidized bed combustion. The thermal capacity is 6 MW saturated steam at 17 Bar and 8. 85 T/h is generated to heat the recirculated district-heating water in a heat exchanger plant. Two completely separate conveyor systems are installed to charge fuel and limestone. One mechanical system feeds the fuel via screw conveyors from below into the fluidized bed; the other is a pneumatic system which charges the test fuels hard pitch and liquefaction residue, due to their low softening points, from above into the bed. Boiler ancillaries consist of a feed water treatment plant, flue gas cleanup plant (bag filters), and ash removal and disposal facilities. The demonstration was in four phases. The first two carried out under this contract being: Phase 1: Combustion tests were performed on various coal grades; primarily moisture-free middlings with volatile contents either in excess of 20 per cent roles than 10 per cent. A total of 103 single measurement series were done to examine coal grades with respect to burn-up rate, emissions, retention of noxious substances and the effect of fuel feed points. Phase 2: Combustion tests were performed on coke, hard pitch, and coal liquefaction residue to evaluate suitability for fluidized bed combustion and if emissions of hydrogen halides, sulphur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons, and trace elements were controllable. The project will cost an estimated DM 5,951 million. Achievements: Phase 1: Hard Coal Grades - Combustion efficiency was not significantly affected by coal grade at feed point location. In all cases, the carbon burn-up rate averaged 84-89 per cent, with peaks of + 93 per cent. - Optimum SO2 emission was obtained with nr 2 middlings, with a desulphurization level of + 95 per cent (CA/S = 4. 7 - 7. 9) at + 810 degree of Celsius. At an average NOx emission of + 600 mg/m3 in the main generating range, there are no significant differences between fuels. - Low volatile fuels were not found to be superior with respect to carbon monoxide emissions...
