Description: Das Projekt "6 MWTH koenig ludwig atmospheric fluidized bed combustion plant" wird vom Umweltbundesamt gefördert und von Ruhrkohle AG durchgeführt. Objective: To refine and improve atmospheric fluidized bed combustion technology such that: 1. coal fines, coal/water slurry, and fuels from conditioned domestic refuse can be used; 2. noxious emissions (especially SO 2, NO X, HF, HCP, and heavy metals) are reduced; and 3. ashes are disposed off without using special waste tips and in an environmentally acceptable manner. Energy substitution equal to 1500 TOE is projected. General Information: The project was conducted at the existing 6-Mwth AFBC pilot plant Koenig Ludwig in Recklinghausen. This plant, operating since 1980, serves as a steam generator for the industrial sector and provides decentralized heat for the public sector. AFBC technology has operated satisfactorily to date however, numerous technical improvements will be tested in 9 phases: Phase I - Additional equipment to facilitate testing and measuring during the project, the following were installed: storage facilities, handling equipment and feed systems; improvements to the steam generators including absorbent feed systems and secondary air injection system; and additional sampling points. Phase II - Minimization of SO2 HF, and HCL emissions feed devices, which uniformally distribute ultrafine lime powder above the nozzle plate, will be developed. It is expected that minimal additions of limestone will reduce noxious emissions and that ash as well as CaO content in the ash will also be reduced. Phase III - Combustion of washed coal fines prior to the project, the plant could handle only lump-size fuels up to 30mm. A simple and reliable fuel handling and feed system will be developed to handle coal fines. Phase IV - Combustion of coal/water slurry the suitability of coal/water slurry as an AFBC fuel will be tested with regard to mixture stability in transportation and storage, combustion, fuel efficiency and noxious emissions. Phase V - Combustion of eco-briq briquettes plus bituminous coal combustion of conditioned domestic refuse combined with bituminous coal will be tested with an emphasis on reducing emissions of inorganic chlorine compounds. Phase VI - SECONDARY AIR INJECTION The plant was equipped with secondary air injectors and the radiation chamber (freeboard) enlarged by using a suitable refractory lining. It was expected that this would improve the burn-up rate and reduce NO X and CO emissions. PHASE VII/VIII - ASH UTILIZATION AND DISPOSAL The solubility of trace element compounds in AFBC ashes were analysed. A lysimeter, consisting of a 10 m3 open tank exposed to the weather, will be used. Its rain and snow-water contents will be examined for trace element compounds. Potential applications for using AFBC ash was to be developed. PHASE IX - EVALUATION/REPORT Combustion of highly sulphur loaded GCA combined with bituminous coal to be tested with emphasis on reducing SO2-emission. Achievements: PHASE I: Systems and components for storing, feeding and distributing of granulated and pulverized limestone above
