DEVELOPMENT OF MULTI-SOLIDS FLUIDIZED BED COMBUSTION TECHNOLOGY FOR LOWER COST HIGH EFFICIENCY STEAM GENERATORS

Objective

THE PROJECT ENTAILS THE DESIGN, CONSTRUCTION AND TESTING OF AN 800 KW CIRCULATING FLUIDIZED BED COMBUSTION TEST RIG. THE ULTIMATE OBJECTIVE IS TO DEVELOP AN IMPROVED CIRCULATING FLUIDIZED BED DESIGN LEADING TO IMPROVED PERFORMANCE AND LOWER CAPITAL COST FOR COMMERCIAL PLANTS. A SUBSTANCIAL TEST RIG IS NECESSARY TO TEST THE NEW DESIGNS AND TO ENABLE A SERIES OF TRIALS TO BE CARRIED OUT FOR EVALUATION PURPOSES BEFORE FULL SCALE COMMERCIAL PLANTS ARE CONSTRUCTED.
Details of the design, construction, commissioning and operation of a multisolid fluidised bed (MSFB) test facility for research and development are presented. The technology was developed to reduce the capital cost of MSFB boilers with outputs below 40000 kg/hour of steam. The novel features included are described along with the results obtained under a range of test conditions. The performance of the process during various trials is described including details of the problems encountered and measures taken to resolve them. Based on the work completed and the results obtained recommendations for further research and development are also provided.
IT MAY BE ANTICIPATED THAT THE PROJECT WILL RESULT IN DESIGN IMPROVEMENTS WHICH WILL PROVIDE IMPROVED OUTPUT FROM SMALLER, MORE EFFICIENT, LOWER COST UNITS. WE EXPECT TO ESTABLISH OPTIMUM DESIGN/PERFORMANCE DATA WITHIN THE MAIN COMBUSTOR UNIT AND ALSO IN THE ESSENTIAL ANCILLARY EQUIPMENT. A COMPREHENSIVE SERIES OF TRIALS WILL BE CARRIED OUT ON THE TEST RIG FOR DATA COLLECTION PURPOSES. A 20% REDUCTION IN CAPITAL COST MAY BE ACHIEVED THROUGH DESIGN CHANGES LEADING TO PLANT SIZE REDUCTION, IMPROVED PERFORMANCE IN HEAT TRANSFER AND COMBUSTION EFFICIENCY. THE PLANT WILL BE CAPABLE OF BURNING A VARIETY OF FUELS AND COMPLY WITH EMISSION CONTROL STANDARDS. OTHER DEVELOPMENT WORK WILL LEAD TO REDUCTIONS IN MATERIALS FAILURE, MINIMIZE EROSION AND IMPROVE PLANT RELIABILITY.
