Objective THE PROJECT WILL CONTAIN THE FOLLOWING PHASES : - THEORITICAL WORK WITH LITERATURE STUDY AND BUILDING UP OF COMPUTER MODELS; - EXPERIMENTAL WORK WITH A EXISTING COLD RIG AND A PILOT PLANT. THIS WILL BE FOLLOWED, OUTSIDE THE SCOPE OF THIS PROJECT, BY THE CONSTRUCTION OF A PRESSURIZED COMBUSTION RIG. The basic design principles for a combined cycle power plant based on a multicirculating pressurised fluidised bed boiler have been studied. Software for evaluating the total thermal design, including steady state and dynamic response analysis, was developed. An empirical model for predicting emission levels, based on tests conducted with a 2 MW multicirculating fluid bed boiler, was developed. Different gas particulate separation systems were analysed and an inertial separator consisting of a preseparator and 2 stages of cyclones was chosen.In addition to establishing the general design and construction principles for an advanced fluidised bed based on a patented multicirculating boiler design, the study concentrated on acquiring the knowledge necessary to build a plant with a low environmental impact. An empirically based model was developed for calculating oxygen ion and nitrous oxide ion emissions from tests on a 2 MW circulating fluidised bed test plant. The project included an in depth theoretical study of a number of plant configurations using different types of turbomachinery. Software was developed for plant analysis during both stationary and dynamic conditions, including start up, control and shut down. Theoretical studies and tests were carried out to identify the best cleaning method and the technique chosen was based on a preseparator and 2 subsequent cyclone stages.THE OBJECT OF THE PROJECT IS TO FORM THE BASIS FOR AN ADVANCED FLUIDIZED BED CONCEPT,PRIMARILY FOR COMBUSTION AND GASIFICATION OF FOSSIL FUELS (COAL AND BIOFUELS),CONSISTING OF A MODERATELY PRESSURIZED (0-4 BAR) CIRCULATING FLUIDIZED BED WITH THE POSSIBILITY OF SELECTED PROCESS OPTIMIZATION. IT IS INTENDED TO FINALLY DEVELOP A FLUIDBED CONCEPT IN THE SIZE 30-100 MWT,WHICH IS OPTIMUM AS REGARDS : INVESTMENT,INDUSTRIAL ECONOMY,FUEL FLEXIBILITY,AND ENVIRONMENTAL IMPACT.
