Fluidized bed combustion facility improvements as a step forward in developing energy efficient and environmentally sound waste combustion technology in fluidized bed combustors

The project addresses improvement of thermal disintegration of various waste materials in the process of fluidized bed combustion (FBC) with utilization of generated energy, all in accordance with relevant environmental protection standards. Absence of appropriate waste treatment represents an important problem faced by industrial sectors in Serbia. The project aims to contribute to the solution of the problem specified, particularly in FBC facilities which represent the main focus of the research envisaged, where experimental trials indicate that the problem considered could be solved in energy efficient and environmentally sound manner. For the said purpose a reconstruction of an existent demonstration boiler used for FBC of heavy liquid waste is to be performed. The said shall enable industrial-scale FBC of various types of waste to be analyzed while performing continuous emission monitoring. In order to evaluate suitability of different waste materials for the FBC process all relevant regulations related to waste combustion shall be identified and listed. In addition, attention shall be paid to flue gas treatment system design as well as environmentally sound fly ash treatment. Numerical CFD simulation of FBC process shall also be addressed in order to investigate effects of fuel feeding rate and furnace parameters on combustion of different fuels. Computer software intended for normative calculation used in industrial boiler optimization shall be developed as well.
