Abstract: Biomass-fired fluidised bed combustors are becoming popular in the agricultural countries like India. In this paper, a comprehensive thermo-economic analysis of a 7.5 MW biomass-fired bubbling fluidised bed thermal power plant has been presented. The energy and the exergy-based models have been formulated for the power plant. It has been found that for evaluating the performance of the biomass-fired power plant, compared to the energy model, the exergy model gives more reliable and accurate results. The boiler is found to be the source of the maximum exergy destruction and its design needs a revision. A break-even economic analysis of the power plant also has been conducted and various means of enhancing the profit have been suggested.
