This project aims at developing a predictor for ash behavior for biomass combustion in fluidised bed combustion conditions.The predictor would estimate the chemical composition, thermal properties, fouling tendency and sintering tendency of the ash.The ultimate goal is to be able to predict potential problems due to flue gas heat exchanger fouling and bed agglomeration in fluidised bed boilers, using advanced fuel analysis and a few boiler operating parameters as input data.
